IEC 60079-13:20 17（E）给出了用于通过加压或人工通风或两者保护内部设备的房间的设计、建造、评估、验证和标记要求，当位于爆炸性气体环境或可燃粉尘环境危险区域时，有或没有可燃气体或蒸汽的内部源。它还包括位于非危险区域的房间，该房间具有易燃气体或蒸汽的内部释放源。本文件涉及部分在制造商设施中建造并打算在现场完成最终安装的房间，以及完全在现场建造的房间。部分建造在制造商设施中的房间可能包括第三方验证。对于现场建造的房间，工厂操作员可以使用本文件作为评估这些设施的指南。本文件是对加压房间“p”和人工通风房间“v”设备保护要求的重大技术修订，应视为引入了所有新要求。第二版取消并取代了2010年出版的第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更: -修改本文件标题，除加压房间“p”外，还包括人工通风房间“v” -添加保护类型“pb”、“pc”和“vc”，并删除保护类型“px”、“py”、“pz”和“pv” -加压和人工通风保护类型之间的区别的定义； -将具有惰性气体或易燃气体的房间的保护从本文件的范围中移除； -增加一个信息性附件，以包括可使用保护性加压或人工通气或加压和人工通气类型的应用实例和相关指南。有关本文件范围的其他信息可在第1条中找到。

IEC 60079-13:2017(E) gives requirements for the design, construction, assessment, verification and marking of rooms used to protect internal equipment by pressurization or artificial ventilation or both as applicable when located in an explosive gas atmosphere or combustible dust atmosphere hazardous area with or without an internal source of a flammable gas or vapour. It also includes a room located in a non-hazardous area that has an internal source of release of a flammable gas or vapour. This document deals with rooms that are partially constructed in a manufacturer’s facility and intended to have the final installation completed on-site, as well as rooms that are constructed completely on-site. Rooms partially constructed in a manufacturer’s facility may include third-party verification. For rooms built on-site, this document can be used by plant operators as a guide for assessment of those facilities. This document represents a major technical revision of the requirements for equipment protection by pressurized room "p"and artificially ventilated room "v"and should be considered as introducing all new requirements. This second edition cancels and replaces the first edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- modification of the title of this document to include artificially ventilated room "v"in addition to pressurized room "p"
- addition of types of protection "pb", "pc", and "vc"and removal of types of protection "px", "py", "pz"and "pv"
- definition of the differences between pressurization and artificial ventilation types of protection;
- removal of protection of rooms with an inert gas or a flammable gas from the scope of this document;
- addition of an informative annex to include examples of applications where types of protection pressurization or artificial ventilation or pressurization and artificial ventilation can be used and associated guidelines. Additional information regarding the scope of this document can be found in Clause 1.
