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.
