Comparison of flame-retardant protective clothing standards between China, the United States and the European Union
Tag:
Flame retardant test of flame retardant protective clothing GB 5455
(1) In the standard systems of the United States, the European Union and China, the flame retardant testing methods for flame retardant protective clothing in various regions are relatively unified. The United States The vertical combustion method specified in ASTM D 6413 is used in the standard system, the EU uses the surface and bottom burning method specified in IS0 15025, and China uses 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.
