标准摘要
[中文适用范围]： IEC 60079-18:2014 RLV 包含官方 IEC 国际标准及其红线版本。 Redline 版本仅提供英文版本，为您提供了一种快速、简单的方法来比较官方 IEC 标准与其先前版本之间的所有更改。 IEC 60079-18:2014 给出了用于爆炸性气体环境或爆炸性粉尘环境中保护封装类型为“m”的电气设备、电气设备部件和 Ex 组件的构造、测试和标记的具体要求。本部分仅适用于额定电压不超过11 kV的封装电气设备、电气设备封装部件和封装防爆组件（以下始终简称“m”设备）。在可能同时含有爆炸性气体和可燃粉尘的环境中使用电气设备，可能需要额外的保护措施。本标准不适用于不需要大气氧气燃烧的爆炸物粉尘或自燃物质。本标准未考虑因粉尘释放易燃或有毒气体而产生的任何风险。本标准补充和修改了IEC 60079-0的一般要求。当本标准的要求与 IEC 60079-0 的要求相冲突时，以本标准的要求为准。本国际标准与 IEC 60079-0，爆炸性环境 - 第 0 部分：设备一般要求结合使用。第四版取消并取代了 IEC 60079-18:2009 第三版，构成技术修订。请参阅该文件的前言，了解相对于前一版本的技术变更列表。关键词：封装“m”、爆炸性气体环境、爆炸性粉尘环境2018年7月勘误表内容已纳入本次。 [外文原描述]： IEC 60079-18:2014 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60079-18:2014 gives the specific requirements for the construction, testing and marking of electrical equipment, parts of electrical equipment and Ex components with the type of protection encapsulation "m" intended for use in explosive gas atmospheres or explosive dust atmospheres. This part applies only for encapsulated electrical equipment, encapsulated parts of electrical equipment and encapsulated Ex components (hereinafter always referred to as "m" equipment) where the rated voltage does not exceed 11 kV. The application of electrical equipment in atmospheres, which may contain explosive gas as well as combustible dust simultaneously, may require additional protective measures. This standard does not apply to dusts of explosives, which do not require atmospheric oxygen for combustion, or to pyrophoric substances. This standard does not take account of any risk due to an emission of flammable or toxic gas from the dust. This standard supplements and modifies the general requirements of IEC 60079-0. Where a requirement of this standard conflicts with a requirement of IEC 60079-0, the requirement of this standard takes precedence. This International Standard is to be used in conjunction with IEC 60079-0, Explosive atmospheres - Part 0: Equipment-General requirements. This fourth edition cancels and replaces the third edition of IEC 60079-18:2009, and constitutes a technical revision. Please refer to the foreword of the document for a listing of the technical changes with respect to the previous edition. Keywords: encapsulation "m", explosive gas atmospheres, explosive dust atmospheres The contents of the corrigendum of July 2018 have been included in this copy.
