Significance and Use
This test method may be used as a standard test in the comparison of a given size and design lug-style child-resistant closure to manufacturer specifications, and in the comparison of similar closures of differing materials for determining strippage.
This test method may be used as a standard test to evaluate the continued effectiveness of the closure for child resistance and adult opening and reclosing throughout the expected use and shelf life of the package.
1.1 This test method covers the determination of the force required to cause a downward-force-while-turning lug-finish closure to be rotated across the container finish lugs (strippage) without downward force being applied to the closure (Type IIA closures).
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.
