32、shall not slip in the end fitting and no wire shall be found to be broken upon visual or tactile inspection. The test shall be carried out with the wire rope in a straight line. Apply the load continuously and progressively (within a minimum of 3 s). Maintain it for 5 s. Then bring it gradually back

33、 to zero. Any sudden variation in the load recorded during the test shall be considered the sign of possible slippage of the wire rope in the end fittings and shall call for a very thorough inspection of the wire rope assembly and of its length. After this test, the control wire rope assembly shall

34、be carefully examined. 4.9 Performance under the minimum breaking load of the wire rope No slippage of the wire rope in the end fittings shall be allowed under the minimum breaking load of the wire rope concerned given in ISO 2020-1. Any eventual fracture shall only occur under a load equal or super

35、ior to the minimum breaking load and then never in or at the limit of the end fitting. The load shall be applied continuously and progressively until a load equal to 80% of the minimum breaking load is obtained. The remaining load shall be applied at a rate of about 10 N/s.

The aim of these procedures is to ensure that the manufacturer has a quality system an

40、d is capable of manufacturing, on a regular basis, control wire rope assemblies which fulfil the specified quality conditions. The manufacturer shall be approved by the certification authorities or their delegated representative, who may be the first supervisor. 5.1.2 Qualification of control wire r

41、ope assemblies The purpose of qualification inspections and tests of control wire rope assemblies is to verify that the conception and the manufacturing conditions of a control wire rope assembly and shall be such that the conditions of this International Standard are satisfied. The qualification of

42、 control wire rope assemblies shall be granted by the certification authorities in the buyers country, or their delegated representative, who may be the first supervisor. 5.1.3 Acceptance of control wire rope assemblies The purpose of acceptance inspections and tests for control wire rope assemblies

43、 is to verify as simply and cheaply as possible and with the inherent uncertainty of a statistical test, that the conditions of this International Standard can be satisfied. Acceptance tests shall be carried out by the manufacturer, or under his responsibility. The manufacturer shall be responsible

44、for the quality of the manufactured products. 5.2 Conditions for the execution of qualification tests The qualification tests are given in Table 1. They shall be carried out for each nominal diameter of the control wire rope assembly to the following combinations: a) an ISO 9737 or ISO 9749 or ISO 9

45、759 or ISO 9760 end fitting at the two extremities, b) an ISO 9737 or ISO 9749 or ISO 9759 or ISO 9760 end fitting at one extremity and an ISO 9747 or ISO 9748 end fitting at the other. For a control wire rope assembly, of a given nominal diameter, perform the checks and inspections given in Table 3

46、 on six control wire rope assemblies (two in each of the above combinations). Figure 4 Cross-section of the swaged part of the end fittingBSW14:1999 6 BSI 04-2000 Table 3 Inspections and tests for the qualification of control wire rope assemblies The test specimen shall consist of a 500 mm length wi

47、re rope, with the same characteristics as the naked wire rope used on the control wire rope assembly and from the same spool; end fittings identical to those used on the control cable assembly, swaged on the wire rope sample under the same swaging conditions as for the control wire rope assemblies f

48、rom the batch. These swagings shall be carried out during the manufacture of the batch in question and under the same execution conditions as this batch. If a control wire rope assembly is made up of two end fittings and an intermediary fitting (ISO 9747), each sample shall made up of two specimens

49、on which the following are swaged at the ends: one of the end fittings; an intermediary fitting (ISO 9747). 5.3 Conditions for the execution of acceptance inspections and tests The acceptance inspections and tests are given in Table 1. They shall be carried out on each identity batch in accordance with Table 4. 6 Marking In addition to the manufacturers own marking, each control wire rope assembly shall be marked using th
