ASTM D4760-91

Test Method for Proper Resecuring of Type 1 (Continuous Thread) Child-Resistant Closures (Withdrawn 1997)

SCOPE
1.1 This test method determines the proper resecuring of continuous thread child-resistant closures.
1.2 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety problems, 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.

Standard Test Method for
Proper Resecuring of Type I (Continuous Thread)
Child-Resistant Closures1
This standard is issued under the fixed designation D’4760; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, theyear of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
The integrity of child-resistant closures frequently is affected by the resecuring characteristics of
these closures by the consumer. Different closures may have different resecuring requirements. For
this reason this test method is limited to continuous thread chiid-resistant closures. The purpose of
this test method is to establish a framework for the definition and standards for “properly
resecured” continuous thread chiid-resistant closures.
