标准摘要
[中文适用范围]： 本国际标准规定了用于ISO 9223中大气腐蚀性分类的腐蚀性估算所需参数的测量方法。本国际标准规定了用于以下目的的参数的测量方法：基于标准金属第一年腐蚀率计算的规范性腐蚀性估算；以及基于暴露环境表征的参考性腐蚀性估算。本国际标准未描述所测参数的常规分析技术，因为这取决于实验室可用的分析技术。二氧化硫（SO2）和氯离子（Cl-）沉积率的特定测量方法以及不同测量方法的转换因子在附录A、B、C、D、E和F中给出。有关表征大气暴露场所一般情况的方法，参见ISO 8565。 [外文原描述]： ISO 9225:2012 specifies methods for measuring the parameters needed for corrosivity estimation used for classification of the corrosivity of atmospheres in ISO 9223. ISO 9225:2012 specifies methods for the measurement of environmental parameters for normative corrosivity estimation based on calculated first-year corrosion rates of standard metals, and informative corrosivity estimation based on characterization of the exposure environment. It does not describe the usual analytical techniques for the measured parameters since this depends on the available analytical techniques used in laboratories. Specific methods for deposition measurement of SO 2 and Cl - deposition rates and conversional factors for comparison of different measuring methods are given.
