GB/T 2408 Plastics - Determination of flammability - Standard name

GB/T 2408： plastic - Determination of combustion performance - Horizontal method and vertical method

GB/T 2408：Plastics-Determination of burning characteristics-Horizontal and vertical test

GB/T 2408 Plastics - Determination of flammability – Scope of application ：

This standard specifies the test conditions of non-metallic materials in plastic boxes 50W Under flame conditions , Method for laboratory determination of horizontal or vertical combustion performance . This standard specifies the determination of linear combustion rate, residual flame time and combustion length of samples .

GB/T 2408 Plastics - Determination of flammability – Test principle

Fix one end of the rectangular strip sample on the horizontal or vertical fixture , The other end is exposed to the specified test flame , By measuring the linear combustion rate , Evaluate the horizontal combustion behavior of the sample ; By measuring its afterglow and afterglow time 、 Scope of combustion and dripping of combustion particles , Evaluate the vertical combustion behavior of the sample
