7.1.7. Non-Destructive Release and Re-Apply Mode
Combines two other options, the “Non-Destructive Release” and the “Multiple Applied” torque modes into one
option to save time, and prevent operator fatigue and injury. The test procedure is the same as the Non-Destructive
Release Mode with the addition of the Multiple Applied Torque Mode. This automatic reapplied cycle insures the
released closure’s pre-set target value of the applied torque.
7.1.8. Repetitive Applied then Release (Fatigue) Mode
This mode applies closure accurately and consistently to a sample container, then performs a release test,
automatically repeating the procedure as many times as your test criterion requires. Providing a true fatigue
test criterion of any quantity selected. Some uses are: seal integrity detection, leak testing, premature thread
ware, liner durability and child resistant mechanical failure determination.
7.1.9. Multiple Peak Mode
This option will measure the very first immediate release torque, then open the chuck, rewind, close and
then begin again testing for the next peak. Best suited for tamper evident closures requiring the continued
application of torque to break each of the tibs on the band.
7.1.10. Reverse Ratchet Mode
This option is based on the “D3472-97(2002) Standard Test Method for Reverse-Ratchet Torque of Type
IA Child-Resistant” ASTM specification.
7.1.11. Shelling Fixture Mode
This option is suited to comply with the ASTM recommendation: D3481-97(2002) Standard Test Method
for Shelling Two-Piece Child-Resistant Closures That Are Activated by Two Simultaneous Dissimilar Motions.
7.1.12. Strip Test
The strip test mode measures the peak torque value, where threads break/deform in an on-torque/application
cycle. This way you are able to measure the maximal amount of torque can be applied on a closure/container, without
permanent damage of the closure/container threads. It is an important information for the Production people, so they
can make sure that their cappers will never apply this amount of torque on the closures.
7.1.13. Various Dispenser Pump Head Tests
With different optional hardware modules, we can run dispenser pump tests, too. The following special
measurement methods are available:
Periodic topload application and spring load sensing/fatigue testing of dispenser pump heads.
Pump closure release torque measurement
Pump head release torque measurement.
7.1.14. Sealed closure torque testing methods
After analyzing your closure we can write the best torque testing algorithm for you to test special sealed closures.
7.1.15. Precision Applied and Release tests
Special tests have been developed by Sure Torque to test or precisely apply torque on syringes, vials and these
tests may be used in other low torque range applications, as well. The precision release test may be also used on CR
caps, too. In the optional special release torque mode – it mainly used to test the initial opening torque on special CR
closures, upon reaching the first drop in the release torque, the tester will continue the rotation and look for a next drop
in the torque to validate the previously measured release torque as the real initial release torque. If there is another
drop in the release torque, the previous drop was generated by the engagement of the CR cap’s outer and inner caps,
and determined to be a false readout. When there is no other drop throughout the release cycle, the first drop is
