ASTM D7257-06
Historical Standard: ASTM D7257-06 Standard Test Method for Automated Shelling Two-Piece Child-Resistant Closures That Are Activated by Two Simultaneous Dissimilar Motions
SUPERSEDED (see Active link, below)
ASTM D7257
1. 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. See Practice D 3475.
1.2 This test method is an alternative to Test Method D 3481, 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 (lbf) units are to be regarded as standard.
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.
