This part of IEC 61 1 96 gives the general requirements and conditions for electrical tests to be performed on coaxial communication cables and applies to IEC 61 1 96-1 -1 xx (all parts), which specifies electrical test methods for coaxial communication cables.
Further test details (for example, temperature, duration) and/or test requirements are given in the relevant test procedure and/or the relevant sectional or detail specification.
A table with electrical test methods of the IEC 61 1 96-1 -1 xx series is given in Annex A.

4 Sample
4.1 Cable under test (CUT)
Unless otherwise specified in the relevant test method, the length of the CUT shall be selected to take into account the dynamic range of the measuring equipment and the frequency range specified to yield the required level of accuracy. The length should be measured with an accuracy better than 1 % unless otherwise stated in the relevant cable specification.
4.2 Pre-conditioning
The CUT shall be pre-conditioned at a constant ambient temperature for such a time as to allow the specimen temperature to stabilize according to 6.1 .
5 Tests
The tests required and performance characteristics applicable to each type of cable are given in the relevant cable standard.
6 Test conditions
6.1 Ambient conditions
Tests shall be made at:
– temperature: 1 5 °C to 35 °C,
– relative humidity: 25 % to 75 % (no condensation),
– air pressure: 86 kPa to 1 06 kPa,
unless otherwise specified.
6.2 Tolerance on temperature values
Unless otherwise specified in the relevant specification, the tolerance on temperature shall be ±2 °C.
6.3 Frequency range and stability for frequency-related measurements
The required frequency range is specified in the relevant sectional specification.
The sweep shall be linear or logarithmic such that:
where
f start is the lowest specified frequency;
f stop is the highest specified frequency;
f step is the linear frequency increment, constant over the whole specified frequency range;
n is the number of frequency points;
K is the logarithmic frequency increment.
Unless otherwise specified, the minimum number of frequency points shall be 200 per decade.
7 Test report
The test report shall include the measurements results and the actual measuring conditions with their maximum deviations.BS IEC 61196-1-100 pdf download.
