Plugs and socket-outlets for household and similar purposes — Part 1: General requirements 1 Scope This document specifies the technical requirements for the marking, protection against electric shock, structure, electrical performance and mechanical performance of plugs and socket-outlets for household and similar purposes. This document applies to plugs and fixed or portable socket-outlets for A.C. only, with or without earthing contact, with a rated voltage greater than 50 V but not exceeding 440 V and a rated current not exceeding 32 A, intended for household and similar purposes, either indoors or outdoors. The rated current is limited to 16A maximum for fixed socket-outlets provided with screwless terminals. This standard does not cover requirements for flush mounting boxes: however, it covers only those requirements for surface-type mounting boxes which are necessary for the tests on the socket-outlet. Note 1: General requirements for mounting boxes are given in GB/T 17466. This standard also applies to plugs which are a part of cord sets, to plugs and portable socket-outlets which are a part of cord extension sets and to plugs and socket-outlets which are a component of an appliance, unless otherwise stated in the standard for the relevant appliance. This document is not applicable to: ——plugs, socket-outlets and couplers for industrial purposes; ——appliance couplers; ——plugs, fixed and portable socket-outlets for ELV; Note 2: ELV values are specified in GB/T 16895.21. ——fixed socket-outlets combined with fuses, automatic switches, etc. Note 3: Socket-outlets with pilot lights are allowed provided that pilot lights comply with the relevant standard, if any. Plugs and socket-outlets complying with this standard shall be suitable for use at ambient temperatures not normally exceeding +40°C, but their average over a period of 24h does not exceed +35°C, with a lower limit of the ambient air temperature of –5°C. Socket-outlets complying with this standard are only suitable for incorporation or mounting in equipment in such a way and in such a place that it is unlikely that the surrounding temperature exceeds 35°C. In locations where special conditions prevail, such as in ships, vehicles and the like and in hazardous locations, for example where explosions are liable to occur, special constructions may be required. 2 Normative reference The following documents contain provisions which, through reference in this text, constitute provisions of this document.

如有IP代码，应标在当插座按正常使用安装和接线时清晰可辨的位置。 按7.2.5b)分类的插座，应用一个三角形来标识，并应在插座安装好后明显可见。如果这类插座具有一个区别于正常电路所用的交界面结构的除外。 8.4 对插头和移动式插座，8.1中规定的标志(型号除外)应在电器附件接线和安装时清晰易辨。 Ⅱ类设备用的插头和移动式插座，不得标出Ⅱ类结构的符号。 注：可拆线的电器附件的型号可以标在外壳和盖的里面。 8.5 中性线(极)专用端子应标出字母N。 连接保护导线的接地端子应标出符号 。 上述标志不得位于螺钉或其他易拆卸的部件上。 注：“易拆卸的部件”是指在正常安装插座和组装插头时可以拆卸的那些部件。 不可拆线电器附件中的端头不必标志。 2P+ 的插头插座应遵循面对插座接地线(极)在上方、左边是中性线(N极)、右边是相线(L极)的标注规定。 用以连接不构成插座主要功能的导线的端子应有明显的特征，其用途不言自明或已在固定到电器附件的布线图中注明者除外。 电器附件端子可通过如下办法来识别： ——用GB/T 5465.2的图形符号或颜色和/或字母一数字系统构成的标志； ——本身的物理尺寸或相对位置。 霓虹灯或指示灯的引线不视作本条所述的导线。 8.6对与插座成一个整体的明装式安装盒，如IP代码高于IP4X，或高于IPX2，其IP代码应标在与其相对应外壳的外面，并使插座按正常使用安装和接线之后清晰易辨。 8.7声明带有IP代码高于IPX0防护等级的固定式暗装式或半暗装式插座，应通过其标志或制造商产品目录或使用说明书，给出其位置和特殊措施(例如：安装盒、安装面的类型、插头等)，确保获得规定的防护等级。 是否合格，通过观察检查。 8.8 在无任何附加放大的情况下，以正常或矫正视力进行观察，标志应经久耐用，清晰易辨。 是否合格，通过观察并进行如下试验检查： 用一块浸透蒸馏水的医用脱脂棉在约15 s内擦拭15个来回；随后用一块浸透汽油的医用脱脂棉在约15 s内擦拭15个来回。 试验期间，应采用约2 N/cm2的压力将脱脂棉压在标志上。 注1：用压印、铸、压、刻等办法制成的标志不进行此项试验。 注2：所用汽油宜为95％正己烷(化学文摘服务注册号码，CAS RN，110-54-3)。 9尺寸检查 9.1 电器附件和明装式安装盒应符合相应的标准和插头插座系统量规(如有)的要求。 符合相应的标准的插头，应保证能插入相应的固定式或移动式插座。 单相插头插座应符合GB/T 1002的要求。 三相插头插座应符合GB/T 1003的要求。 是否合格，通过下列来检查。 首先，插座要用符合相应标准要求的、具有最大尺寸的插销的插头插入10次和拔出10次。插销的尺寸通过测量或用量规来检查。 除非另有规定，量规的制造公差应如表2所示要求。量规的设计应采用本文件中最不利的尺寸。 表2量规公差 检查下列项目用量规 量规公差 mm 插销直径或厚度 0 -0.02 与插销直径和与接触表面之间的距离相应的插孔的尺寸 +0.02 0 插销宽度 0 -0.05 插销长度 0 -0.1 插销间距 或 (视情况而定) 从插合面到插套初触点的距离(插座用) 0-0.05或+0.050(视情况而定) 导入零件 ±0.03 注1：在某些场合(例如：中心之间的距离)，可能需要检查两者最极端的尺寸。 注2：量规见GB/T 1002、GB/T 1003。 9.2在某一给定的系统内，插头应不能与下列插座插合： ——电压额定值较高的或电流额定值较低的插座； ——带电极数不同的插座1)；专门制造允许与极数较少的插头插合的插座除外，但不得有任何危险，例如带电极与接地触头之间的连接或接地电路断路等。 我国现有插头插座系统的插头如是I类设备用的插头，应不可能插入专为插合Ⅱ类设备的插头而设计的插座。 是否合格，通过观察或用量规来进行手动试验检查。量规制造公差应符合表2的规定。 在有怀疑情况下，不可插入性检查通过应用合适的量规，施力1 min来检查。对于额定电流不超过16 A的电器附件施加150 N的力，对于其他的电器附件施加250 N的力。 1)此条在我国仅适用于转换器插座。 如所用的弹性材料和热塑性材料会影响试验结果，此项试验应在(40±2)℃2)的环境温度下进行，电器附件和量规均应处于此温度。 对硬质材料，如热固性树脂、陶瓷材料等，只要符合相关的标准就保证能符合此项要求。 |
