BS 60384-26:2010 pdf download – Fixed capacitors for use in electronic equipment Part 26: Sectional specification — Fixed aluminium electrolytic capacitors with conductive polymer solid electrolyte 2.2.5 Rated temperature The value of the rated temperature shall be upper category temperature. 3 Quality assessment procedures 3.1 Primary stage of manufacture The primary stage of manufacture is the capacitor manufacturer’s evaluation of the formed anode foil. 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 values. 3.3 Declaration of conformity (basic requirements) 3.4 Test schedule and requirement for initial assessment (mandatory and optional tests) The procedures for qualification approval testing are given in IEC 60384-1 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 Qualification approval on the basis of the fixed sample size procedures sampling The fixed sample size procedure is described in Q.5.3, b) of IEC 60384-1 . 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 detail specification. The sample shall consist of specimens of capacitors of maximum and minimum size and for each of these sizes the maximum capacitance value for the highest rated voltage and minimum rated voltage of the voltage ranges for which approval is sought. When there are more than four rated voltages, an intermediate voltage shall also be tested. Thus for the approval of a range, testing is required of either four or six values (capacitance/voltage combinations) for each temperature characteristic. Where the total range consists of less than four values, the number of specimens to be tested shall be that required for four values. In case assessment level EZ is used, spare specimens are permitted as follows: Two (for 6 values) or three (for 4 values) 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...
