3 Quality assessment procedures
3.1 Primary stage of manufacture

The primary stage of manufacture is the forming of the tantalum oxide dielectric.

3.2 Structurally similar components

Capacitors considered as being structurally similar are capacitors produced with similar processes and materials, though they may be of different case sizes and capacitance and voltage values.

3.3 Certified test records

The information required in 3.9 of EN 130000 shall be made available when prescribed in the detail specification and when requested by a purchaser.

After the endurance test the parameters for which variables information is required are the capacitance change, tangent of loss angle and the leakage current.

3.4 Qualification approval

The procedures for qualification approval testing are given in 3.5 of the generic specification EN 130000.

The schedule to be used for qualification approval testing on the basis of lot-by-lot and periodic tests is given in 3.5 of this specification.

The procedure using a fixed sample size schedule is given in 3.4.1 and 3.4.2 below.

3.4.1
Sampling

The fixed sample size procedure is described in 3.5.3(2) of EN 130000. 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 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 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 values.

SIST EN 130800:2002
Page 9 EN 130800:2000 Spare specimens are permitted as follows:
(1)

0ne per value which may be used to replace the permitted non-conforming items in Group 0.

(2)

0ne per value which may be used as replacements for specimens which are non-conforming because

of incidents not attributable to the manufacturer.

The numbers given in Group 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 additional groups.

Table A.1 or B.1 gives the number of samples to be tested in each group or sub-group together with the permissible number of non-conforming items for qualification approval tests.

3.4.2
Tests

The complete series of tests for selected assessment level given in Tables A.1 to A.3, respectively in Tables B.1 to B.3 and the test schedule given in annex C are required for the approval of capacitors covered 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.

Non-conforming specimens found during the tests of Group 0 shall not be used for the other groups.

"0ne non-conforming item" is counted when a capacitor has not satisfied the whole or a part of the tests of a group.

The approval is granted when the number of non-conforming items does not exceed the specified number of permissible non-conforming items for each group or sub-group and the total number of permissible non-conforming items.

NOTE 1

Table A.1 and Table C.1 or Table B.1 and Table C.1 together form the fixed sample size test schedule.

Annex A or B includes the details for the sampling and permissible non-conforming items for the different tests or groups of tests whereas annex C together with the details of test contained in clause 4 give a complete summary of test conditions and performance requirements indicate where, for example for the test method or conditions of test, a choice has to be made in the detail specification.

NOTE 2

The conditions of test and performance requirements for the fixed sample size test schedule shall be identical to those prescribed in the detail specification for quality conformance inspection.

3.5 Quality conformance inspection
3.5.1
Formation of inspection lots
3.5.1.1
Groups A and B inspection

These tests shall be carried out on a lot-by-lot basis according to test plan for selected assessment level in Table A.2 or B.2.

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

(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
SIST EN 130800:2002

Page 10 EN 130800:2000 (2b) If there 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.

3.5.1.2
Group C inspection

These tests shall be carried out on a periodic basis according to the test plan for selected assessment level in Table

A.3 or B.3.

Samples shall be representative of the current production of the specified periods and shall be divided into small, medium and high sizes.

In order to cover the range of approvals in any period one voltage shall be tested from each group of sizes.

In subsequent periods other sizes and/or voltage ratings in production shall be tested with the aim of covering the whole range of approval.

3.5.2
Test schedule
The test schedule for qualification approval is given in annex C.
