GB/T 519-2008 in English

《GB/T 519-2008充气轮胎物理性能试验方法》由TC19（全国轮胎轮辋标准化技术委员会）归口，主管部门为中国石油和化学工业联合会。
本标准规定了充气轮胎（外胎、内胎和垫带）物理性能试验方法用术语和定义、试样制备、外胎物理性能试验、轮胎内衬层渗透分析测定方法、内胎物理性能试验、垫带物理性能试验。本标准适用于轿车轮胎、载重汽车轮胎、农业轮胎、工程机械轮胎和工业车辆充气轮胎。本标准不适用于航空轮胎、摩托车轮胎和力车轮胎。 本标准代替GB/T 519-2003《充气轮胎物理性能试验方法》。
本标准与GB/T 519-2003的主要差异如下：
――增加了子午线轮胎外胎特有部位胶料类型的相关试验内容；
――增加了“建议优先选用以切削方式（采用切片机）直接制备标准厚度试样”；
――增加了全钢子午线轮胎胎圈部位胎体钢帘线密度的测定；
――增加了纤维子午线轮胎纤维冠带层帘线的相关取样及试验内容；
――增加了子午线轮胎胎体层、带束层、钢帘线的取样及试验相关内容；
――增加了子午线轮胎内衬气密胶层渗透性的分析观测试验内容。
