철도차량 시트재료의 개별 및 조립체 시험에 대한 독성 비교

초록

The advanced country established the test standard (e.g., BS, EN) to measure the toxic gases quantitatively and, have applied to enhance the fire safety of railway car. We must also follow the procedures to use interior material for railway car as stated the Safety regulation for the urban railway car. Currently, various interior materials are used to obtain the fire safety of railway car. The amount of toxic gases moved into colorimetric gas detector tubes from the ISO 5659 chamber was measured and compared the results for composite and single materials. As result of gas analyses, The smoke density(Ds) of combustion gases producted from composite of seat material had the excellent value than single material
