The work of preparing International Standards i
15、s normally carried out through ISO technical committees. 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 par
16、t in the work. ISO collaborates closely with the International 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 p
17、repare International Standards. Draft International Standards 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 tha

The force is increased until failure occurs. 5 Apparatus and materials 5.1 Tensile testing machine, with: a) a jaw separation rate of (100
28、 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.

29、mens 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 in the open position with the locking device locked into the chain abo
30、ut 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 stop (see Figure 2). 7.2 Ensure that the locking mechanism remains in p
31、lace 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. 7.3 Record the type of failure as: slipping of locking mechanism; fai
32、lure 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 the corresponding values of F, recorded in 7.3, as the slider locking
