This International Standard provides a range of tests which may be required for electric cables which have an extruded oversheath and where that oversheath performs a special protective function.
NOTE 1 The need for the special functions may be independent of the nature of the insulation type or independent of the rated voltage of the cable.
The standard covers cables for use in insulated systems and in uninsulated systems.
The tests are categorized for use as
a) routine tests, b) type tests, c) tests after installation. These tests comprise:
- electrical routine tests on cable oversheath used in insulated or uninsulated systems, - abrasion and corrosion spread type tests, - electrical test on cable oversheath after installation. Routine tests and tests after installation, as specified in the relevant cable standards, are applicable for all situations.
Type tests depend upon the nature of the system and the construction of the cable and do not have to be carried out for normal conditions of use.
The application of the abrasion test is given in Annex A.
NOTE 2 Guidance on tests after installation is given in Annex B.
