腐蚀性空气环境的分级及检测方法

介绍了国外有关腐蚀性空气环境的分级标准及其检测方法。环境中的腐蚀性气体可对电子元器件及自动控制设备产生腐蚀，影响其性能。根据腐蚀性的严重程度，美国仪器学会标准中将腐蚀性空气环境分为四级。环境腐蚀性置于腐蚀性环境中的铜试条进行检测。

Classification and Detection of Corrosive Atmospheric Environment

The classification standards and detection methods for corrosive atmospheric environment used abroad are introduced in the paper. The corrosive gas in the ambient air may corrode electronic components and automatic control equipments,affecting their performance. Corrosive atmospheric environment is classified into four grades by Instrument Society of America according to its corrosivity. The corrosivity can be detected by using a specially prepared copper coupon laid in the atmospheric environment.
