二氧化硫潮湿大气试验ISO和DIN方法对比

Comparison of Sulfur Dioxide Test in A Humid Atmosphere From ISO and DIN Methods

二氧化硫是现代城市和工业区大气主要污染物。二氧化硫潮湿大气试验通过实验室模拟真实环境条件的二氧化硫、温度、湿度、升降温、通风、凝露等参数和过程影响,用于评价系统的防腐蚀性能。本文对ISO和DIN二氧化硫潮湿大气试验标准内容进行分析比较,探讨标准间区别联系,提出试验注意点。

Sulfur dioxide is a major pollutant in the atmosphere of modern cities and industrial areas.The sulfur dioxide humid atmosphere test simulates the parameters and process effects of sulfur dioxide,temperature,humidity,temperature rise and fall,ventilation,condensation,etc.under real environmental conditions in the laboratory,to evaluate the corrosion resistance performance of the system.From the sulfur dioxide tests in humid atmospheres of ISo and DIN,this paper discusses the differences and relations between the standards,and puts forward the key points for the use of the standards by analyzing and comparing.
