CMVSS TSD No. 302与49 CFR 571.302测试方法是否一样
2022-06-11 08:34:00 【中科易朔】
CMVSS TSD No. 302与49 CFR 571.302(即FMV SS302)的测试方法实际上是一样的。
只是CMVSS TSD No. 302是加拿大标准,49 CFR 571.302(也就是FMV SS302)是美国标准,都是针对汽车内饰材料,也就是针对汽车用的非金属材料的阻燃防火标准。
CMVSS TSD No. 302、49 CFR 571.302(FMV SS302)测试方法和原理及要求完全一致。
该标准只是水平燃烧测试,属于简单的易燃性测试,难度系数较低。
CMVSS TSD No. 302与49 CFR 571.302的测试原理
将试样水平地夹持在U形支架上,在燃烧箱中用规定高度火焰点燃试样的自由端15s后,确定试样上火焰是否熄灭,或何时熄灭,以及试样燃烧的距离和燃烧该距离所用时间。
CMVSS TSD No. 302与49 CFR 571.302的指标要求
FMVSS/CMVSS 302:燃烧速率≤102mm/min,或者燃烧时间≤60s且燃烧长度≤51mm。
