Standard Test Method for Manual Shelling Two-Piece Child-Resistant Closures That Are Activated by Two Simultaneous Dissimilar Motions (Withdrawn 2018)

SIGNIFICANCE AND USE
This test method of applying force may be used as a standard test to compare the characteristics of a given design of container/child-resistant closure system with a standard or to compare the characteristics of container/child-resistant closure systems differing in construction.
It may be used to simulate certain manipulations that may be expected to occur in protocol testing (such as, prying with the teeth or objects in the room, biting, and pulling with the teeth).
This test method may be used to establish performance specifications.
SCOPE
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.
WITHDRAWN RATIONALE
This test method covered 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.
Formerly under the jurisdiction of Committee F02 on Primary Barrier Packaging, this test method was withdrawn in May 2018. This standard is being withdrawn without replacement due to its limited use by industry.
