BS EN 61034-1:2005+A2:2020

This standard BS EN 61034-1:2005+A2:2020 Measurement of smoke density of cables burning under defined conditions is classified in these ICS categories:

• 29.060.20 Cables
• 29.020 Electrical engineering in general
• 13.220.40 Ignitability and burning behaviour of materials and products

This part ofIEC 61034 provides details of the test apparatus to be used for measuring smoke emission when electric or optical fibre cables are burnt under defined conditions, for example, a few cables burnt horizontally. The light transmittance (l_t) under flaming combustion and smouldering conditions can be used as a means of comparing different cables or complying with specific requirements.

NOTE For the purposes of this standard, the term "electric cable" covers all insulated metallic conductor cables used for the conveyance of energy or signals.
