1．Standard -- GB 8624:2006 building products fire testing

GB 8624:2006 Classification for burning behavior of building materials and products

2. Standard Brief-- GB 8624:2006 building products fire testing

GB 8624:2006 This standard replaced GB 8624:1997, this amendment by the European Union standards EN 13501-1:2002.

The standard compared with the GB 86241997 major changes, the main changes are as follows:

- The standard of the paving and pipe insulation materials, combustion provides separately for classification, combustion performance levels by the subscript fl and L to distinguish between, respectively;
- Combustion properties of the material divided by the A-level (homogeneous materials), A-level (composite sandwich materials), B1, B2 and B3 into five levels A1, A2, B, C, D, E, F or AF A_FL1、A_FL2、B_FL、C_FL、D_FL 、E_FL 、F_FL or A_L1、A_L2、B_L、C_L、D_L 、E_L 、F_L

3. GB 8624 the main concern:

Flammability classification：A1、A2、B、C、D、E、F or A_FL1、A_FL2、B_FL、C_FL、D_FL 、E_FL 、F_FL or A_L1、A_L2、B_L、C_L、D_L 、E_L 、F_L

Toxicity：T0、T1、T2

Smoke density：S1、S2、S3

dripping：D0、D1、D2
