BS EN ISO 10750:2018 pdf download – Footwear – Test method for slide fasteners – Attachment strength of end stops (ISO 10750:2015)
This International Standard describes a method intended to determine the attachment strength of the top and bottom stops of a slide fastener. The method is applicable to all types of slide fastener for footwear.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 19952 and the following apply.
3.1
slide fastener
means of securing two flexible materials consisting of interlockable teeth, each attached to one of theopposing edges of two tapes, and movable slider that spans the interlocking teeth which when movedin one direction causes the teeth of one tape to interlock with the teeth of the other tape and when theslider is moved in the opposite direction causes the teeth to disengage
Note 1 to entry: See Figure 1.
3.2
tape
fabric panels to support other teeth of the slide fastener
3.3
slider
means of drawing the two interlocking teeth together or apart as it traverses the length of the teeth
3.4
puller
piece of plastic or metal attached to the slider as a means of manual grip for the user to operate
3.5
teeth
individual component of the slide fastener or continuous plastic spiral which interlocks with an
opposing element
3.6
end stop/top stop
terminal components of the teeth to prevent the slider from disengaging from the teeth and tape
3.7
stringer
textile tape with an attached row of teeth designed to interact with a row attached to another tape
4 Principle
4.1 General
This International Standard describes the following methods.
4.2 Method 1 — Top stop attachment strength
The slider of a closed fastener is clamped in one jaw of a tensile testing machine and the bottom end of the fastener is clamped in the other jaw. The jaws are then moved apart and the force required to pull the top stops off the fastener is measured.
4.3 Method 2 — Bottom stop attachment strength (Slider-stringer method)
The slider of an open fastener is clamped in one jaw of a tensile testing machine and the two free stringer ends are clamped in the other jaw. The jaws are then moved apart and the force required to pull the bottom stops off the fastener is measured.
4.4 Method 3 — Bottom stop attachment strength (Stringer-stringer method)
The free stringer ends of an open fastener are fitted into the two jaws of a tensile testing machine. The jaws are then moved apart and the force required to pull the bottom stop off is measured.
5 Apparatus and materials
5.1 A tensile testing machine with the following.
5.1.1 A jaw separation rate of (100 ± 10) mm/min.
5.1.2 The capability of measuring forces up to 1 kN to an accuracy of 2 % as specified by Class 2 in ISO 7500-1.
5.1.3 The facility to record either the maximum force obtained during the test, or the force throughout the test.
5.2 For method 1 and method 2, a small hook attachment which will fit into the upper jaw of the tensile testing machine (5.1). The thickness of the hook should be small enough to fit through the hol in the puller of the test fasteners. A hook made from wire of diameter (1,6 ± 0,2) mm is suitable. The arrangements of these two tests are illustrated in Figure 2 and Figure 3.BS EN ISO 10750 pdf download.
