【Product knowledge】：

Simply put, the flame retardancy of building materials is divided into four categories:
1. Class A, does not burn materials.
2. Class B1, hard to burn materials.
3. Class B2, combustible materials. 4. Class B3, combustible material.
The material that meets the following requirements shall be classified as Class B1 in combustion performance. To
a) Test according to GB/T 8626, and its combustion performance should reach the index specified in GB/T 8626, and no burning droplets are allowed to ignite the filter paper;
b) Test according to GB/T 8625, the average remaining length of each group of specimens is ≥15cm (the remaining length of any specimen is >0cm), and the peak average flue gas temperature of each test is ≤200℃. To
c) Test according to GB/T 8627, and its smoke density grade (SDR) ≤75. To
The standard is mainly to strictly divide the combustion grade of materials. The flame-retardant B1 standard has three main indicators (1) Oxygen index: ≥32.0%; 

(2) Vertical combustion performance: combustion time ≤ 30S, combustion height ≤ 250mm ；
(3) Smoke density grade: ≤75SDR
