DIN EN ISO 10748:2011-06 EN ISO 10748:2011 (E) 3 1 Scope This International Standard specifies a test method to determine the locking strength of a slide fastener slider for footwear. The method is applicable to
18、all types of slide fastener that have a slider locking device. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document

20、s 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 elements, each attached to one of the opposing edges of two tapes, and movable slider that spans the interlocking elements, which,
21、 when moved in one direction, causes the elements of one tape to interlock with the elements of the other tape and, when moved in the opposite direction, causes the elements to disengage See Figure 1. 3.2 tape fabric panel to support the other elements of the slide fastener 3.3 slider means of drawi

24、that prevent unintended movement of the slider during use or wear 4 Principle The slider is locked on to the chain of the slide fastener and the locking device subjected to a tensile force applied at 180 to the locking device via the chain stringers. The force is increased until failure occurs. 5 Ap
25、paratus and materials 5.1 Tensile testing machine, with: a) a jaw separation rate of (100 10) mm/min; b) the capability of measuring forces up to 2 kN to an accuracy of better than 2 %, as specified by class 2 in ISO 7500-1; c) the facility to record the maximum force applied during the test.

26、 ISO 10748:2011-06 EN ISO 10748:2011 (E) 5 6 Preparation of test specimens 6.1 A minimum of three slide fasteners shall be tested. 6.2 Condition the test specimens at 23 C and 50 % relative humidity (RH) for 24 h before testing, and carry out the test in this environment. 6.3 Set each test specimen
27、in the open position with the locking device locked into the chain about 30 mm from the top stops. 7 Procedure 7.1 Set the jaws of the tensile testing machine (5.1) (50 5) mm apart and secure the test specimen centrally in the jaws, such that the top of each stringer is clamped adjacent to the top s
28、top (see Figure 2). 7.2 Ensure that the locking mechanism remains in place throughout the test, operate the tensile testing machine to increase the force on the test specimen until the locking mechanism slips or the test specimen fails. Record the force at failure, F, in newtons, to the nearest 1 N.
29、 7.3 Record the type of failure as: slipping of locking mechanism; failure of test specimen. 7.4 Repeat the procedure in 7.1 to 7.3 for the remaining test specimens. 7.5 For each type of failure, record the number of test specimens exhibiting that type of failure and calculate the arithmetic mean of
30、 the corresponding values of F, recorded in 7.3, as the slider locking strength.
