《GB/T 14593-2008山羊绒、绵羊毛及其混合纤维定量分析方法 扫描电镜法》由TC513(全国纤维标准化技术委员会)归口,主管部门为国家标准化管理委员会。
本标准代替GB/T14593―1993《山羊绒、绵羊毛及其混合纤维定量分析方法》。本标准规定了使用扫描电子显微镜对山羊绒、绵羊毛及其混合与混纺产品等各类纤维含量进行定量分析的方法。
本标准适用于山羊绒、绵羊毛及其混合纤维与混纺产品。本标准也适用于下列各类纤维及其混纺产品:马海毛、驼绒、兔毛和牦牛绒等。 本标准与GB/T14593―1993相比主要变化如下:
―――增加了“2 规范性引用文件”;
―――修改了有关“鳞片密度、鳞片厚度”定义中相关的英文表达(1993 版的2.4、2.5;本版的3.2、3.3);
―――将原标准的“方法提要”修改为“原理”,并修改了文字叙述(1993版的第3章;本版的第4章);
―――修改了各种状态样品的准备方法,并将用以制取纤维检测样的纤维小段的长度修订为
0.4mm;并且添加了注意事项(1993 版的7.1~7.4 以及7.5;本版的8.1~8.4 以及8.3的注);
―――修改了需要测量细度的纤维根数,由原来的每根必测减少为每组分纤维测量120根(1993版的8.3;本版的9.3);
―――计算结果的表述修改为纤维含量的计算,增加了直径和均方差的计算公式(1993版的第9章;本版的第10章);
―――将固定格式的检测报告删除(1993版的第10章);
―――附录A 内增加了非典型性羊绒外观形态特征的描述及相应的扫描电镜图片(本版的图A.1~图A.8),同时增加了本标准适用范围内的其他特种动物纤维的扫描电镜图片(本版的图A.9~图A.14);
―――附录B内新增了驼绒、马海毛及牦牛绒的纤维密度数据并修改了山羊绒的密度数据(本版的表B.1)。
