Flame retardant standard fabric flame retardant clothing flame retardant test

(1) In the standard systems of the United States, the European Union and China, the flame retardant testing methods for protective clothing in various regions are relatively unified. The American standard system Zhongdu adopts the vertical burning method specified in ASTM D 6413, the EU adopts the surface and bottom burning method specified in IS0 15025, and China adopts the vertical burning method specified in GB 5455.

(2) In addition to flame retardant testing of simple fabrics, the American standard system also formulates testing methods for heat transfer performance, burning dummies, etc. The system is relatively It is complete and the simulation of the combustion environment is also relatively realistic.

(3) The EU standard system has a comprehensive range of flame retardant testing. In addition to direct contact flame testing methods, it also includes thermal conductivity, radiation protection and other properties. Testing and Requirements.

(4) Although China has formulated many standards, they mainly focus on evaluating the flame retardant performance of protective clothing through testing the flame retardant properties of fabric samples. There is still a big gap compared with the US and EU standard systems.
