4 Conditions of use

4.1 Normal use conditions This section gives requirements for capacitors to be used under the following conditions. a) Altitude. no more than.2000m. b) Residual voltage on the capacitor when voltage is applied. should not exceed 10% of the rated voltage (see Note to 7.4). c) Contamination. Capacitors included in the scope of this section are designed to operate in a slightly polluted atmosphere. Note. The definition of “light contamination” has not been determined by the IEC . Once the IEC has defined this definition, it will be included in this section. d) Operating temperature. between -40 ° C and 100 ° C (see 3.10 and 3.11). The preferred minimum and maximum allowable capacitor operating temperatures are as follows. ---Minimum temperature. -40 ° C, -25 ° C, -10 ° C and 0 ° C; --- Maximum temperature. 55 ° C, 70 ° C, 85 ° C and 100 ° C. Capacitors shall be suitable for transport and storage at temperatures as low as -25 ° C or at the lowest operating temperature (whichever is lower), without adversely affecting their quality Impact. e) Damp heat severity. between 4 days and 56 days, the priority severity is 21 days. (Damp heat severity should be selected from the values listed in IEC 60068-2-78, ie. 4 days, 10 days, 21 days, and 56 days). Capacitors are classified by climate category, and each climate category is expressed in terms of minimum and maximum allowable capacitor operating temperatures and wet heat severity. That is, 10/70/21 means that the minimum and maximum allowable capacitors operate at -10 ° C and 70 ° C, and the wet heat severity is 21 days. 4.2 Priority capacitance deviation The preferred capacitance deviation is. ± 5%, ± 10% and ± 15%. Asymmetric deviations are allowed, but the deviation must not exceed 15%.

5 Quality requirements and tests

For calibration, the reference temperature should be 20 °C. Note. If the capacitor is placed in a state where no voltage is applied and is placed in this ambient temperature for a sufficient period of time (depending on the size of the capacitor), then It can be considered that the medium temperature is the same as the ambient temperature. 5.2 Types of tests The test is divided into two categories. a) type test; b) Routine tests. 5.2.1 Type test Type testing is used to verify the rationality of the capacitor design and its suitability for operation under the conditions specified in this section. The type test is carried out by the manufacturer and is carried out by an authoritative inspection agency if certification is required. Type testing can also be carried out under the supervision of an authority that issues certification reports or type approvals. 5.2.2 Routine test Routine tests shall be performed by the manufacturer for each capacitor prior to delivery. A routine test report should be provided when requested by the purchaser. 5.3 Type test 5.3.1 Test procedure The samples of each type selected for the type test shall be divided into the groups shown in Table 1. The capacitor used as the test sample has successfully passed the routine test shown in 5.4.1. Each test group shall contain a capacitor with an equal number of maximum capacitances and minimum capacitances in the range. The manufacturer shall provide data on the ratio of the ratio of each capacitor in its range to the total external surface area of the enclosure. If the ratio exceeds the ratio of the maximum capacitance in the range by 10% or more, the capacitor having the largest unit surface area capacitance is also Should be tested. Again, like.
