NOTE - The requirements and tolerances permitted by this standard are related to testing of a type test sample su
24、bmitted for that purpose. In principle, this type test sample should consist of units having charac- teristics typical of the manufacturerfs pioduction and be as close to the production centre points as possible. It may be expected with the tolerances given in the standard that products manufactured
25、 in accordance with the type test sample will comply with the standard for the majority of the production. Due to the production spread, it is inevitable, however, that there may be pro- ducts outside the specified tolerances. For guidance on sampling plans and procedures for inspection by attribute

Unless otherwise specified, tests shall be carried out at a temperature of 20 OC f 5 OC, using where appropriate a voltage source as detailed in annex B. Test temperatures
27、specified in particular clauses shall be subject to a tolerance of +2 OC, unless otherwise stated. Unless otherwise specified, the type shall be deemed to comply with any one clause if not more than one failure occurs in the test of that clause. If three or more failures occur, the type shall be rej
28、ected. If two failures occur in any one test, that test, and any preceding tests which may have influenced the test results, shall be repeated on the same quantity of capacitors and if any further failures occur, the type shall be rejected. For a range of capacitors of the same construction, rated v

Moreover, the manufacturer shall provide data on the ratio of capacitance per area outer total sur
30、face of the container of each capacitance value in the range. The capacitor with the maximum capacitance per unit surface area shall also be tested if this ratio exceeds that of the maximum capacitance value in the range by 10 % or greater. Simllarly, the capacitor with the minimum capacitance per u
31、nit area shall also be tested if the ratio is less than that of the minimum capacitance value in the range by 10 % or greater. “Area“ denotes total outer surface area of capacitor case ignoring small protrusions, terminals and flxlng studs.
