ASTM D3968-97(2007)

1.1 This test method covers the measurement of rotational torques of Type IIIA child-resistant closures as a means of monitoring normal functioning of the child-resistant package.

1.2 This test method is not intended to supplant preexisting closure or package specifications or preexisting incoming material test procedures.

This standard does not purport to address 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.

The application of this test method provides a means for evaluating one of the variables affecting the ability of the closure-container system to function as specified.

Variability in rotational torque measurements is probably due to the use of the torque meter to measure relatively small torque values, differences in critical package dimensions, and the aging of components.
