Abstract: According to the fire performance test requirements of nonmetallic materials for the high-speed EMU (electric multiple units) second class seat, the differences between current fire standards of TB/T 3237—2010, DIN 5510-2—2009, BS 6853—1999 and EN 45545-2—2013 are compared and analyzed. Then based on EN 45545-2—2013 standard, the seat fire performance is tested and an optimization scheme is proposed, which can meet the highest requirements of EN 45545-2—2013 standard in terms of non-metallic materials or the whole chair flammability. Though the requirements are more comprehensive, there are still deficiencies in EN 45545-2—2013 standard, the fire resistance test for seat nonmetallic materials and the combustion test of the whole seat are not completely corresponding, therefore the standard needs further optimization.
