BS6853 Annex D.8.4 smoke density test using Panel test method

1. Standard- BS6853 Annex D.8.4
BS6853 Annex D: Methods for measuring smoke density
BS6853:1999 Code of practice for fire precautions in the design and construction of passenger carrying trains.
BS 6853 Annex D.8.4 is utilized for interior and exterior vertical surfaces and horizontal prone surfaces (Tables 2, 3, 5 and 6 of BS 6853: 1999) and seat shell (table 10 of BS6853: 1999).

2. Standard Brief-BS6853 Annex D8.4
The smoke density measurement taken from a material under fire conditions gives an indication of the visibility through the smoke, this is important as reduced visibility in a real fire situation makes it more difficult to escape from a fire hence increasing the threat to human life from the toxic gases, flames and heat.
