轨道车辆用聚氨酯胶黏剂防火测试方法探讨

Discussion on Flammability Test of Polyurethane Adhesive for Railway Vehicles

梳理了欧盟和国内轨道车辆的防火测试标准要求,并根据聚氨酯胶黏剂防火的要求,详细介绍了其主要粘接适用部位,明确了不同应用场合下的检测制样方法、等级要求和同一种产品的替代关系,解决了一直以来由于对测试标准的解读不统一而导致的质量验收过程的困难。

The requirements of flame-retardant test on rail vehicle from European Union and domestic standards were summarized.The application scenes of its main bonding joints were introduced in detail according to the flame-retardant requirements of the polyurethane adhesives.The testing sample preparation methods,grade requirements and the alternative solution of the same product in different application scenes were clarified.The difficulties and risks of the technical&quality acceptance caused by the inconsistent interpretation of the standards were resolved.
