Test basis:
GB 8624-2012 Classification of combustion performance of building materials and products. The specific test methods for the combustion performance grades and classification criteria of flat building materials and products in Table 2 of Clause 5.1.1 are as follows:
1. GB/T 14402-2007 Combustion performance of building materials and products - Determination of calorific value;
2. GB/T 20284-2006 Single-unit combustion test for building materials or products.
GB/T 20284 Installation and fixing:
The sample was sprayed on the substrate (the substrate was calcium silicate board with a density of 900kg//m^(3)900 \mathrm{~kg} / \mathrm{m}^{3} ), and the surface density of the topcoat spraying was 0.25kg//m^(2)0.25 \mathrm{~kg} / \mathrm{m}^{2} .
/_\T\triangle \mathrm{T} - Temperature rise [^(@)C];Deltam\left[{ }^{\circ} \mathrm{C}\right] ; \Delta \mathrm{m} - Mass loss [%];t_(f)-[\%] ; \mathrm{t}_{\mathrm{f}}- Burning time [s][\mathrm{s}]
PCS - total calorific value of combustion [MJ/kg or MJ//m^(2)\mathrm{MJ} / \mathrm{m}^{2} ]; FIGRA - Burning growth rate index for classification [W/s]
For levels A2 and B, FIGRA = FIGRA _(0.2MJ){ }_{0.2 \mathrm{MJ}}
For levels C and D, FIGRA = FIGRA O_(0.4MJ)\mathrm{O}_{0.4 \mathrm{MJ}} LFS - Flame lateral extension [m]
THR600s - total heat release at 600 seconds [MJ] SMOGRA - Smoke Generation Rate [m^(2)//s^(2)]\left[\mathrm{m}^{2} / \mathrm{s}^{2}\right]
TSP 600 s - Total smoke production at a time of 600 seconds [m^(2)]\left[\mathrm{m}^{2}\right]

Combustion performance level:
According to GB 8624-2012, the combustion performance grades of building materials and products are based on the combustion performance grades and classification criteria of flat building materials and products in Table 2 in Clause 5.1.1. in conclusion:
According to the test results and combustion performance grade criteria, the combustion performance mark is: GB 8624 A (A2-s1, d0);
The sample complies with Class A of GB 8624-2012 Combustion performance grades and classification criteria for flat building materials and products.
