《GB/T 7043.2-2001橡胶中铜含量的测定二乙基二硫代氨基甲酸锌光度法》由TC35（全国橡胶与橡胶制品标准化技术委员会）归口，TC35SC2（全国橡胶与橡胶制品标准化技术委员会通用试验方法分会）执行，主管部门为中国石油和化学工业联合会。
本标准规定了以光度法测定橡胶中微量铜含量的方法。本标准适用于铜含量不超过10mg/kg的天然和合成生胶、胶乳、混炼胶及硫化胶。铜含量高于10mg/kg的样品，调整试样质量或适当稀释溶液后也可测定。本方法同样适用于经氢氟酸处理的含二氧化硅的橡胶。

Scope

This standard specifies the photometric method for the determination of trace copper content in rubber. This standard applies to natural and synthetic raw rubber, latex, mixed rubber and vulcanized rubber with a copper content not exceeding 10 mg/kg. For samples with a copper content higher than 10mg/kg, it can also be determined after adjusting the sample quality or diluting the solution appropriately. The method is equally applicable to hydrofluoric acid-treated silica-containing rubbers.
