16、 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 by the harmonization of the specif

17、ications and quality assessment procedures for electronic components, and by the grant of an internationally recognized Mark, or Certificate, of Conformity. The components produced under the System are thereby acceptable in all member countries without further testing. This specification was prepare

18、d by CECC WG16, Relays. The text of the draft based on document CECC (Secretariat)2826 was submitted to the formal vote; together with the voting report, circulated as document CECC (Secretariat)3143, it was approved by CECC as EN116300 on10 August 1992.

Scope This sectional specification applies to electromechanical all-or-nothing heavy load relays of assessed quality, rated from5A and above. It selects from the generic specification EN116000-1:1992 (CECC16000-1:1990) and

23、other sources the appropriate methods of tests to be used in detail specifications derived from this specification, and contains basic test schedules to be used in the preparation of such specifications. Detailed test schedules are contained in the blank detail specifications supplementary to this s

24、pecification. Section 2. General 2.1 Related documents Section 3. Quality assessment procedures 3.1 Primary stage of manufacture The primary stage of manufacture is the assembly of the electromotive part of the relay to the electric switching part of the relay. 3.2 Structurally similar relays Relays

25、 are considered structurally similar if having no other differences in design than in: 1) coil wire diameter, number of windings and coil suppression devices 2) types and numbers of contacts 3) rated coil and/or contact voltage(s) 4) mounting and terminal variants 3.3 Subcontracting Preliminaries fo

26、r subcontracting are as in CECC00114-II1.2 3.4 Qualification approval procedures Qualification approval tests shall include all the tests prescribed in the detail specification, and shall be performed by a schedule specifically prescribed in the detail specification. The number of specimens for each

27、 sub-group is to bespecified in the blank detail specification. The qualification test schedule shall indicate those considered to be destructive or non-destructive tests. 3.5 Quality conformance inspection 3.5.1 Formation of inspection lots Inspection lots submitted to group A acceptance tests shal

28、l be formed in accordance with section3.1 of CECC00114-II and with the sampling plans and procedures given in IEC Publication410, except where production is too infrequent or too small for sampling plans to apply; in these cases inspection shall be100%, or as agreed between the manufacturer, the ONS

29、 and when known, the ultimate user. When sampling is carried out in accordance with IEC Publication410, the percent defective concept only shall be used. Stratified or representative sampling shall always be used to include all production lines and structurally similar relays in proportion to their

30、respective quantities in the lot. Exceptions from proportionality may become necessary and shall be stated in the detail specification. Specimens shall be as representative as possible of the production. CECC00114-II:1991 Quality Assessment Procedures. Part II: Qualification approval for electronic

32、ion shall be taken from a lot (or lots) which has (have) passed group A inspection during, or at the end of the specified reference period. In both cases the inspection lot (or lots) shall not be less than the average of production lots during the reference period for each group. 3.6 Test schedule 3

33、.6.1 Test sequence A test sequence shall consist of all tests listed in the detail specification. Where appropriate, the reference numbers of the tests are those of EN116000-1:1992 (CECC16000-1:1990) Generic Specification, Electromechanical all-or-nothing relays. 3.6.2 Group A The Inspection Level (

34、IL) notation applies to all tests in one sub-group. A corresponding value/range of values of the Acceptable Quality Level (AQL) shall be given in the blank detail specification, and the authority preparing detail specifications shall choose the appropriate value, which then applies to all tests in o

35、ne sub-group. Any given IL AQL notations shall be interpreted such that the number of defectives allowable for acceptance is applicable to each test within a sub-group separately. However, the blank detail specification may prescribe this same IL for relays submitted to cumulative tests of the same

36、sub-group. 3.6.3 Groups C and D The blank detail specification shall prescribe for each sub-group: 1) Periodicity of each sub-group. 2) The minimum sample size for each test (or group of tests) performed with the same relays and acceptable number of defectives. 3.7 Order of tests Quality conformance

37、 inspection is divided into two parts: that carried out lot by lot, on which the release of the individual lot is based, and that carried out on a periodic basis, which contains the time-consuming and more expensive tests. When several tests are subsequently to be carried out on any one specimen or

38、number of specimens, the following order shall apply unless otherwise prescribed in the blank detail specification: Sub-group A 0 and screening (if applicable) shall always precede any other test. The remaining tests shall be performed as given in the detail specification. Destructive (D) tests may

39、be preceded by one or more ND or D tests, provided that the effects of the preceding tests are not considered liable to invalidate the results of the later tests. The order of tests in each sub-group is mandatory. The following tests shall be carried out for screened and unscreened relays. Assessmen

Preparation of blank detail and detail specifications 4.1 Blank detail specifications shall conform to the test schedules given in section5 of

41、 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 of the detail specification 2) Identification of the relay and information on its applications. Identifica

42、tion shall be provided by such properties as switching power, size, sealing, whether monostable or bistable, polarised or not, or other characteristics required for identification, contact operating range and temperature range. 3) Outline drawings of the relay and key dimensions. Variants, such as f

43、or terminations, may be given in an appendix to the detail specification. 4) Reference data of the relay a) A limited number of characteristic values is required on the front page to describe the overall performance of the relay. b) Full information in conformance with IEC-Publication255-1-00 shall

44、be added on one of the subsequent pages. Rated values should preferably be those listed therein. 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 distinguished from th

45、e rated values. 5) Related documents Reference shall be made to CECC16000 and this sectional specification.
