2、ING DEPARTMENT NOTICE 1 EIA Engineering Standards and Publications are designed to serve the public interest through eliminating misunderstandings between manufacturers and purchasers, facilitating interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining

3、 with minimum delay the proper product for his particular need. Existence of such Standards and Publications shall not in any respect preclude any member or non- member of EIA from manufacturing or selling products not conforming to such Standards and Publications, nor shall the existence of such St

4、andards and Publications preclude their voluntary use by those other than EIA members, whether the standard is to be used either domestically or internationally. Recommended Standards and Publications are adopted by EIA without regard to whether their adoption may involve patents on articles, materi

5、als, or processes. By such action, IA does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the Recommended Standard or Publication. This EIA Specification is considered to have International Standardization implication, but the Internation

6、al Electrotechnical Commission activity has not progressed to the point where a valid comparison between the EIA Specification and the IEC document can be made. This Specification does not purport to address all safety problems associated with its use or all applicable regulatory requirements. It is

7、 the responsibility of the user of this Specification to establish appropriate safety and health practices and to determine the applicability of regulatory limitations before its use.

30、e. gualification amroval The procedures for qualification approval testing are given in Subclause 3.4 of the generic specification, IEC 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 Subclause 3.5 of this specif

31、ication. The procedure using a fixed sample size schedule is given in Subclauses 3.4.1 and 3.4.2 below. For the two procedures the sample sizes and the number of permissible defectives shall be of comparable order. The test conditions and requirements shall be the same. 3.4.1 ualification ammoval on

32、 the basis of fixed sample size procedures. SamDlinq The fixed sample size procedure is described in Subclause 3.4.2 b) of IEC Publication 384-1. The sample shall be representative of the range of capacitors for which approval is sought. This may or may not be the complete range covered by the detai

33、l specification. t EIA-580A000 Page 9 The sample shall consist of specimens having the lowest and highest voltages, and for these voltages the lowest and highest capacitances. When there are more than four rated voltages an intermediate voltage shall also be tested. Thus for the approval of range, t

34、esting is required of either four or six values (capacitance/voltage combinations) . When the range consists of fewer than four values, the number of specimens to be tested shall be that required for four values. Spare specimens are permitted as follows: a) One per value, which may be used to replac

35、e the permitted defective in Group lfO1g. 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 Group lfO1f assume that all groups are applicable. If this is not so the numbers may be red

36、uced accordingly. When additional groups are introduced into the qualification approval test schedule, the number of specimens required for Group flO1l shall be increased by the same number as that required for the additional groups. Table 1 gives the number of samples to be tested in each group or

37、subgroup together with the permissible number of defectives for qualification approval tests. 3.4.2 Tests The complete series of tests specified in Tables 1 and 2 are required for the approval of capacitors covered by one detail specification. The tests of each group shall be carried out in the orde

38、r given. The whole sample shall be subjected to the tests of Group lfO1f and then divided for the other groups. Specimens found defective during the tests of Group llOff shall not be used for the other groups. !One defective11 is counted when a capacitor has not satisfied the whole or a part of the

39、tests of a group. EIA 580A000 92 3234600 055b307 030 = EIA-580A000 Page 10 The approval is granted when the number of defectives does not exceed the specified number of permissible defectives for each group or subgroup and the total number of permissible defectives. Note: Tables 1 and 2 together for

Table 2, together with the details of test contained in Section Four, gives a complete summary of test conditions and performance requirements a
