The work of preparing International Standards is normally carried out through ISO technical committees.

15、 Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the Interna

16、tional Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Stan

17、dards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subje

18、ct of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 10717 was prepared by Technical Committee CEN/TC 309, Footwear, of the European Committee for Standardization (CEN) in collaboration with ISO Technical Committee ISO/TC 216 Footwear, in accordan

19、ce with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

20、a test method intended to assess the burst strength of a closed slide fastener for footwear. The method is applicable to all types of slide fastener. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the editi

22、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 a movable slider that spans the interlocking elements which, when moved in one di

23、rection, 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 BS EN ISO 10717:2010ISO 10717:2010(E) 2 ISO 2010 All rights reservedSee Figure 1.

26、lide fastener is clamped, leaving an exposed circular area which is gradually stretched by forcing a small metal ball attached to a plunger through the centre. The force on the plunger at failure of the fastener is recorded. BS EN ISO 10717:2010ISO 10717:2010(E) ISO 2010 All rights reserved 35 Appar

27、atus and materials 5.1 A test machine with the following components. 5.1.1 A means of clamping the test fastener, leaving a central circular free area of diameter (25 1) mm. The design of the clamping system should ensure that the fastener does not slip during the test. An example of such a mechanis

28、m is illustrated in Figure 2. Figure 2 Example of a clamping device 5.1.2 A central plunger with a spherical ball of diameter (6,25 0,05) mm on the end and mounted in the centre of the circular free area of the camp (5.1.1). 5.1.3 A means of moving the plunger (5.1.2) relative to the clamp (5.1.1) a

29、t a speed of (0,20 0,05) mm/s. 5.1.4 A device for monitoring the force on the plunger within the range 0 to 800 N to an accuracy of 10 N. A suitable device is described in ISO 17693. See Figure 3.

30、r head Figure 3 Diagram of suitable apparatus 6 Test specimens 6.1 Three test positions are required. If three slide fasteners are available then each fastener should be tested at the centre of its length. If only one slide fastener is available then it should be tested at three points, one close to

31、 each end and one at the centre of its length. It is recommended, that where multiple tests are carried out on the same length, there should be a minimum of 15 cm between the testing points or a minimum length of 15 cm for single tests. 6.2 Condition the test specimens at 23 C and 50 % relative humi

32、dity for 24 h before testing and carry out the test in this environment. 7 Procedure 7.1 Close the test fasteners. 7.2 Ensure that the test machine is reset, with the central plunger (5.1.2) retracted to zero or minimum distension. If it has a maximum force indicator, turn it to zero. 7.3 Tightly cl

33、amp one of the test fasteners into the test machine (5.1) so that the centre of the chain is aligned with the centre of the ball (see 5.1.2). For heavy-duty slide fasteners, a very high clamping force will be necessary, whereas with light-duty fasteners, care is required to avoid excessively damagin

34、g the fastener. 7.4 Start the test by forcing the central plunger (5.1.2) into the test fastener at a rate of 0,2 mm/s. For the lastometer described in ISO 17693, this involves turning the handwheel clockwise at a steady rate of about one revolution per second. BS EN ISO 10717:2010ISO 10717:2010(E)

35、ISO 2010 All rights reserved 57.5 Continually observe the upper surface of the test fastener, at the centre where the maximum distortion is taking place. Record the force, in newtons, to the nearest 10 N, on the spherical ball when the fastener fails, this will usually be the maximum force recorded

36、during the test. 7.6 Examine the fastener and record the type of failure such as: chain or teeth separated, chain or teeth pulled off the stringer, chain or teeth broken. 7.7 Retract the plunger and remove the test specimen. 7.8 Repeat the procedure in 7.2 to 7.7 for the other two test positions. 7.

37、9 Calculate the arithmetic mean of the three maximum forces. 8 Test report The test report shall include at least the following information: a) a reference to this International Standard, i.e. ISO 10717:2010; b) a full description of the samples tested; c) the date of testing; d) the arithmetic mean

38、 of the maximum forces, as calculated in 7.9; e) the types of failure and the number of tests associated with each type; f) any deviations from this test method.
