13、TRICAL PAIR/QUAD CABLES FOR DIGITAL COMMUNICATIONS Part 5-2: Symmetrical pair/quad cables with transmission characteristics up to 600 MHz Horizontal floor wiring Capability Approval Sectional specification FOREWORD 1) The IEC (International Electrotechnical Commission) is a worldwide organization fo
14、r standardization 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 IE
15、C publishes 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
16、 in 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,
17、an 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 specificati
18、ons, 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 standa
19、rds. 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 i
20、ts 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 61156-5-2 has been prepared by subcommi
21、ttee 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/506/FDIS 46C/521/RVD Full information on the voting
22、 for 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, t
23、he publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended.61156-5-2 IEC:2002(E) 3 MULTICORE AND SYMMETRICAL PAIR/QUAD CABLES FOR DIGITAL COMMUNICATIONS Part 5-2: Symmetrical pair/quad cables with transmission characteristics up to 600 MHz Horizontal floor wiring Capabi
24、lity Approval Sectional specification 1 General 1.1 Scope This part of IEC 61156 applies to Capability Approval requirements for cables for digital communications in horizontal floor wiring in accordance with generic specification IEC 61156-1-1 and Clause 4 of the sectional specification IEC 61156-5
25、 Clause 2 refers to the content of the Capability Manual. Clause 3 refers to the Quality Plans. Clause 4 is related to the maintenance of the Capability Approval. NOTE Quality assessment belongs to the negotiation between customers and manufacturers. The following clauses are intended to be a guide
26、 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 dated references, only the edition
27、 cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

29、f 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. sectional specification,
30、 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 material and dimensions, outer
31、diameter, maximum cable size and maximum cable length. c) Additional characteristics or requirements not covered by the applicable standard. 4 61156-5-2 IEC:2002(E) 2.2 Identification of the manufacturing process, equipment utilization and manufacturing instructions For each family of cables the man
32、ufacturing 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 boundaries related to ea
33、ch 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 and their related operativ
34、e instructions. 3 Quality Plan 3.1 General Reference is made to 2.2.4 of IEC 61156-1-1 with regard to process control. As a minimum, the following items shall be identified and considered: a) identification of manufacturing stages; b) identification of those characteristics which depend upon process
35、 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 Capability Qualifying Compo
36、nents (CQCs) It is necessary to point out that the manufacture of cables is composed of 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 representative sampl
37、es 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 used for the manufactur
38、e of a cable family, their corresponding purchasing specifications, and procedures for incoming inspections. 3.4 Design criteria (if applicable) The Quality Plan shall include a list of the documentation concerning the design of the cable family either directly or by reference to the manufacturers i
39、nternal instructional documents.61156-5-2 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 Approval shall be based on
40、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 61156-5-2 IEC:2002(E) Annex A (informative) Manufacturin
