3 Terms and definitions
For the purposes of this International Standard, the following terms and definitions apply.
3.1 manufacturing batch quantity of control wire rope assemblies making up the same manufacturing series and of the same composition:
一with wire ropes from the same spool (identical material and diameter);
一with the same definitions for the extremities
3.2 test piece control wire rope assembly taken at random from a given batch
4 Requirements
4.1 General
The requirements specified by this International Standard are given in Table 1 and, apart from where otherwise specified, they also apply to control wire rope assemblies ready for use. The test temperature shall be, apart from where otherwise specified, ambient temperature. These requirements are to be taken into account along with the conditions which figure in all the other standards or specifications cited in the product or the definition documents for control wire rope assemblies.
5 Quality assurance
5.1 General
5.1.1 Approval of the manufacturer
rrhe manufacturer shall satisfy the quality assurance and approval procedures as defined by ISO 9001, ISO 9002 or Iso 9003. The aim of these procedures is to ensure that the manufacturer has a quality system and 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 rope 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 control wire rope assemblies shall be granted by the certification authorities in the buyer’s 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 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 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 9759 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 on six control wire rope assemblies (two in each of the above combinations).
The test specimen shall consist of
— a 500 mm length wire 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 from the batch. These swagings shall be carried out during the manufacture of the batch in question and tinder the same execution conditions as this batch.
If a control wire rope assembly is made tip of two end fittings and an intermediary fitting (ISO 9747), each sample shall made up of two specimens 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 manufacturer’s own marking, each control wire rope assembly shall be marked using the identity block specified in ISO 9762.
It shall be:
— either stamped onto a tab which is slipped onto the wire rope before swaging the last end fitting; or
— engraved on a sleeve fixed to the swaged part of the end fitting; or
— printed indelibly (ink, chemical engraving or other means) on one of the two end fittings without this
affecting the performance or reducing the service life of the control wire rope assembly. The inspection stamp shall also figure along with the marking.
7 Packing
Control wire rope assemblies shall be packed individually in paper packaging free from grease and carefully closed:
— in a rectilinear position; or
— rolled so that the diameter is at least 150 times the diameter of the wire rope.
The manner in which the assemblies are packed depends on whether the objects can be folded or not, but shall be such that there is no deterioration during transportation.
rIhe following indications shall figure on each package at least:
name and address of the producer;
— number of the deal or order;
— cluantity;
— identity block defined by the product standard or the definition document; packing date.
Special packing may be stipulated in which case it shall be specified in the order.
8 Certificate of conformity
All control wire rope assemblies supplied in conformity with this International Standard shall be accompanied by a conformity certificate supplied by the manufacturer.BS W 14 pdf free download.Aircraft control wire rope assemb lies
