ZHTest Method: SATRA TM52
Strength of slide fastener pullers
March 2018
SCOPE
This test method is intended to determine the strength of a slide fastener puller and its attachment to the slider. The method is applicable to all types of slide fastener.
PRINCIPLE
The slider and puller of a test fastener are clamped so that the puller is perpendicular to the slider body.
Method 1: Tension – The force required to pull the puller from the slider in a direction parallel to the longitudinal centre line of the puller is measured.
Method 2: Torsion – The torque required to twist the puller from the slider about the longitudinal centre line of the puller is measured.
