Smoke density

How is smoke density measured?

In case that cables burn smoke develops that may for example impede the rescue of persons in the fire zone. The smoke density is tested acc. to standard IEC 61034 (DIN EN 61034, VDE 0482-1034). The test is executed in a defined room size by fixing the cables over a tub filled with burning alcohol. The light transmission between the lamp and a photocell is not allowed to be subdued more than a prescribed value during the test period.
