《GB/T 19198-2008贵金属及其合金对铂、对铜热电动势的测量方法》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。
本标准规定了贵金属及其合金材料在0℃~300℃温度范围内对铂热电动势的测量方法,规定了贵金属及其合金材料在0℃~200℃温度范围内对铜热电动势的测量方法。
本标准适用于贵金属及其合金材料在0℃~300℃温度范围内对铂热电动势的测量;适用于贵金属及其合金材料在0℃~200℃温度范围内对铜热电动势的测量。其他类型的金属及其合金材料对铂或对铜热电动势的测量亦可参照进行。 本标准代替GB/T19198―2003《贵金属及其合金对铂热电动势的测试方法》。
本标准与GB/T19198―2003相比,主要有如下变动:
―――将标准名称修改为“贵金属及其合金对铂、对铜热电动势的测量方法”;
―――增加了贵金属及其合金材料在0℃~200℃温度范围内对铜热电动势的测量;
―――增加了比较电极铜丝的纯度、尺寸;
―――增加了比较电极铜丝的清洗、退火处理方式;
―――与原标准相比在文字以及示意图方面进行了编辑性修改。
Scope
This standard specifies the measurement method for platinum thermal electromotive force of precious metals and their alloy materials in the temperature range of 0 °C to 300 °C, and specifies the measurement method of copper thermal electromotive force of precious metals and their alloy materials in the temperature range of 0 °C to 200 °C. This standard is applicable to the measurement of the thermal electromotive force of platinum in the temperature range of 0 ° C to 300 ° C by precious metals and their alloy materials; it is suitable for the measurement of the thermal electromotive force of copper by precious metals and their alloy materials in the temperature range of 0 ° C to 200 ° C. Other types of metals and their alloy materials can also refer to the measurement of platinum or copper thermal electromotive force.
