IEC 60079-13:2017 gives requirements for the design, construction, assessment, verification and marking of rooms used to protect internal equipment:
\n\u2013 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;
\n\u2013 located in a Zone 2 explosive atmosphere with or without an internal source of gas\/vapour release and protected by artificial ventilation;
\n\u2013 located in a non-hazardous area, containing an internal source of gas\/vapour release and protected by artificial ventilation;
\n\u2013 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.
\nThe 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.
\nThis document also includes requirements related safety devices and controls necessary to ensure that artificial ventilation, purging and pressurization is established and maintained.
\nA 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\u2019s facility, where the final construction such as ducting can be completed on site.
\nThis 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\u00a0 exist to ensure the safety of personnel in this regard.
\nThis second edition cancels and replaces the first edition published in 2010. This edition constitutes a technical revision.
\nThis edition includes the following significant technical changes with respect to the previous edition:
\na) modification of the title of this document to include artificially ventilated room "v" in addition to pressurized room "p";
\nb) addition of types of protection "pb", "pc", and "vc" and removal of types of protection "px", "py", "pz" and "pv";
\nc) definition of the differences between pressurization and artificial ventilation types of protection;
\nd) removal of protection of rooms with an inert gas or a flammable gas from the scope of this document;
\ne) 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.<\/p>\n","protected":false},"excerpt":{"rendered":"
