Oxygen Index
When a mixture of oxygen and nitrogen at 23+/-2 ℃ is introduced、 the minimum oxygen concentration for material combustion is just maintained、 expressed in volume fraction
The optical density of smoke D
The opacity of smoke is represented by the negative logarithm of relative transmittance
TB/T 3237 Railway Interior Materials - Summary of Fire Testing Standards of the Ministry of Railways
The Chinese Ministry of Railways formulated the "TB/T3237-2010 Technical Conditions for Flame retardancy of Interior Materials for Railway Units" on August 22、 2010、 which was officially implemented on February 1、 2011 and began widespread implementation in July 2013
TB/T 3237-2010 is the first comprehensive flame retardant standard proposed for interior materials of multiple unit trains since their self operation
