Flammability of Interior Materials for Buses

1 Scope

GB 38262-2019 is the Chinese national standard on flammability of interior materials for buses, in the field of environment and health protection, safety. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 14 October 2019 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 July 2020. Classification: ICS 13.220.40, CCS T09. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This Standard stipulates the terms and definitions, technical requirements, test methods and the requirements of implementation date of flammability of interior materials for buses. This Standard is applicable to the assessment of flammability of interior materials for Type-M2 and Type-M3 buses. This Standard does not include electrical devices (various electric appliance modules, such as air conditioning assembly control switch, wiring harness, electric appliance control panel, navigator, radio, DVD module and driving combination meter), lamps, airbags (curtains), bathroom accessories (such as toilet, washbasin and water tank) and laminboard whose external layer is metallic material and internal layer is non- metallic material.
