EN 50268-2/EN45545-2 cable smoke density--Standard

EN 50268-2:2002 Common test methods for cables under fire conditions-Measurement of smoke density of cables burning under defined conditions-Part 2: Procedure.

EN 61034-2: Measurement of smoke density of cables burning under defined conditions---Part 2: Test procedure and requirement. EN 61034-2:2005 is identical with IEC 61034-2:2005.It supersedes EN 50268-2:2002 which is withdrawn.

Smoke density test is the combustion of an important aspect of performance evaluation, as it relates to the degree of difficulty for personnel evacuation.


EN 50268-2/EN45545-2 cable smoke density--Test method

Cable requirements straight, before testing the temperature 23 ¡æ ¡À 5 ¡æ placed under 16 hours in advance.

Experimental test time is 40 minutes, smoke density test by the lowest rate of light transmission


EN 50268-2/EN45545-2 cable smoke density¡ªScope
The European standard EN45545-2 R14 (interior for cable testing), R15 (exterior for cable testing) reference EN50268-2 electric wire & cable smoke density test.

According to the level of risk of running vehicles, EN45545-2 standard on the numerical density of smoke wire and cable are different.
