本标准于1987年6月首次发布。本标准代替GB/T7814—1987《异丙醇》。本标准规定了工业用异丙醇的要求、试验方法、检验规则以及标志、包装、运输和贮存等。本标准适用于工业用异丙醇的生产、检验和销售。本标准与GB/T7814—1987相比主要变化如下:
———技术要求中取消产品等级划分,只设一个等级(1987年版的第1章,本版的3.2);
———取消了沸程项目(1987年版的第1章,本版的3.2);
———指标与GB/T7814—1987优级品比较,色度(铂钴色号)由≤5修改为≤10;水分由≤0.15%修改为≤0.20%;硫化物质量分数由≤1mg/kg修改为≤2mg/kg(1987年版的第1章,本版的3.2);
———密度试验方法增加数字密度计法(U 型振动管法),作为仲裁法(1987年版的2.2,本版的4.6);
———水分试验方法由气相色谱法改为卡尔·费休法—容量法(仲裁法)和卡尔·费休法—库仑电量法(1987年版的2.6,本版的4.8);
———异丙醇含量的试验方法由填充柱气相色谱法修改为毛细管柱气相色谱法(1987年版的2.4,本版的4.4);
———增加了检验分类,规定了出厂检验项目(见5.1);
———增加了资料性附录A、附录B(见附录A、附录B)。
