GB/T 19292.3-2003 in English

《GB/T 19292.3-2003金属和合金的腐蚀 大气腐蚀性 污染物的测量》由TC183（全国钢标准化技术委员会）归口，TC183SC11（全国钢标准化技术委员会金属和合金的腐蚀分会）执行，主管部门为中国钢铁工业协会。
本标准规定了三种用于测量二氧化硫（硫化物）和空气中盐分沉降率的方法。它不包含浓度的测量，二氧化硫和空气中其他污染物浓度的测量应根据标准方法，如：ISO 4221：1980《空气质量 大气环境中二氧化硫质量浓度的确定 钍试剂分光光度法》。

Scope

This standard specifies three methods for measuring the deposition rate of sulfur dioxide (sulfide) and salt in air. It does not contain the measurement of the concentration, the measurement of the concentration of sulfur dioxide and other pollutants in the air should be based on the standard method, such as: IS0 4221: 1980 << air quality Determination of the mass concentration of sulfur dioxide in the atmospheric environment Thorium reagent spectrophotometry. The measurement methods contained in this standard are applied to the characterization of corrosivity at the test site, and the contaminant data obtained by these methods are usually used in the determination of corrosivity classification.
