在ＩＳＯ９２２３金属和合金─大气腐蚀性分类标准的基础上，针对我国大气环境的具体情况，提出了适合我国大气环境腐蚀性分类的技术指标，并对我国典型地区的大气环境的腐蚀性进行了分类，得到了既符合ＩＳＯ分类原则又更适合我国实际情况的结果。
Based on the classification standard of ISO9223 Metals and Alloys-Atmospheric Corrosion, according to the specific conditions of atmospheric environment in our country, we put forward the technical indexes suitable for the corrosivity classification of atmospheric environment in our country, and classified the corrosivity of atmospheric environment in typical areas of our country , We got the result which is both accordant with the principle of ISO classification and more suitable for the actual situation in our country.
