This standard describes the parameter Measuring method of electrical and electronic products in the salt fog environment, including the sampling analysis and calculation method of salt fog concentration, salt fog sedimentation rate and salt fog sedimentation amount. It is suitable for salt fog exposure measurement in the use environment of electrical and electronic products. The methods cover traditional inhalation method, wet candle method and dry sheet method, as well as online monitoring methods based on Spectrophotometric method, spec-trophotometry, Mie scattering method and resistance method. The standard classifies the impact of salt fog environment parameters on electrical and electronic products, see Appendix B for details.
