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 sp
