1.1 General requirements
The methods of carrying out the tests specified in all parts of IEC 60227 are given in this part and the following publications:
IEC 60227-1: 1993, Polyviny chloride insulated cables of rated voltages up to and including 450/750V-Part 1: General requirements;
IEC 60332-1: Tests on electric cables under fire conditions-Part 1: Test on a single vertical;
IEC 60811-1-1: 1993, Common test methods for insulating and sheathing materials of electrical cables-Part 1: Methods for general application-Section 1: Measurement of thickness and overall dimensions- Test for determining the mechanical properties.
1.4 Sampling
If a marking is in relief in the insulation or sheath, the samples used for the tests shall be taken so as to include such marking.
For multicore cables, except for the test specified in 1.9, not more than three cores (of different colours, if applicable) shall be tested unless otherwise specified.
All the tests shall be carried out not less than 16 h after the extrusion of the insulating or sheathing compounds.
1.6 Test temperature
Unless otherwise specified, tests shall be made at ambient temperature.
