Construction products regulation classification

The Euroclass Table defines seven classes (Aca, B1ca, B2ca, Cca, Dca, Eca and Fca) based on their fire reaction, such as heat release and flame spread/propagation.

 

In this classification, heat release and flame spread/propagation are the main classification criteria, but a series of additional criteria is also defined. Those additional criteria apply only to classes B1ca, B2ca, Cca and Dca and they regard:

 

Criteria Definitions
smoke
SMOKE PRODUCTION

Smoke opacity: s1, s1a, s1b, s2 and s3 – s1 corresponding to the best performance and s3 the least.

droplets
FLAMING DROPLETS
d0, d1 and d2 – d0 corresponding to the best performance and d2 the least
acidity
ACIDITY

a1, a2, a3 during fire – a1 corresponding to the best performance and a3 the least

 

The smoke classes s1a and s1b reflect requirements that have been in use for a long time in Europe. The acidity classes do also have a background in long traditions.
