Quality assessment procedures 3.1 Primary Stage of Manufacture The primary stage of manufacture is the forming of the oxide. 3.2 Structurally Similar Components Capacitors considered as being structur

24、ally similar are capacitors produced with similar processes and materials, though they may be of different case sizes and values. 3.3 Certified Records of Released Lots The information required in Sub-clause 3.5.1 of I E C Publication 384-1 shall be made available when prescribed in the detail speci

25、fication and when requested by a purchaser. After the endurance test, the parameters for which variables information is required are the capacitance change, tan and the leakage current. EEEIA-60384-15 Page 8 3.4 Qualification Approval The procedures for Qualification Approval testing are given in Su

26、b-clause 3.4 of the Generic Specification, I E C Publication 384-1. The schedule to be used for Qualification Approval testing on the basis of lot-by-lot and periodic tests is given in Sub-clause 3.5 of this specification. The procedure using a fixed sample size schedule is given in Sub-clauses 3.4.

27、1 and 3.4.2 below. 3.4.1 Qualification Approval on the basis of the fixed sample size procedures Sampling The fixed sample size procedure is described in I E C Publication 384-1, Sub-clause 3.4.2 b). The sample shall be representative of the range of capacitors for which approval is sought. This may

28、 or may not be the complete range covered by the detail specification. The sample shall consist of specimens having the lowest and highest voltages, and for these voltages the smallest and largest case size. When there are more than four case sizes an intermediate case size shall also be tested. In

29、each of these case size/voltage combinations (values) the highest capacitance shall be chosen. Thus for the approval of a range, testing is required of either four or six values. When the range consists of less than four values, the number of specimens to be tested shall be that required for four va

30、lues. Spare specimens are permitted as follows: a) One per value which may be used to replace the permitted defective in Group “0“. b) One per value which may be used as replacements for specimens which are defective because of incidents not attributable to the manufacturer. The numbers given in Gro

31、up “0“ assume that all groups are applicable. If this is not so the numbers may be reduced accordingly. When additional groups are introduced into the Qualification Approval test schedule, the number of specimens required for Group “0“ shall be increased by the same number as that required for the a

32、dditional groups. Table I gives the number of samples to be tested in each group or sub-group together with the permissible number of defectives for qualification approval tests. 3.4.2 Tests The complete series of tests specified in Tables I and II are required for the approval of capacitors covered

33、 by one detail specification. The tests of each group shall be carried out in the order given. The whole sample shall be subjected to the tests of Group “0“ and then divided for the other groups. Specimens found defective during the tests of Group “0“ shall not be used for the other groups. “One def

34、ective“ is counted when a capacitor has not satisfied the whole or a part of the tests of a group. EIA-60384-15 Page 9 The approval is granted when the number of defectives does not exceed the specified number of permissible defectives for each group or sub-group and the total number of permissible

35、defectives. Note.- Tables I and II together form the fixed sample size test schedule, for which Table I includes the details for the sampling and permissible defectives for the different tests or groups of tests, whereas Table II together with the details of test contained in Section Four gives a co

36、mplete summary of test conditions and performance requirements and indicates where e.g. for the test method or conditions of test a choice has to be made in the detail specification. The conditions of test and performance requirements for the fixed sample size test schedule shall be identical to tho

37、se prescribed in the detail specification for quality conformance inspection. TABLE I Sampling plan together with numbers of permissible defectives for qualification approval tests 1) If prescribed in the detail specification. 2) Not more than one defective is permitted from any one value. 3) As pre

38、scribed in the detail specification. 4) Case size/voltage combinations, see Sub-clause 3.4.1. EEEIA-60384-15 Page 10 TABLE II Test schedule for Qualification Approval Notes 1.- Sub-clause numbers in this schedule refer to Section Four: Test and measurement procedures. 2.- In this table: D = destruct

39、ive, ND = non-destructive.

A manufacturer may aggregate the current production into inspection lots subject to the following

41、 safeguards: (1) The inspection lot shall consist of structurally similar capacitors (see Sub-clause 3.2). (2a) The sample tested shall be representative of the values and dimensions contained in the inspection lot: - in relation to their number; - with a minimum of five of any one value. (2b ) If t

42、here are less than five of any one value in the sample the basis for the drawing of samples shall be agreed between the manufacturer and the National Supervising Inspectorate. b) Group C inspection These tests shall be carried out on a periodic basis. Samples shall be representative of the current p

43、roduction of the specified periods and shall be divided into high, medium and low voltage ratings or case sizes. In order to cover the range of approvals in any period, one high, one medium and one low voltage or case size shall be tested. In subsequent periods other voltages or case sizes in produc

44、tion shall be tested with the aim of covering the whole range. EIA-60384-15 Page 17 3.5.2 Test schedule The schedule for the lot-by-lot and periodic tests for Quality Conformance Inspection is given in Section Two, Table IV of the Blank Detail Specification, I E C Publications 384-15-1, 384-15-2 or

46、n the blank detail specification shall preferably be selected from Tables III A and III B: TABLE III A IL = inspection level AQL = acceptable quality level TABLE III B p = periodicity in months n = sample size c = permitted number of defectives Notes concerning Tables III A and III B: * The assessme

47、nt levels D, F and G are under consideration. * The content of the Inspection sub-groups is described in Section Two of the relevant blank detail specification.
