IEC 61034-2 Ed. 3.2 b – Measurement of smoke density of cables burning under defined conditions – Part 2: Test procedure and requirements CONSOLIDATED EDITION

IEC 61034-2:2019 Provides details of the test procedure to be employed for the measurement of the density of smoke emitted from cables burning under defined conditions. It describes the means of preparing and assembling cables for test, the method of burning the cables, and gives recommended requirements for evaluating test results. The principal changes with respect to the previous edition are as follows:
a) inclusion of cables down to 1 mm diameter;
b) inclusion of non-circular cables;
c) addition of guidance on testing cables above 80 mm diameter;
d) delineation of elements of the test report;
e) addition of guidance on the calculation for other parameters for fire safety engineering purposes;
f) removal of minor differences with equivalent CENELEC work to allow parallel voting with that body. Has the status of a group safety publication in accordance with IEC Guide 104.
