13、 required, e.g. filter and tuned circuits. Changes of capacitance and tangent of loss angle are small over the range of frequency and temperature. 4 Inspection schedule The capacitors covered by this specification shall be tested to the inspection schedule given in Table 3. This schedule gives the a
14、ppropriate tests from the schedule in 7.3.1 of BS 9070 and makes reference to the particular clauses of BS 9070:1969 which are applicable. The performance requirements to be met in the initial and final measurements of the tests in this schedule are prescribed in Table 2. 5 Ordering information When
15、 ordering parts to this detail specification the following information shall be given: 1) Capacitance value and selection tolerance. 2) Rated voltage. 3) Reference code. 4) BS number of this detail specification.
