Table B1 Reaction to fire classifications: transposition to national class

BS 476-11
BS 476-7
NOTE:
The national classifications do not automatically equate with the transposed classifications in the ‘BS EN 13501-1 classification’ column, therefore products cannot typically assume a European class unless they have been tested accordingly.
NOTE:
A classification of s3, d2 indicates that no limit is set for production of smoke and/or flaming droplets/particles. If a performance for production of smoke and/or flaming droplets/ particles is specified, then only the European classes can be used. For example, a national class may not be used as an alternative to a classification which includes s1, d0.
