3 Terms and definitions
The terms and definitions defined in IEC 61196-1 apply to this document.
4 sample
4.1 Test Cable (CUT)
Unless otherwise specified in the relevant test methods, the length of the cable to be tested (CUT) should be selected taking into account the dynamic range of the measuring equipment and the specified frequency.
Rate range to get the required measurement accuracy. Cable length measurement accuracy should be better than 1% unless otherwise specified in the relevant cable specification.
4.2 Pretreatment
The cable under test shall be pretreated at a constant ambient temperature for a certain period of time to stabilize the temperature of the sample within the temperature range specified in 6.1.
5 test
The test and performance characteristics required for cables of different sizes are specified by the relevant cable standards.
6 Test conditions
6.1 Environmental conditions
Unless otherwise specified, the test shall be carried out in the following environments.
--- Temperature. 15 ° C ~ 35 ° C;
---Relative humidity. 25%~75% (no condensation phenomenon);
