Abstract
Specifies requirements for the protection by ventilation of electrical equipment in explosive atmospheres. Section 1 deals with gas or vapour dilution and point extraction ventilation of buildings and rooms; and Section 2 design, construction and testing of ventilation systems required to reduce the temperature of electrical power equipment by heat dissipation.
Scope
This standard sets out requirements for the protection by ventilation of electrical equipment in explosive atmospheres. The standard is in two Sections, as follows:
(a) Section 1-Ventilation of Buildings and Rooms-Gas or Vapour Dilution.
(b) Section 2-Ventilation of Electrical Power Equipment-Heat Dissipation.
Section 1 of this standard relates to the requirements of dilution ventilation and point-extraction ventilation of buildings and rooms.
