ASTM D4846 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. ASTM D4846 requires attachment of snaps to specimens using specifications provided by the producers of the snaps. ASTM D4846 is used to establish correlation to wear conditions and for comparing different brands and types of snap fasteners.
ASTM D4846 requires a constant rate of extension (CRE) type testing machine conforming to Specification D 76 with a rate of traverse of 305 mm (12 in.)/min. The following universal test machines meet the requirement. By means of our testing expertise and modular product design, we will help find the solution that is right for you.
