1.1 This test method covers the measurement of the force required to separate (or "shell") the snap-fitted outer cap from the inner cap of Type IA, IB, or IC child-resistant closures.
1.2 This test method does not measure the force required to separate parts of a child-resistant closure system that were originally" screwed-on" instead of "snapped-on" (for example, pull a cap over or through continuous or multi-start threads when the cap was originally screwed on).
1.3 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only.
1.4 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.
