scope:

1.1 This test method covers the determination of the force required to disengage snap fasteners by a pull perpendicular to and parallel with the plane of the snap fastener.

1.2 This test method requires attachment of snaps to specimens using specifications provided by the producers of the snaps.

1.3 This test method is used to establish correlation to wear conditions and for comparing different brands and types of snap fasteners.

1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.

1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
