Closure Torque Testers
The application torque of closures must be controlled in order for the closures to perform properly in the field. Closures must be applied tight enough to maintain a seal and to resist closure back off, but must not be applied so tightly that the end user cannot remove the closure.
Closure torque or cap torque testing involves a range of tests for events designed into screw caps and unthreaded stoppers. It can include a measure of the turning force required to overcome safety features (e.g. child-resistance closures (CRC) Types I and II), tamper resistance, and to open, or to secure a twist cap or lid.
Types of closure torque test
- bridge torque (torque to break the bridges of a tamper-evident band eg. on ROPP closure)
- incremental torque (torque measured in very small steps, usually when in contact with an internal seal)
- removal torque..... (torque to release the closure)
- reverse ratchet torque..... (torque applied without downward axial force on a CRC)
- strip torque ....... (torque to 'jump' or strip the thread)
