6、/IEC62262:2002Nil吕本标准等同采用IEC62262:2002《电器设备外壳对外界机械碰撞的防护等级(UK代码))(英文版)本标准由中国电器工业协会提出。本标准由全国旋转电机标准化技术委员会(SAC/TC26)归口。本标准由上海电器科学研究所(集团)有限公司负责起草，参加起草的单位有:广州电器科学研究院、南阳防爆电气研究所、西安高压电器研究所。本标准主要起草人:陈康、刘功桂、周少中、李中亭、吴庆云、倪佩娟等本标准为首次制定。GB/T20138-2006/IEC62262:2002引言本标准描述了电器

7、设备外壳对外界机械碰撞防护的分级方法。本分级方法适用于多种类型电器设备，但这并不意味着本标准中列出的全部防护等级均适用于某一特定类型的设备。应与设备制造商协商确定设备应具备的防护等级以及表明设备零部件所适用的防护等级。尽可能的在各种场合下采用本分级方法，以促进外壳防护的描述方法和检验各种防护等级试验的统一和一致，并减少检验各种产品所必需的试验器具类型的数量。GB/T20138-2006/IEC62262;2002电器设备外壳对外界机械碰撞的防护等级

8、壳对外界机械碰撞的防护分级。本标准仅适用于对外界机械碰撞防护分级有专门要求的外壳本标准的目的是规定:a)电器设备外壳为保护内部设备因受到机械碰撞而产生有害影响所具备的防护等级的定义;b)防护等级的标志;C)每种标志的要求;d)为确认外壳是否符合本标准的要求而应进行的试验。各技术委员会仍然有权决定在其所制定的标准中采用本分级方法的程度和方式，并对其所辖的设备的“外壳”下定义
