本标准自实施之日起,代替GB/T12622—1990。本标准规定了管法兰用垫片应力松弛的A、B两种试验方法。本标准是对GB/T12622—1990《管法兰垫片 压缩率及回弹率试验方法》的修订,与GB/T12622—1990相比主要变化如下:
———对标准的适用范围作了修改,增加了非石棉橡胶垫片,聚四氟乙烯垫片,膨胀或改性聚四氟乙烯垫片,柔性石墨复合垫片,具有非金属覆盖层的齿形金属、波形金属和波齿形金属垫片等;
———试验方法A 中,针对所增加的垫片种类,补充增加了相应的压头直径、试样预处理方法和试验载荷等规定;
———试验方法B中,补充增加了垫片总载荷的规定;
———试验温度改为21℃~30℃,以便与ASTM F3699一致;
———增加了对试验次数和试验报告内容的规定。
