4、IS0 member bodies). The work of developing International Standards is carried out through IS0 technical committees. Every member body interested in a subject for which a technical committee has been authorized has the right to be represented on that committee. International organizations, government
5、al and non-governmental, in liaison with ISO, also take part in the work. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the IS0 Council. International Standard IS0 4101 was deve
6、loped by Technical Committee ISO/TC 105, Steel wire ropes, and was circulated to the member bodies in October 1982. It has been approved by the member bodies of the following countries : Austria India Canada Israel China Italy Czechoslovakia Korea, Rep. of Egypt, Arab Rep. of Netherlands France Pola

9、eel wire for elevator ropes - Specifications 1 Scope This International Standard gives the specifications for steel wire to be used for elevator ropes only. It lays down : - the dimensional tolerances; - the mechanical characteristics. 2 Field of application This International Standard applies to ne
10、w steel wire of be- tween 0.25 and 1,8 mm diameter, used solely for manufacture of elevator ropes. It does not apply to steel wires taken from a rope. 3 References IS6 69, Steel - Tensile testing of wire. IS0 136, Steel - Simple torsion testing of wire. IS0 144, Steel - Reverse bend testing of wire.
11、 IS0 2701, Drawn wire for general purpose non-alloy steel wire ropes - Terms of acceptance. 4 Diameters and ovality 4.1 Nominal diameter of the wire, d The nominal diameter of the wire, d, is the diameter in milli- metres specified by the ropemaker on the order. It shall be the basis on which the va
12、lues of all characteristics are determined for acceptance of the wire. 4.2 Actual diameter of the wire The actual diameter of the wire shall be the diameter given by the arithmetic mean of two measurements, one being perpen- dicular to the other in the same plane. The arithmetic mean shall be within
13、 the tolerance limits specified in table 1, 4.3 Ovality of the wire The two measurements, taken as specified in 4.2, shall not dif- fer by more than half the total tolerance given in table 1.

18、a batch, the speed of application of the load may be higher than that indicated in IS0 89 but never at such a speed as to produce a 25 % elonga- tion between grips within 1 min.

The test relates only to wire with a diameter of 0.5 mm and over.21 The test shall be carried out in accordance with the procedure given in IS0 136. A test piece length of 100 d between grips is pr
20、eferable. When this length is impracticable, an alternative length shall be used at the discretion of the wire manufacturer. In this case, the minimum number of turns shall be proportional to the number specified in table 3, as the ratio of the alternative test length is to the standard test length
