    Abstract - (Show below) - (Hide below)

    Gives details of the test procedure to be used for measuring the density smoke emitted from the cables burning under defined conditions. Describes the means of assembling and preparing for test cables having an overall diameter from 2 mm upwards; gives the requirements for evaluating test results; describes the method of burning the cables.
