《GB/T 15072.14-2008贵金属合金化学分析方法 银合金中铝和镍量的测定 电感耦合等离子体原子发射光谱法》由TC243(全国有色金属标准化技术委员会)归口,TC243SC5(全国有色金属标准化技术委员会贵金属分会)执行,主管部门为中国有色金属工业协会。
本标准规定了银合金中铝和镍量的测定。本部分适用于AgCuNiAl,AgCuNiCe、AgCuNi和AgMgNi合金中铝和镍量的测定。测定范围(质量分数):0.1%~2.5%。 本部分代替GB/T15072.14―1994《贵金属及其合金化学分析方法 银合金中铝量的测定》。
本部分与GB/T15072.14―1994相比,主要有如下变动:
―――名称由《贵金属及其合金化学分析方法 银合金中铝量的测定》变更为《贵金属合金化学分析方法 银合金中铝和镍量的测定 电感耦合等离子体原子发射光谱法》;
―――采用电感耦合等离子体原子发射光谱法代替原标准使用的分光光度法;
―――将方法的适用范围由原标准的AgCuNiAl20�玻勃玻焙辖鹄┱沟剑粒纾茫酰危椋粒臁�AgCuNiCe、AgCuNi和AgMgNi系列合金,其中AgCuNiCe、AgCuNi和AgMgNi为新增系列;
―――铝的测定范围(质量分数)由0.5%~1.2 %扩展到0.1%~2.5%;
―――增加了镍元素的同时测定,测定范围(质量分数)为0.1%~2.5%;
―――采用重复性和相对允许差替代原标准使用的允许差。
Scope
This standard specifies the method for the determination of the amount of aluminum and nickel in silver alloys. This section applies to the determination of the amount of aluminum and nickel in AgCuNiAl, AgCuNiCe, AgCuNi and AgMgNi alloys. Measuring range (mass fraction): 0.1% to 2.5%.
