EN ISO 13823: single burning item
EN ISO 13823 Reaction to fire tests for building products—Building products excluding floorings exposed to the thermal attack by a single burning item.
The standard similar with GB/T 20284-2006
Test principle
Consists of two wings at right angles to the vertical angle formed at the bottom of the sample exposed to the main burner flame produced by the flame produced by the burning of propane gas, propane gas burner through the sand box and generate (30.7 ± 20) kw heat output.
The combustion characteristics of the sample through the testing process 20min to Chek assessment. Performance parameters including: heat release, the amount of smoke, flame spread and burning drip lateral. Calculate the volume flow rate, heat release rate (HRR) and smoke production rate (SPR).
The testing and classification of building products EN ISO 13823 in the A2, B, C, D grading related. And A2, B, C, D grade data
A2 level in GB / T 20284 FIGRA ≤ 120W / S and LFS <edge of the sample and THR600s ≤ 7.5MJ
B grade in the GB / T 20284 FIGRA ≤ 120W / S and LFS <edge of the sample and THR600s ≤ 7.5MJ
C grade in GB / T 20284 FIGRA ≤ 250W / S and LFS <edge of the sample and THR600s ≤ 15MJ
D grade in the GB / T 20284 FIGRA ≤ 750W / S
