3 General cable specifications
3.1 Cable classes
Depending on the test temperature for the thermal overload test (see 4.9) six cable classes are specified. See Table 1.
3.2 Cable types
The type of cable depends on the conductor used. See Table 2.
4 Tests and requirements
4.1 General test conditions
Unless otherwise specified:
— all tests shall be performed at an ambient temperature (room temperature) of (23 ± 5) °C;
— each test shall be started with an unused sample.
Samples for all tests shall be preconditioned for at least 16 h at room temperature.
When an oven is required. it shall be a hot air oven. The air contained in the oven shall be comp’etely changed at least eight times per hour, but not more than 20 times per hour, at the specified temperature.
4.2 Cable dimensions
4.2.1 Measurements
The outside diameter of the cable shall be determined by taking five sets of measurements along a 1 m length of the cable. Each set of measurements shall consist of the determination of the maximum and minimum diameters at the point of measurement.
4.2.2 Requirement
No single value shall be outside the tolerance given in 3.3.
4.3 Cable resistance
4.3.1 Measurement
The standard sample shall be 1 m in length, plus a stripped length necessary for connections. Other lengths may be used, provided that the resistance reading is adjusted using the procedure given in 4.3.3.
4.3.2 Resistance measuring device
The accuracy of the resistance measuring device shall be ± 0,5 % of the measured value.ISO 3808 pdf download.
