13、YMMETRICAL PAIR/QUAD CABLES FOR DIGITAL COMMUNICATIONS Part 6-2: Symmetrical pair/quad cables with transmission characteristics up to 600 MHz Work area wiring Capability Approval Sectional specification FOREWORD 1) The IEC (International Electrotechnical Commission) is a worldwide organization for s
14、tandardization comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, the IEC p
15、ublishes International Standards. Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in
16、 this preparation. The IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an
17、international consensus of opinion on the relevant subjects since each technical committee has representation from all interested National Committees. 3) The documents produced have the form of recommendations for international use and are published in the form of standards, technical specifications
18、, technical reports or guides and they are accepted by the National Committees in that sense. 4) In order to promote international unification, IEC National Committees undertake to apply IEC International Standards transparently to the maximum extent possible in their national and regional standards
19、. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter. 5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with one of its
20、standards. 6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61156-6-2 has been prepared by subcommitte
21、e 46C: Wires and symmetric cables, of IEC technical committee 46: Cables, wires, waveguides, RF connectors and accessories for communication and signalling. The text of this standard is based on the following documents: FDIS Report on voting 46C/515/FDIS 46C/523/RVD Full information on the voting fo
22、r the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee has decided that the contents of this publication will remain unchanged until 2006. At this date, the
23、publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended.61156-6-2 IEC:2002(E) 3 MULTICORE AND SYMMETRICAL PAIR/QUAD CABLES FOR DIGITAL COMMUNICATIONS Part 6-2: Symmetrical pair/quad cables with transmission characteristics up to 600 MHz Work area wiring Capability Appro
24、val Sectional specification 1 General 1.1 Scope This part of IEC 61156 applies to Capability Approval requirements for cables intended to construct patch, equipment, and work area cords for digital communications in accordance with generic specification IEC 61156-1-1 and Clause 4 of the sectional sp
25、ecification IEC 61156-6. Clause 2 refers to the content of the Capability Manual. Clause 3 refers to the related quality layout. Clause 4 is related to the maintenance of the Capability Approval. NOTE Quality assessment belongs to the negotiation between customers and manufacturers. The following cl
26、auses are intended to be a guide when there is a request for a third-party Capability Approval. However, it may also be used as the basis for second-party or self-certification. 1.2 Normative references The following referenced documents are indispensable for the application of this document. For da
27、ted references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

29、pecification 2 Contents of the Capability Manual 2.1 Description of the cable families related to the capability domain This subclause of the Capability Manual describes the family/families of cables for which Capability Approval is required as follows. a) Reference to the applicable standards (e.g.
30、 sectional specification, detail specifications, etc.). b) Description of the cable constructional details, for example size of conductors, insulation material and insulation dimensions, type of cable element, i.e. pairs or quads, screening material and dimensions, screen construction, sheath materi
31、al and dimensions, outer diameter, maximum cable size and maximum cable length. c) Additional characteristics or requirements not covered by the applicable standard. 4 61156-6-2 IEC:2002(E) 2.2 Identification of the manufacturing process, equipment utilization and manufacturing instructions For each
32、 family of cables the manufacturing processes shall be identified; for instance, by means of a flow chart as given in Annex A. For each manufacturing phase it is required to specify: a) description of available machinery and corresponding working instructions; b) construction techniques; c) process
33、boundaries related to each phase of manufacturing; d) test and inspection points in the manufacturing process. An example of such manufacturing process step identification is given in Annex B. 2.3 Policy on rework and repair This subclause describes the permissible operations of rework and repair an
34、d their related operative instructions. 3 Quality Plan 3.1 General Reference is made to 2.2.4 of IEC 61156-1-1 with regard to process control. At a minimum the following items shall be identified and considered: a) identification of manufacturing stages; b) identification of those characteristics wh
35、ich depend upon process phases and related tests; c) identification of all testing procedures; d) acceptance limits and criteria for the process and manufacturing stages; e) sampling and sampling plan (type and frequency). An example of such a sampling plan is given in Annex C. 3.2 Selection of Capa
36、bility Qualifying Components (CQCs) It is necessary to point out that the manufacture of cables is composed many process phases that are continuous and not independent of each other. Hence, the products in each phase are not discrete production components. For this reason, the CQCs are presented by
37、representative samples taken from each phase or from the finished products. NOTE It is recommended that the trend of the results and/or statistical quality indices related to the tests carried out be examined. 3.3 Purchased raw materials The Quality Plan shall include a list of the raw materials use
38、d for the manufacture of a cable family, their corresponding purchasing specifications, and procedures for incoming inspections. 3.4 Design criteria (if applicable) The Quality Plan shall be include a list of the documentation concerning the design of the cable family either directly or by reference
39、 to the manufacturers internal instructional documents.61156-6-2 IEC:2002(E) 5 The main items are a) the design of each product family; b) the material selection criteria; c) rules for the dimensioning of the cable elements. 4 Maintenance of Capability Approval The maintenance of the Capability Appr
40、oval shall be based on the examination of a) the documentation related to the process control carried out during the period considered; b) the test results on the finished products; c) the review of the manufacturing lines in accordance with the Capability Manual. 6 61156-6-2 IEC:2002(E) Annex A (in
