IEC 60079-13:20 17给出了用于保护内部设备的房间的设计、建造、评估、验证和标记的要求: -位于1区或2区或21区或22区爆炸性环境中，没有气体/蒸气释放的内部源，并通过加压保护； -位于2区爆炸性环境中，有或没有内部气体/蒸汽释放源，并受到人工通风的保护； -位于非危险区域，包含气体/蒸汽释放的内部源，并受到人工通风的保护； -位于1区或2区或21区或22区爆炸性环境中，含有气体/蒸气释放的内部源，并受到加压和人工通风的保护。 本文中使用的术语“房间”包括单个房间、多个房间、完整的建筑物或包含在建筑物内的房间。房间旨在方便人员进入，包括入口和出口管道。设计成允许人员进入的隔音罩和其他类似的外壳可以被认为是房间。 本文件还包括与确保建立和维护人工通风、吹扫和加压所需的安全装置和控制相关的要求。 现场组装或建造的房间，可以在陆地上，也可以在海上。该房间主要用于最终用户安装，但也可以在制造商的设施中建造和评估，最终的建造（例如管道）可以在现场完成。 本文件没有规定为确保人员在室内毒性和温度方面有足够的空气质量所需的方法。国家或其他法规和要求可能？存在以确保这方面人员的安全。 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: a)修改本文件的标题，除加压房间“p”外，还包括人工通风房间“v”； b)添加保护类型“pb”、“pc”和“vc”并移除保护类型“px”、“py”、“pz”和“pv”； c)加压和人工通风保护类型之间差异的定义； d)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； e)增加信息性附件，以包括可以使用和关联保护加压或人工通气或加压和人工通气类型的应用示例教育指南。

IEC 60079-13:2017 gives requirements for the design, construction, assessment, verification and marking of rooms used to protect internal equipment:
– located in a Zone 1 or Zone 2 or Zone 21 or Zone 22 explosive atmosphere without an internal source of gas/vapour release and protected by pressurization;
– located in a Zone 2 explosive atmosphere with or without an internal source of gas/vapour release and protected by artificial ventilation;
– located in a non-hazardous area, containing an internal source of gas/vapour release and protected by artificial ventilation;
– located in a Zone 1 or Zone 2 or Zone 21 or Zone 22 explosive atmosphere containing an internal source of gas/vapour release and protected by both pressurization and artificial ventilation.
The term "room" used in this document includes single rooms, multiple rooms, a complete building or a room contained within a building. A room is intended to facilitate the entry of personnel and includes inlet and outlet ducts. An acoustic hood and other like enclosures designed to permit the entry of personnel can be considered as a room.
This document also includes requirements related safety devices and controls necessary to ensure that artificial ventilation, purging and pressurization is established and maintained.
A room assembled or constructed on site, can be either on land or off-shore. The room is primarily intended for installation by an end-user but could be constructed and assessed at a manufacturer’s facility, where the final construction such as ducting can be completed on site.
This document does not specify the methods that may be required to ensure adequate air quality for personnel with regard to toxicity and temperature within the room. National or other regulations and requirements may？ exist to ensure the safety of personnel in this regard.
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:
a) modification of the title of this document to include artificially ventilated room "v" in addition to pressurized room "p";
b) addition of types of protection "pb", "pc", and "vc" and removal of types of protection "px", "py", "pz" and "pv";
c) definition of the differences between pressurization and artificial ventilation types of protection;
d) removal of protection of rooms with an inert gas or a flammable gas from the scope of this document;
e) 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.
