EN ISO 5659-2 Plastics-Smoke generation-Part 2: Determination of optical density by a single-chamber test. EN45545-2 standard reference EN ISO 5659-2 standard for smoke density test. Tel: +0086 25 8658 3475. 

EN45545-2 Smoke density test method has four kinds, as follows:

EN45545-2 T10.01/ EN ISO 5659-2: Heat flux 50KW/M2 without pilot flame. Test duration is 10 min. Ds(4) is the optical density in the test chamber 4min into the test multiplied by a factor which depends on the instrument and on the specimen size.

EN45545-2 T10.02 EN ISO 5659-2: Heat flux 50KW/M2 without pilot flame. Test duration is 10 min. VOF4 is the cumulative value of specific optical densities in the first 4 min of the test.

EN45545-2 T10.03 EN ISO 5659-2: Ds max is the maximum optical density in the test chamber. Test duration is 10min. heat flux 25KW/M2 with pilot flame. 

EN45545-2 T10.04 EN ISO 5659-2: Ds max is the maximum optical density in the test chamber. Test duration is 10min. heat flux 50KW/M2 without pilot flame.

EN ISO 5659-2 Standard also for Toxicity testing. Gas analysis in the smoke chamber EN ISO 5659-2 using FTIR technique.(EN 45545-2:2013+A1:2015 Annex C).
