Extent: E+W+S+N.I.

Table 1
Classes of reaction to fire performance for construction products excluding floorings, linear pipe thermal insulation products, and electric cables
For homogeneous products and substantial components of non-homogeneous products.
For any external non-substantial component of non-homogeneous products.
(2a) Alternatively, any external non-substantial component having a PCS ≤ 2,0 MJm– 2, provided that the product satisfies the following criteria of EN 13823(SBI): FIGRA ≤ 20 Ws– 1; and LFS < edge of specimen; and THR600s ≤ 4,0 MJ; and s1; and d0.
For any internal non-substantial component of non-homogeneous products.
For the product as a whole.
s1 = SMOGRA ≤ 30m2s– 2 and TSP600s ≤ 50m2; s2 = SMOGRA ≤ 180m2s– 2 and TSP600s ≤ 200m2; s3 = not s1 or s2.
d0 = No flaming droplets/particles in EN 13823 (SBI) within 600s; d1 = No flaming droplets/particles persisting longer than 10s in EN 13823 (SBI) within 600s; d2 = not d0 or d1; Ignition of the paper in EN ISO 11925-2 results in a d2 classification.
No ignition of the paper = no additional classification; Ignition of the paper = d2 classification.
Under conditions of surface flame attack and, if appropriate to the intended use of the product, edge flame attack.

Classes of reaction to fire performance for floorings

For any external non-substantial component of non-homogeneous products.
For any internal non-substantial component of non-homogeneous products.

Test duration = 30 minutes.
Critical flux is defined as the radiant flux at which the flame extinguishes or the radiant flux after a test period of 30 minutes, whichever is the lower (i.e. the flux corresponding with the furthest extent of spread of flame).
s1 = Smoke ≤ 750 %.min; s2 = not s1.
Under conditions of surface flame attack and, if appropriate to the intended use of the product, edge flame attack.
