Full Description

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. See Practice D3475.

1.2 This test method is an alternative to Test Method D3481, a manual test procedure.

1.3 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).

1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.5 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.
