Scope

This Part of GB 3836 specifies the requirements for the design, construction,
testing and marking of electrical apparatus with type of protection increased
safety "e" intended for use in explosive gas atmospheres. This Part applies to
electrical apparatus where the rated voltage does not exceed 11 kV r.m.s. a.c.
or d.c. Additional measures are applied to ensure that the apparatus does not
produce arcs, sparks, or excessive temperatures in normal operation or under
specified abnormal conditions.
This Part supplements and modifies the general requirements of GB 3836.1-
2010. Where a requirement of this Part conflicts with a requirement of GB
3836.1-2010, the requirement of this Part takes precedence.
