本标准于1996年首次发布,本次为第一次修订。本标准代替GB/T16258―1996《棉纤维含糖试验方法 定量法》。本标准规定了用3,5-二羟基甲苯-硫酸溶液作显色剂,使用分光光度计定量测定棉花所含总糖的测定方法。本标准适用于原棉、棉条、棉卷等。 本标准与GB/T16258―1996相比,主要变化如下:
a) 增加了警示内容;
b) 修改了第1章“范围”的内容;
c) 修改了规范性引用文件,并增加了引用标准;
d) 增加了真空抽滤设备和烘箱;
e) 对第7章“样品的制备”增加了棉样的贮存说明,并对内容进行了修改;
f) 增加了回潮率的测试,按公定回潮率折算含糖率作为试验结果;
g) 调整与修改了第8章“试验步骤”的内容;
h) 修改了计算公式;
i) 删除了回收率;
j) 删除了附录A。
