3.3.3.5. Applied then Release Mode
This method may be used for fatigue testing. After applying the torque, the unit will automatically measure the
release torque value. This method may be particularly useful when someone runs studies on how does a
thread/material wears out in the function time/cycles. The applied then release mode runs as many times as it is
configured in the cycle number variable.
3.3.3.6. Multiple Release Mode
After measuring the immediate release torque the unit will try to measure a second peak torque value. The
release fallback for the second peak torque may be different than the first fallback. At the end of the test cycle the
display will hold the first and the second peak torque until you press “ESC”, which takes you back to the mode screen,
where the test was started. This mode may be useful to test the initial release torque of closure with a tamper evident
band. The first release fallback variable may be set to a low amount of torque to keep the sensitivity of the initial
torque test, and then the second fallback value may be set to a higher number to monitor the highest torque value
breaking the tamper evident band.
3.3.3.7. Release and Applied Mode
This is a cyclic mode again; the same as “Applied to Release” but this mode starts with releasing and finishes
with applying the cap. Mostly used on production lines for fast and accurate automated removal torque testing. The
containers are manually sampled regarding to quality assurance protocols, (based on rules like sampling every n-th
container, or sampling in every 10 minutes, etc) then the initial release torque is measured followed by torque re-
application. This way there is no product loss related to quality assurance processes.
3.3.3.8. Reverse Ratchet Mode
This is a special mode for testing child resistant caps in compliance to the ASTM recommendation D3472-
97(2002) Standard Test Method for Reverse-Ratchet Torque of Type IA Child-Resistant Closures.
3.3.3.9. Shelling Mode
This mode is for special cap testing and allows for shelling test up to 30 degrees. Ref: D3481-97(2002) Standard
Test Method for Shelling Two-Piece Child-Resistant Closures That Are Activated by Two Simultaneous Dissimilar
Motions.
3.3.3.10. 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.
3.3.3.11. Nondestructive Release Mode
Standard quality test. The tester will apply a certain amount of torque in off-torque direction to open the closure. If
it can open the closure, your container failed the test, and when the container remains close, the closure passed the
test. This way you may adjust your cappers until the tightened closure torque satisfies your low torque expectations.
This test may be used for quality assurance, and it also makes an acceptable/not-acceptable rule based quality
assurance process faster, because it is looking for the release fallback value only up to your acceptable lowest torque
value.
3.3.3.12. 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.
