4 Flame retardant technical specification of decorating materials for multiple unit train 1 Scope This Standard specifies the requirements and test methods for flame retardant performance of decorating materials for multiple unit train. This Standard applies to decorating materials for multiple unit train with an operating speed greater than or equal to 200 km/h. 2 Normative references The following standards contain provisions which, through reference in this Standard, constitute provisions of this Standard. For dated reference, subsequent amendments to (excluding corrections to), or revisions of, any of these publications do not apply. However, the parties to agreements based on this Standard are encouraged to investigate the possibility of applying the most recent editions of the standards. For undated references, the latest edition of the normative document referred to applies.

5 a) Gas sampler: the maximum flow rate of sampling shall be not less than 2 L/min; b) Infrared analyzer: for CO, CO 2 gas analysis, the range for CO: 0.01 % ~ 1 %, for CO 2 : 0.1 % ~ 20 %; c) Gas detection tube: for the detection of HCN harmful gases after combustion; d) Gas collection bag; e) Potentiometric titrator: the accuracy is 0.1 % and above; f) Ion chromatograph Gas analysis Analysis of CO and CO 2 The collected harmful gases are absorbed by the aqueous solution, dried by a drying apparatus with CaCl 2, and then connected to a CO and CO 2 infrared analyzer for gas analysis Preliminary analysis of harmful gases The gas collected in the gas collection bag is preliminarily analyzed by the gas detection tube to determine the type of harmful substances in the gas. This method is for qualitative analysis, not for quantitative analysis (except for HCN) Analysis of HCl, HBr, HF The test method is in accordance with the provisions of GB Analysis of SO 2 gas The gas in the gas collection bag is passed through the gas sampler to absorb it into the formaldehyde buffer absorption solution. The volume of the gas is 2 L. The test method is in accordance with the provisions of GB/T , and the gas concentration is measured Analysis of HCN gas The HCN gas analysis is carried out using the detection tube Analysis of NO x (in NO 1 ) gas The NO x gas analysis is carried out according to the provisions of GB/T Result processing Page 9 of 10
