    Abstract - (Show below) - (Hide below)

    EN 50268 specifies a method of test for measurement of smoke density of cables burning under defined conditions. It is suitable for electric insulated conductor or cable, or optical cables. This Part 1 details the apparatus. The procedure, together with an Informative Annex of recommended requirements for compliance, is given in Part 2. NOTE: Experience has shown that the test protocol is not suitable for some cables that exceed 70 mm overall diameter. In such cases the manufacturer should be consulted
