《GB/T 17362-2008黄金制品的扫描电镜X射线能谱分析方法》由TC38(全国微束分析标准化技术委员会)归口,主管部门为国家标准化管理委员会。
本标准代替GB/T 17362-1998《黄金饰品的扫描电镜X 射线能谱分析方法》和GB/T 17723-1999《黄金制品镀层成分的X 射线能谱测量方法》两个标准。
本标准规定了用配置在扫描电镜上的X射线能谱仪对黄金制品化学成分进行无损定量分析的方法和技术要求。
本标准与GB/T 17362-1998和GB/T 17723-1999两个标准相比主要修改如下:
―――将适用范围进行了合并,使其能分别适用于不同含金量的K 金制成的黄金制品和表面有含金镀层的镀金制品的镀层成分的测定这两种情况;
―――将原来两个标准的相关章节,删去重复的部分,对不同的部分进行整理加工形成新的文本;
―――删去了GB/T 17723中“术语”这一节;
―――原标准中“饰品”一律改为“制品”;
―――本标准不再规定选用的校正程序,操作人员可根据实际分析的试样,自行选择采用;
―――着重强调测定镀层制品时,工作电压的选择,这是对镀层成分能否测准的关键所在。
Scope
This standard specifies the test method for qualitative and quantitative analysis of gold elements in gold products using X-ray energy spectrometer. It is applicable to various pure gold, K-gold and gold-plated jewelry as well as gold jewelry with gold-plated surface.
