本标准于1981年首次发布。
本标准是对GB 2440-1991《尿素》和GB/T 13257-1991《工业用尿素灰分的测定 重量法》的修订。
本标准规定了尿素的技术要求试验方法检验规则以及标识包装运输和贮存。
本标准适用于由氨和二氧化碳合成制得的尿素,分为工业用和农业用二类。其主要用途为在农业上用作肥料,在工业上用作塑料、树脂、涂料、医药等工业用的原料。
本标准与GB 2440-1991的主要技术差异如下:
1、在技术要求中调整了总氮含量指标、水分指标和粒度指标,增加了大颗粒尿素粒度指标,粒度项粒径范围分为四档。
2、将GB/T 13257-1991《工业用尿素灰分的测定 重量法》作为本标准附录A,供型式检验用。
3、在检验规则中对采样方法作了修改。
本标准自实施之日起,同时代替GB 2440-1991和GB/T 13257-1991。
