摘　　要：电器产品爬电距离的限值与器具微观环境的材料组和污染等级密切相关,商用电器因其相对"恶劣"的使用环境,微观环境污染等级的判定较为复杂。该文对比总结18个不同商用电器标准中微观环境污染等级的规定,研究微观环境污染等级的判定方法,分析微观环境污染等级的判定案例,以期对商用电器检测同行有所启发。The limit of creepage distance of electrical products is closely related to the material group and pollution degree of the microenvironment of the appliance. Due to the relatively "bad" use environment of commercial electrical appliances, the judgment of the their microenvironment pollution degree is more complicated. This paper compares and summarizes the regulations of microenvironment pollution degrees in 18 different commercial electrical appliances standards, studies the judgment methods of microenvironment pollution degrees,and analyzes the judgment cases of microenvironment pol ution degrees, so as to inspire commercial electrical appliance testing peers.
