The tensile strength and yield point determination of wires and cables is determined by a straightforward tensile test. Rating a cable to its required load, without over-specification is important for keeping weight and material costs down. Whether a fine medical guidewire or a construction cable, testing to assure conformance to specification is essential. Mecmesin MultiTest tensile testers are available up to 50 kN, and fine wires can be measured on our low-end models below 500 N.

Adhesives, sealants and coatings require testing in a number of quite different ways, depending on their type, location and purpose. How do they perform in actual use? A butt-joint test can be used to pull apart equal bonded surfaces to test either the adhesive bond, or a coating.
For flat coated or painted surfaces, a test dolly may be bonded before being pulled off. This will test the integrity of the bond and the adjacent surfaces, including the performance of multi-layered coatings. Where bonded surfaces are subject to lateral forces, rather than being pulled apart, then a tensile or compressive lap shear test is appropriate. Flexible bonded surfaces are more amenable to peel testing, for example laminated belts. In all cases, Mecmesin has a suitable universal tester and fixtures.

Bearings and rollers are designed to rotate freely, so measuring their performance requires precision. Whether the bearing pivots, or rotates completely, the key points are the breakaway force and the torque required to turn. How do your bearings perform, given the small torque you are looking at?
Mecmesin precision torque testers can measure from a few mN.m up to 6 N.m, which means that a full and detailed signature can be acquired, to highlight wear or defects in manufacture. Mecmesin also designs and manufactures custom fixtures to grip bearings of any kind in correct alignment for precision testing.

Transit packaging, or shipping containers, of lightweight multi-wall construction are tested for integrity under crush forces, swung-pendulum puncture resistance, drop testing and environmental variance (typically wet testing). Do you have your own regular means of testing new designs and the quality of materials from new suppliers? Mecmesin universal testers are ideally suited to box crush, crease, fold and bend strength, puncture resistance under maintained force, and tear resistance. With suitable fixturing, the range of industry standard methods for testing fibreboard, including edge crush, ring crush, flat crush and stiffness can be performed with our MultiTest range of universal testers.

The quality of all brushes is in their ability to provide a lasting flexible contact with the intended surface. From a resilience point of view, tufts and bristles need to provide a consistent bending force, and remain separated and without fracturing or shedding of filaments. Handles and heads can be tested for bending strength, filaments can be flexed, and surface friction measured. How good are your brushes for their intended tasks?
Mecmesin testing machines can flexibly perform any of these tests, whether for the largest industrial machine brush heads, a paintbrush, toothbrush, or very small wire-wound surgical or cosmetics brush.

Do you have the means of testing your lifting straps and cargo tie-downs? Or tow ropes? Haulage companies can save time and money by regularly testing their own for safety compliance.
The haulage and heavy lifting industry use a wide variety of load restraints whose tensile strength must be assured for continued safe use. Clearly the tensile forces required are high, so Mecmesin twin-column MultiTest machines are a natural choice.
Grips suitable for different materials provide the means also for testing stitching, riveting and welds using the same machine.

Are your closures working for your customers? How likely are leaks or customer frustrations with difficulty in openability? Regular testing is affordable and protects brand integrity . Consumer packaging, especially in beverages, cosmetics and pharmaceuticals, employs a wide variety of closures, from flip-caps to wine corks. Many are fitted with tamper-evident, pilfer-proof or child-resistant features.
Testing for design, quality assurance, or for the closure process, require rapid turn-around with fixtures that may require an element of customisation for best fit. Mecmesin testers range from digital cap-testing instruments operated by hand, to semi-automated torque and force machines to remove cork stoppers. With Mecmesin’s Emperor™ control and data analysis software and a Vortex torque tester, slip torque, bridge torque, removal torque and reverse ratchet torque can all be measured, to understand the total performance of a screw-cap closure. Flip caps, push-fit closures and elastomeric vial closures can all be measured using Mecmesin MultiTest stands, for tensile measurement.

Are your building supplies up to scratch, guaranteed to perform as intended? Are you testing or trusting? New EU standards in construction materials may place new requirements on your business. Across the construction industry almost any kind of material and fabrication requires testing, from setting concrete, to blocks, beams, panels, tiles and membranes.
Mecmesin hand-held devices and sensors provide reliability and accuracy for in-situ testing, whilst our bench-top MultiTest universal testers offer everything you need for tensile and compression testing.

Are you paying for testing and certification, or confirming ratings of supplied lines? Perhaps you could save time and money by testing in-house.
Supplied frequently with strength rating, cord, rope and netting may also require repeat testing for safety assurance. Construction safety netting, for example, is required to be sampled periodically in order to be certified for use. Whilst there are companies that perform sample testing, this can result in equipment lying idle for an economic batch to accumulate. Mecmesin tensile testers can be used in-house, programmed for standard repeat testing, storing results and keeping expensive equipment in use.

If your cosmetics products are only subjectively tested by experts, you could benefit by capturing the experience and applying it as objective test data. In many respects, cosmetics are like food when it comes to testing. Texture, strength, resistance to penetration, spreadability, firmness etc. are all features requiring regular production-line testing. Preparations are formulated, and typically poured, formed and compressed for daily, repeated use. At the formulation stage, testing the texture of the product against objective data relating to customer expectation is vital for product consistency and improvement.
Mecmesin testers provide the ability to capture the objective data underlying user experience, and use this in preference to reliance on subjective testing. Mecmesin universal testers are also available with touch-screen operation, making them ideally suited to production environments.

What is the end-user experience of your cosmetics packaging towards end of use? Working well, or falling apart? Testing both helps your design and your quality assurance. Cosmetics packaging frequently features the means of application and dispensing, including propelling lipsticks, mascara brushes, pumps, sprays, and rollers. Many are designed for repeated use over considerable time. Mecmesin testers can meet the needs of the very light torque for a lipstick, through to the variety of tests required for assessing the integrity of more complex multi-part applicators.

Aperture closures, aside from their durability, must be safe, reliable and easy to use. In combination with locks, handles and catches, it is frequently the effort required in using them that needs to be assessed.
Mecmesin instruments are used to measure the closing forces and safety response in sliding mechanised doors, for example, or window winders, and emergency exits. This can be best measured in situ, whilst the physical strength, for example of security shutters, can best be measured as a bench test. Mecmesin provides both accurate digital instruments and computer-controlled bench-top testers for these kinds of fabrications.

When conveyors break down, production stops, resulting in lost time and money. Are you confident of your specifications and the durability of your products? Computerised testing helps strengthen your brand identity.
The components of drive belts and conveyors involve bearings, link elements, weld joins and belt membranes. These require rigorous testing in design and as assemblies, for which Mecmesin tensile testers are an ideal solution. Whether the tensile strength of a link, the adhesive strength of a weld, separation of layers or elongation at break, we can supply the appropriate and affordable tester and fixtures.

The design of your component was good, the materials well selected, but have you a means of testing the production line output for quality and compliance to specification? Are they strong enough? Tight enough? Moving as they should?
Testing the robustness and integrity of individual and assembled components can involve almost any kind of test. The important factors are deriving repeatable test programs where industry standards may not apply, and gripping the part correctly for consistent testing. Mecmesin’s Emperor™ software is fully programmable, with test programs retained in a library for instant recall. Emperor can be used to analyse the results, and give instant pass/fail indication. In a production environment our touch-screen controlled testers provide ease of use with minimal training.

Is your brand reliant on third party electronics, or do you need to know that your own components will withstand prolonged use? With your own tester, you can help protect your reputation for quality.
Electronics components and assemblies are found in the most demanding environments, and despite massive integration and sub-miniaturisation, require physical testing. This includes measuring the shear and pull removal forces from printed circuit boards, the flexural properties of the boards themselves, the peel resistance of conductive tracks, and the precise torque of the lightest rotary controls and presets. Mecmesin testers can be used to apply your own or industry standards, in an accurate and repeatable manner, either in design or post-production quality assurance.

A switch that fails to turn off can be more dangerous than one that fails to turn on. How do you test your switches for ease of use, reliability and quality of construction?
Mecmesin testers, driven by Emperor™ control software, can measure not only the force required to operate a switch, but profile the whole action for positive response, undue friction, or defects. Continuous cyclic tests for component wear can also be done, and, as in the case of push-to-break switches, the electrical connection itself can be used as an event in the test program. For simple rotary switches, manually-operated digital torque testers may be appropriate, whereas for compression tests of rocker switches or membrane switch buttons, a MultiTest is ideal.

Have you ever pulled a stud out of your jeans? Don’t let it be the story of your customer.
Fabrics fasteners such as poppers, clips, zips and buttons are designed to be pulled, but over the lifetime of a garment should not pull off. Similarly, trimmings and adornments should not detach if accidentally caught, or during washing. In the case of children’s garments, there may be a safety issue in the choking hazard of a detached item. For protective clothing, the consequences of holding failure as much as detachment, could be more serious. The only way to test the security and performance of riveted, clipped and stitched items is to have a reliable, accurate and repeatable pull measurement system. Mecmesin tensile testers are widely used for this kind of test, with a variety of grips and fixtures designed for the awkward handling of fabrics fasteners.

Yes, we have even tested hot air balloon fabric! But you can test your own regular fabrics and yarns in-house to industry standards. Tensile and compression tests are applied to fabrics of any kind, to test resilience in use. Some tests, such as the Mullen burst, require dedicated machines, but universal testers, like the versatile Mecmesin MultiTest range, can be used for testing the tensile strength of yarns, tear resistance of woven fabrics, elongation of geomembranes, or resistance to puncture of materials in protective apparel.
The same machines can be used for fasteners, trimmings, stitching and seams, or the adhesive strength of Velcro strips.

Are you auditing your torque fasteners? Pulling your fixings to destruction? Confident of every fastener? Regular computerised testing confirms the quality of supplies and of your constructions.
The integrity of assemblies and constructions almost invariably depends on the security of industrial fasteners and welds. The torque required to secure a threaded fastener, and to audit fastenings on completed assemblies, must be measured accurately and reliably. The tensile strength of the fastener itself has to be quality assured, and the force required to be held must be within adequate safety margins. These tests require instruments that can provide reliable and repeatable test routines and profile movement and breakdown in fastened joints. Mecmesin test systems for force and torque, driven by Emperor™ control software, can provide for your needs with affordable versatility.

Do your cartons look good on the supermarket shelf? Does anyone get frustrated because a container has collapsed in their bag, or won’t open easily at home? Test before it happens, and protect your brand. Food containers, packaging and trays provide mechanical protection for contents. The seal for modified atmosphere packaging (MAP), or for retorts and pouches of fluid contents, clearly must provide maximum seal but be readily opened by peel or tear. For stocking and stacking in-store, trays and cartons require crush resilience, whilst lids, closures and perforations must be user-friendly.
At the level of construction, the creasing force of carton packaging and unfolding force is important for the filling machines, since packs supplied flat must open without bending or tearing. A wide variety of materials are used, increasingly with an eye to minimising, or using recycled constituents, so testing in design as well as quality assurance for use, is essential. A Mecmesin universal test system provides an affordable and versatile solution for all these test requirements, from design to production-floor quality control.

Do your furnishings products bounce back as they should? Do you test your suppliers’ materials for consistency? Do you have a testing system so that you can test your products in-house and save money on expensive outsourcing? Among all the tests that furniture requires, some require testing for repeated use and performance. Components designed for bending or cushioning should return consistently and predictably to form. Furniture coverings and fastenings can be tested, as can adhesive bonds of joints. Struts, strapping and foams can be tested for flexure, for compression and recovery. Mecmesin MultiTest systems and fixtures are an affordable and versatile solution for these aspects of furniture and soft furnishings.

How tough is your toughened glass? How much force can your ceramic floor tiles take? Or how high do you stack your bottles? Is that new jar design as strong as the last? A computerised compression testing system will tell you, accurately, every time.
Though stronger than plastic containers, glass is also heavier, and the same requirement applies, to balance weight and strength whilst optimising material thickness. Whilst a PET bottle will ‘give’ under top-load, glass failure is catastrophic. Testers with higher crush capacity and safety enclosures are therefore required. Ceramic materials and glass panels are tested for their flexural strength and breaking point, using three-point bend fixtures. For all these applications, Mecmesin MultiTest universal testing machines provide an ideal solution.

Many industries manufacture and use grips, handles and winders, from the very small, for example, watches, to the large, such as door handles in constant daily use. The effort required to use winders, whether manual or motorised, is an important factor in design and in assessment of durability. The performance of handles may be linked to locking mechanisms and spring strength, or to fixings in the case of rigid handles.
The variety of force and torque tests required can all be performed using Mecmesin test equipment, from the precision torque Helixa to the heavy-duty twin-column MultiTest compression tester. Since handles and winders are usually ergonomically designed, gripping them in test equipment may require custom-engineered fixtures. Mecmesin engineers regularly design and manufacture to customer requirement.

It’s a tough world for those cards and tags. Have you found total confidence in reliable and repeatable testing of your security items? Have you considered a computer controlled universal tester? The two main factors in security tags and cards of all kinds, are durability and resistance to misuse. Regular testing ensures quality assurance, but a variety of tests are required. Identity cards must not peel, even if edges become damaged, and there must be no way of delaminating them in order to alter their details.
Chips in finance cards must not lift or become displaced by regular use in readers over their intended lifespan. Security tags in stores must be easily released from goods legitimately, but be strong enough not to be released my manual means. Animal identity tags in agriculture are also part of veterinary tracking, so strength alone (resistance in normal use) is not the only requirement. A tag must also become unusable once separated. For all these tests, Mecmesin MultiTest tensile testers provide the required versatility, including design by our engineers of custom fixtures if required.

Confident in every click? Whatever it is that clicks into place, you can measure precisely what it takes, and whether it’s the smooth, positive action you intend.
Locks, catches and clips are found everywhere, from ultra-high security, to everyday use, simply as exchangeable fastenings, and down to the lightest hold. In most cases they must operate within given tolerances to lock, unlock, simply hold, and provide correct resistance to opening. Cyclic testing for wear and tear may also be a requirement, and they may be combined with the operation of locks and handles. Release forces and closure effort are frequently very different, so for example measuring a high tensile strength but also a manually-applied locking movement can be quite different tests. Mecmesin MultiTest series universal force testers are ideal, with appropriate loadcells and fixtures for different applications.
Mecmesin Vortex torque testers provide all you need for rotary locks and clips. It can also be necessary to measure locks and catches in situ, requiring hand-held instruments. Mecmesin digital force gauges provide the accuracy and means of data capture for these applications.

Do you know what it takes to lift, pull or push goods or equipment in your workplace? Digital force gauges at the point of use can help you provide the right advice for health and safety. A central aspect of health and safety in manual handling involves assessment of the manual effort required to push, pull or turn heavy or bulky items.
If there are limits at which handling equipment is to be advised, then the actual forces required must be measured. Mecmesin provides a range of digital instruments and sensors that can be used in flexible combinations as required by actual working environments.

New high-strength magnets have taken over in the home, office and in clothing and jewellery, where adhesives or mechanical studs used to be. Unlike poppers and clips, they require no force to attach, but have you selected the right magnet? How do you test for this? Neodymium magnets are also widely used as fasteners for bags, jewellery and clothing, and here the pull strength must be strong enough for retention without damaging the items they secure when pulled apart.
Testing the design and suitability of electromagnets, relays and solenoids can also include the application of different electrical inputs, to determine performance through the complete travel of moving parts. This profile of magnetic devices is vitally important for accurate and predictable behaviour. A Mecmesin MultiTest tensile tester with Emperor™ control and analysis software will provide a complete picture of the forces over distance in magnetic and electromagnetic devices, as well as applying a wider range of tension or compression tests on the assemblies where they are in use.

Many of us know the frustration of a trigger spray or pump dispenser that simply does not work properly. Is your brand on that new, full container of a favourite product that’s going nowhere? Point of production testing ensures quality and protects customer confidence. Even a simple pump dispenser has around 10 components which may not be from a single source, and maybe you buy in your pump tops complete.
Quality assurance testing of pump and spray assemblies can show up potential problems, long before the production line has filled 10,000 faulty containers for despatch. Any drift away from specification in a batch can be detected for immediate investigation before faulty products are fitted. Mecmesin compression testers at the production line can be programmed for rapid sample throughput, applying instant-access programs run at the touch of a button.

Does it twist, slide or press as designed, and is this a subjective impression? Or have you tested your controls against objective criteria, using an accurate programmable test system for repeatable testing?
Manual controls, pedals and switches are designed for positive or smooth action and ease of use. Human forces or effort applied to foot- or hand-operated equipment in normal use are used to derive test programs based on an expected range of forces.
These objective measures can be used to ensure over-application of force does not break a control, or lead to malfunction. Mecmesin MultiTest force test systems with Emperor™ control software provide the required repeatability and accuracy for production line quality control as well as for design, to show not just operating force, but any lack of smoothness or overtravel, which may indicate manufacturing problems. Hand-held digital instruments from Mecmesin are also widely used to measure operation of controls in situ, rather than as a component bench test.

The recyclability of metals makes them suitable for many containers, where rigidity and heat sensitivity, or resilience to contents also matter. As with any packaging, minimising the amount of metal required is an important element. Knowing the safe stacking height is important for storage, as is knowing the resistance to lateral forces in use.
International standard methods for column crush are reliably applied using Mecmesin MultiTest universal testers, with all the versatility for performing related test requirements on closures and transit packaging.

If you manufacture or supply medical devices or aids, you need accurate and reliable computer-controlled testing systems. Few mass-produced disposable items require as high reliability as we expect from medical devices. A cannula, a Luer lock, a tube connector, dermal patch, bone screw or guide wire, are representative of very simple items with very high specification, to which international test standards are applied. Mecmesin universal testers and torque testers are used to apply these tests accurately and with complete repeatability.
They have the versatility to be programmed for the full range of test types required. Mecmesin test equipment is also used in medical research for the design of prosthetics and aids, to apply expected forces and measure the product response. Mecmesin universal MultiTest systems can be programmed with the required standards you need for rapid and reliable testing, including sample tracing for audit trail.

The virtue of paper is in being highly printable, with good tensile strength. Its tear properties make it suitable for intended easy opening, but can present difficulties in handling. Mechanised print and production moves paper at very high speeds, so understanding the tear resistance of each paper type and its friction properties is very important so that machinery can be properly adjusted. With so many paper types from different sources, and their varieties of coatings, a Mecmesin MultiTest universal tester, programmed for each type of test, is an invaluable cost and time saving investment.

If you manufacture or supply pharmaceutical and sterile packaging, you need accurate and reliable computer-controlled testing systems to apply industry standard test methods. The most stringent standards apply to pharmaceutical and sterile packaging. Designed for maximum seal but minimum peel, aseptic semi-rigid and flexible packaging must survive sterilization processes and retain total integrity to the point of use, and then be opened, often with surgical gloves, in a predictable and controlled way.
Equally, elastomeric vial closures and blister packs must perform reliably, as must any external packaging. Only accurate and repeatable testing to industry standard methods can ensure full compliance with quality standards. Mecmesin universal MultiTest systems can be programmed with the required standards for rapid and reliable testing, including sample tracing for audit trail. Pharmaceutical packaging also makes use of tamper-evident and child-proof closures (CRCs), for which a Mecmesin Vortex torque tester is ideal. Using the same software as for the MultiTest, its operation requires little additional training.

Do you have an accurate and ongoing picture of the performance of your foils or films? Whether as a manufacturer, supplier or user, regular test data and analysis are essential to keep things rolling smoothly.
Films and foils are widely used for labelling and for sealing. In production, inks and adhesives are applied, and they may be heat-sealed onto blister packs or retort containers. They may simply be used to wrap, or be used to create laminates. Friction properties are therefore an essential part of production flow, as are resistance to tearing, stretching and blocking.
Mecmesin MultiTest systems and fixtures provide all you need for any of the required performance tests for your foils and films, including peeling and bursting after application, for example in packaging.

The only way to test the resilience of many products is to subject them to forces beyond specification, as complete assemblies. It is one thing to test component parts, but how they interact in a complex assembly can be less predictable. It may be the integrity of the item that requires being pulled, pushed or twisted, or a moving part needing to be taken to extremes, but it is the working of the whole together that needs testing.
Does one part distort or break first, and what does this lead to as a consequence? Mecmesin MultiTest tension and compression testers can apply forces from less than 1 kN up to 50 kN. The Emperor™ control and analysis software provides fully-programmed repeatable testing, with complete detail in the response of the assembly to the applied forces. The same tester can be used in tension of compression to apply a variety of tests, with programs recalled at the touch of a button.

How are you top-load testing your bottles? Will those sachets burst if they are packed too tightly? What are your stacking limits based on? Plastic bottles and containers combine attractive design with precise engineering to ensure economy of materials with user-attractiveness, ease of use, packing density, and strength.
Wall thickness and profiling are carefully adjusted, but physical testing ensures best design and quality assurance in production. Mecmesin test systems are designed for ease of use on the production floor in quality control, where repeated and rapid testing is required.

Do your customers stick with you? Routine quality testing of your tapes and labels for peel, stretch and tear will help ensure they do.
Pressure sensitive adhesives may be required for a very strong fixing, or to be peeled for opening and resealing. Some may be used for security and must result in the destruction of a label, for example, if peeling is attempted. Standard methods set by PST, Afera and ASTM for PSA tapes and labels are commonly used.
These define the sample preparation and mounting method, the type of peel test applied, and require standard test equipment for maximum repeatability. Mecmesin MultiTest systems are an affordable and versatile solution to all your peel test requirements.

Probably all of us have felt frustration in opening a packet and having to resort to knife or scissors. Is your brand on that lid? In-house testing in the production line can ensure that it is not. Food pouches, popular for packing density and low-volume disposal, rely on welded seams, and have access point closures for peeling, piercing, tearing, and sometimes resealing. Retorts with peel-back lids should not tear or delaminate in the process.
All these tests, for opening, and for resilience in transit and perhaps refrigeration, can be performed with a Mecmesin MultiTest universal tester, fitted with the appropriate grips, fixtures and, if necessary, failure containment.

Don’t let your brand go down the tubes! Your customers can switch suppliers if your quality slips, but accurate, in-house, routine testing is affordable and practical. As gas or fluid conveyors, tubes may be installed and fixed, or mobile and flexible. All will be jointed and connected for purpose, and may be constricted if twisted or bent.
Knowing how far a bend can go, how strong a connection is, what force is required to pull a tube off or push it onto a connector, or to screw the parts together, is vital information, that can be acquired accurately with a tensile or compression tester. Mecmesin testers, for screw torque, flexure, tension and compression can meet all these needs, fully programmed for repeatable testing.

Seals and seams, whether elastic, adhesive or welded, are designed to hold under various forces that may drive or pull them apart. Failure may be due to internal pressure, peeling or tensile shear. Some seals are designed to fail at a given force, either for opening or to release pressure for safety. In all cases, the point of failure is important, and for all test types there is a suitable Mecmesin MultiTest, computer-controlled for repeatable testing at the touch of a button. Routine testing of seal strength is a vital part of quality assurance, and is best done at the point of production.

Sports brands are valuable; you want to be the preferred one, so performance and durability are key factors, assured only by constant and routine product testing.
A lot is expected of sports equipment, and much of it is taken to extremes of endurance. And yet we expect consistent high performance from brand new to repeated use. Quality determines the lifespan, and lifespan adds to brand preference. Mecmesin test systems are in use worldwide, measuring the flexure of surfboards, the bounce of tennis balls, the strength of fishing lines, compression and recovery of cricket balls, to secure attachment of sports shoe cleats and resilience of sport-specific clothing.

Carton in one hand, half a tear-off strip in the other? It’s all too familiar, but you don’t want it to be your brand. In-house testing of your tear openings is affordable and ensures consumer confidence. Cardboard and paper packaging, bag or paper rolls, regularly employ perforated tear strips for controlled opening and separation. To ensure the die-cutting process is working optimally, samples need to be tested. Specifications and methods will be particular to products, but repeatable testing to expected manual forces as in normal use, is essential.
The pattern of a controlled tear is also important, such that a strip, for example, tears fully end to end without breaking. An affordable Mecmesin tensile tester, with Emperor™ control and analysis software, can perform all your routine packaging tear tests.

Importers, manufacturers and retailers have a particular responsibility for children’s toys and games. Do you have the means to test your goods for compliance? Toy safety is strictly controlled to avoid the separation of parts that may present a choking hazard or cause an injury. In addition, toys will only be popular if they are durable and continue to perform after robust and sometimes unpredictable play.
Whether a feature is tested for detachment, a button is pressed to ensure its repeated function, or a part is flexed for strength, an ideal reliable and affordable solution for compression and tensile testing, is a Mecmesin MultiTest, with a range of suitable grips and fixtures.

The strength of any cable or wire rope is only as good as its attachments. Swages, eyes and shackles, terminals, clamps and ferrules on the cable, or eye-bolts that they attach to, can be the weakest point. These components can be bench-tested for correct fitting and tensile strength using Mecmesin MultiTest tensile testers. Where the application is, for example, on a vehicle or a building, hand-held digital instruments and sensors can be used.
