本标准代替GB/T5989—1998《耐火制品荷重软化温度试验方法(示差升温法)》。本标准规定了使用阿贝型折射仪测定液体化工产品折光率的方法。本标准适用于透明或半透明、折光率范围在1.3000~1.7000的液体化工产品的测定。本标准与原GB/T5989—1998相比,主要技术差异如下:
———对标准名称作了修改;
———按ISO1893:2005重新定义标准的适用范围;
———按ISO1893:2005增加了部分规范性引用文件;
———按ISO1893:2005将部分“注”变成了条文。
Scope
This standard specifies the method for determining the refractive index of liquid chemical products using an Abbe-type refractometer. This standard applies to the determination of transparent or translucent liquid chemical products with a refractive index ranging from 1.3000 to 1.7000.
