浅析GB/T601–2002氧化锌摩尔质量的溯源性

Brief Analysis on Traceability for Mole Mass of Zinc Oxide Used by GBT 601–2002

分析GB/T 601–2002中EDTA标准滴定溶液标定中工作基准试剂氧化锌摩尔质量取值的有效数字和计算所采用的相对原子质量,结合IUPAC对锌相对原子质量的修订情况,强调在标准中应标明所引用相对原子质量的来源,以增强其溯源性。

It was commented on significant figures of mole mass of Zinc Oxide and relative atomic weight in calibrating for EDTA standard volumetric solution in GB/T 601-2002. It was noted source of used standard atomic weight to get traceability using revise of Zinc in IUPAC reports for a reference.
