摘　　要：由于现行的汽车用制动器衬片标准GB 5763—2018《汽车用制动器衬片》规定:衬片中不得含有石棉。基于此,采用GB/T 23263—2009《制品中石棉含量测定方法》的方法考察了采用无机和有机两种前处理方式对汽车用制动器衬片中石棉定性定量检测的影响。结果表明:有机制样和无机制样处理方式对刹车衬片摩擦材料样品中石棉测试无明显影响,两种制样方式均可行。As the current automotive brake lining standard GB 5763—2018 Brake Linings for Automotive stipulates that asbestos shall not be contained in the lining.Based on this,the influence of inorganic and organic pretreatment methods on the qualitative and quantitative detection of asbestos in automotive brake linings was investigated by using the method of GB/T 23263—2009 Determination of Asbestos in Products.The results show that the organic and inorganic sample preparation methods have no obvious effect on the test of asbestos in brake lining friction material samples,and the two sample preparation methods are feasible.
