According to the testing standards of GB8624-1997 “Method for Grading Combustion Performance of Building Materials”, the flame retardant testing standards for fire-retardant fabrics for building materials are divided into level A (non-combustible materials), level B1 (flame-retardant materials), and level B2 ( Combustible materials), Class B3 (flammable materials).
The content of the B1 flame retardant test is:
Tested according to GB/T8626, its combustion performance should reach the indicators specified in GB/T8626, and no burning drippings are allowed. The phenomenon of igniting filter paper;
Tested in accordance with GB/T8625, the average remaining length of each group of test pieces is ≥15CM (the remaining length of any test piece is >0CM), and the average smoke in each test Peak air temperature ≤200℃;
Tested according to GB/T8627, its smoke density level (SDR) ≤75.
