16、tronic Components Committee (CECC) is composed of those member countries of the European Committee for Electrotechnical Standardization (CENELEC) who wish to take part in a harmonized System for electronic components of assessed quality. The object of the System is to facilitate international trade
17、by the harmonization of the specifications and quality assessment procedures for electronic components, and by the granting of an internationally recognized Mark, or Certificate, of Conformity. The components produced under the System are thereby acceptable in all member countries without further te
18、sting. This specification was prepared by CECC WG16 Relays. The text of the draft based on document CECC (Secretariat)2781 was submitted to the formal vote; together with the voting report, circulated as document CECC(Secretariat)3141, it was approved by CECC as EN147100 on10 August1992.

22、y. It selects from the generic specification EN147000:1993 and other sources the appropriate methods of test to be used in detail specifications derived from this specification, and contains basic test schedules to be used in the preparation of such specifications. 2 General 2.1 Related documents 3
23、Quality assessment procedures 3.1 Primary stage of manufacture The primary stage of manufacture is the molding of insulation body as well as assembly of parts other than contact and removable hardware. 3.2 Structurally similar sockets Sockets are considered structurally similar if having no other di
24、fferences in design than in: 1) Insulating material 2) Type, number and material of contacts 3) Rated current of continuous service 4) Mounting and terminal variants within limits prescribed in the detail specifications 3.3 Qualification approval tests Qualification approval tests shall include all
25、the tests prescribed in the detail specification, and shall be performed by a schedule specifically prescribed in the detail specification (1.4, method1, of CECC00114-II). As a general rule, a minimum of five specimens are required for each group of test. Samples submitted to non-destructive tests m
26、ay be used for subsequent destructive tests. 3.4 Quality conformance inspection 3.4.1 Formation of inspection lots Inspection lots submitted to group A and B acceptance tests, shall be formed in accordance with3 of CECC00114-II and with the sampling plans and procedures given in IEC410, except where
27、 production is too infrequent or too small for sampling plans to apply; in these cases inspection shall be100%. When sampling is carried out in accordance with IEC410, the percent defective concept only shall be used. Stratified or representative sampling shall always be used to include all producti
28、on lines and structurally similar sockets in proportion to their respective quantities in the lot. 3.4.2 Periodic inspection Fixed samples for group C inspection shall be taken from a lot (or lots) which have passed group A inspection during, or at the end of, the specified reference period. 3.5 Tes
29、t schedule 3.5.1 Test sequence A test sequence shall consist of all tests listed in the detail specification in prescribed order. Where appropriate, the reference numbers of the tests are those of EN147000:1993 Generic specification. Additional testing may be called for by the detail specification.
30、3.5.2 Group A and B The Inspection Level (IL) notation applies for all tests in one sub-group. Any given IL and/or AQL notations shall be interpreted such that the number of defectives allowable for acceptance is applicable to each test within a sub-group separately. 3.5.3 Group C The blank detail s
31、pecification shall prescribe for each sub-group: 1) Periodicity of each sub-group. If the same periodicity is applicable to all sub-groups, it shall be given at the beginning of the group test details. 2) The minimum sample size for each test (or group of tests). 3) The permitted number of defective
32、 samples. 3.6 Order of tests 3.6.1 Quality conformance inspection is divided into two parts: that carried out lot-by-lot on which the release of the individual lots is based, and that carried out on a periodic basis which contains the time-consuming and more expensive tests.

35、number of specimens, the following order shall apply, unless otherwise prescribed in the detail specification. 1) Group A: tests shall always precede any other non destructive (ND) or destructive (D) tests. 2) ND tests shall be conducted in a suitable sequence provided that the effects of the preced
36、ing tests are not considered liable to invalidate the results of the later tests. 3) Destructive tests may be preceded by one or more ND tests, provided that the effects of the preceding tests are not considered liable to invalidate the results of the later tests. 4 Writing of blank detail and detai
37、l specifications 4.1 Blank detail specifications shall conform with the test schedules given in Table 1 of this specification and the related explanations. 4.2 Blank detail specifications shall give the following information or call for its inclusion into the detail specification: 1) Identification
38、of the detail specification 2) Identification of the socket and information on its applications Identification shall be provided by such properties as reference to one relay, size and number of contacts, all other information necessary for identification. 3) Outline drawing of the socket and key dim
39、ensions Variants, such as for terminations, may be given in an appendix to the detail specification. 4) Reference data A limited number of values are required on the front page, so as to describe the overall performance of the socket. Full information in conformance with IEC255-1-00 shall be added o
40、n one of the subsequent pages. Rated values should preferably be those listed in IEC255-1-00 where applicable. Where tests refer to rated values, they shall be indicated with each test. Where tests are to be performed at other than rated values, the test values shall be indicated and clearly disting
41、uished from the rated values. 5) Related documents Reference shall be made to EN147000:1993 and this sectional specification. When reference to further documents is necessary, such documents shall be listed with their full titles, year of edition and, unless common knowledge, the source from which t
