标准简介：This part of IEC 60079 specifies the construction and testing of intrinsically safe apparatus
intended for use in an explosive gas atmosphere and for associated apparatus, which is
intended for connection to intrinsically safe circuits which enter such atmospheres.
This type of protection is applicable to electrical apparatus in which the electrical circuits
themselves are incapable of causing an explosion in the surrounding explosive atmospheres.
This standard is also applicable to electrical apparatus or parts of electrical apparatus located
outside the explosive gas atmosphere or protected by another type of protection listed in
IEC 60079-0, where the intrinsic safety of the electrical circuits in the explosive gas
atmosphere may depend upon the design and construction of such electrical apparatus or parts
of such electrical apparatus. The electrical circuits exposed to the explosive gas atmosphere
are evaluated for use in such an atmosphere by applying this standard.
The requirements for intrinsically safe systems are provided in IEC 60079-25. The
requirements for intrinsically safe concepts for fieldbus are provided in IEC 60079-27.
This standard supplements and modifies the general requirements of IEC 60079-0, except as
indicated in Table 1. Where a requirement of this standard conflicts with a requirement of
IEC 60079-0, the requirements of this standard shall take precedence.
If associated apparatus is placed in the explosive gas atmosphere, it must be protected by an
appropriate type of protection listed in IEC 60079-0, and then the requirements of that method
of protection together with the relevant parts of IEC 60079-0 also apply to the associated
apparatus.
