ANNEX
Classes of reaction to fire performance
1.1.
For the purposes of Tables 1 to 4 the following symbols  ( 1 ) apply:
(1)    ‘ΔΤ’ — temperature rise;
(2)    ‘Δm’ — mass loss;
(3)    ‘t f ’ — duration of flaming;
(4)    ‘PCS’ — gross calorific potential;
(5)    ‘LFS’ — lateral flame spread;
(6)    ‘SMOGRA’ — smoke growth rate.
1.2.
For the purposes of Tables 1, 2 and 3 the following symbols  ( 1 ) apply:
(1)    ‘FIGRA’ — fire growth rate;
(2)    ‘THR’ — total heat release;
(3)    ‘TSP’ — total smoke production;
(4)    ‘Fs’ — flame spread.
1.3.
For the purposes of Table 4 the following symbols and test parameters apply:
(1)    ‘HRR sm30 , kW’ — heat release rate averaged by a 30-s sliding average;
(2)    ‘SPR sm60 , m 2 /s’ — smoke production rate averaged by a 60-s sliding average;
(3)    ‘Peak HRR, kW’ — maximum of HRR sm30 between test start and end of test, excluded contribution from ignition source;
(4)    ‘Peak SPR, m 2 /s’ — maximum of SPR sm60 between test start and end of test;
(5)    ‘THR 1200 , MJ’ — total heat release (HRR sm30 ) from test start until end of test, excluded contribution from ignition source;
(6)    ‘TSP 1200 , m 2 ’ — total smoke production (HRR sm60 ) from test start until end of test;
(7)    ‘FIGRA, W/s’ — fire growth rate index defined as the highest value of the quotient between HRR sm30 excluding the contribution of ignition source and time. Threshold values HRR sm30  = 3 kW and THR = 0,4 MJ;
(8)    ‘FS’ — flame spread (damaged length);
(9)    ‘H’ — flame spread.
2.
For the purposes of Tables 1 to 4 the following definitions apply:
(1)
‘material’ means a single basic substance or uniformly dispersed mixture of substances;
(2)
‘homogeneous product’ means a product consisting of a single material, having uniform density and composition throughout the product;
(3)
‘non-homogeneous product’ means a product that does not satisfy the requirements of a homogeneous product and that is composed of one or more components, substantial and/or non-substantial;
(4)
‘substantial component’ means a material that constitutes a significant part of a non-homogeneous product; a layer with a mass per unit area ≥ 1,0 kg/m 2 or a thickness ≥ 1,0 mm is considered to be a substantial component;
(5)
‘non-substantial component’ means a material that does not constitute a significant part of a non-homogeneous product; a layer with a mass per unit area < 1,0 kg/m 2 and a thickness < 1,0 mm is considered to be a non-substantial component;
(6)
‘internal non-substantial component’ means a non-substantial component that is covered on both sides by at least one substantial component;
(7)
‘external non-substantial component’ means a non-substantial component that is not covered on one side by a substantial component.
Two or more non-substantial layers that are adjacent to each other, where there are no substantial components in between the layers, shall be considered as one non-substantial component and shall, therefore, be classified in accordance with the criteria for a layer that is a non-substantial component.
