Scope

1.1 This test method covers the measurement of the torque developed when Type IA child-resistant closures are rotated in the counter-clockwise direction. Type IA closures are reclosable continuous threaded closures that use a random push down while turning; no orientation of the push down force is necessary.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Significance and Use

These torque measurements are of value because the reverse-ratchet torque is a torque applied to the closure in the removal direction of the closure. For Type IA closures, it is essential that this torque be significantly lower than some defined level at which the closure might unscrew.

This test may be used to establish performance specification for this attribute.
