EN 13823 (SBI)
and

D

EN 13823 (SBI)
and

FIGRA < 750 W.s^-1

(*) The treatment of some families of products, e.g. linear products (pipes, ducts, cables etc.), is still under review and may necessitate an amendment to this decision.

(1) For homogeneous products and substantial components of non-homogeneous products.

(2) For any external non-substantial component of non-homogeneous products.

(2a) Alternatively, any external non-substantial component having a PCS < 2.0 MJ.m^-2, provided that the product satisfies the following criteria of EN 13823(SBI) : FIGRA < 20 W.s^-1; and LFS < edge of specimen; and THR_600s < 4.0 MJ; and s1; and d0.

(3) For any internal non-substantial component of non-homogeneous products.

(4) For the product as a whole.

(5) s1 = SMOGRA < 30m².s^-2 and TSP_600s < 50m² ; s2 = SMOGRA < 180m².s^-2 and TSP_600s < 200m²; s3 = not s1 or s2.

(6) d0 = No flaming droplets/ particles in EN13823 (SBI) within 600s; d1 = No flaming droplets/ particles persisting longer than 10s in EN13823 (SBI) within 600s; d2 = not d0 or d1; Ignition of the paper in EN ISO 11925-2 results in a d2 classification.

(7) Pass = no ignition of the paper (no classification); Fail = ignition of the paper (d2 classification).

(8) Under conditions of surface flame attack and, if appropriate to end–use application of product, edge flame attack.

Homogen produkt: En produkt som består av ett enda material med samma densitet och sammansätt­ning i hela produkten.

Inhomogen produkt: En produkt som inte uppfyller kraven på en homogen produkt. Det är en produkt som består av en eller flera beståndsdelar, väsentliga och/eller icke väsentliga.
