GB 25286.2-2010 Non-electrical equipment for explosive atmospheres—Part 2:Protection by flow restricting enclosure"fr"

Scope

This part specifies the structure and test requirements of the current-limiting enclosure type "fr" for non-electrical equipment used in explosive environments. However, only in rare cases will the environment outside the enclosure become explosive and last for a very short time.
This part is a supplement to the requirements of GB25286.1, and the provisions of GB25286.1 apply to all current-limiting enclosure type equipment.
Equipment that meets the requirements of this part can meet the requirements of Class II, Gc-level and Class III, Dc-level equipment. The anti-ignition type specified in this part is not suitable for use with equipment of non-Gc and Dc-level protection types.
