Scope

This document specifies the structure and test requirements for intrinsically safe devices used in explosive environments, as well as associated devices connected to intrinsically safe circuits used in explosive environments.
The explosion-proof types specified in this document are applicable to electrical equipment whose circuits themselves will not ignite the surrounding explosive environment.
This document is also applicable to electrical equipment or its components used in non-explosive environments or protected by another explosion-proof type listed in GB/T 3836.1—2021, as long as the intrinsically safe performance of the circuits in the explosive environment depends on the design and structure of the electrical equipment or its components. The circuits exposed to explosive environments can be evaluated for their suitability for such environments using this document.
The requirements for intrinsically safe systems are specified in GB/T 3836.18.
This document supplements and modifies the general requirements of GB/T 3836.1—2021, except for the cases listed in Table 1. When the requirements of this document conflict with those of GB/T 3836.1—2021, the requirements of this document shall take precedence.
When the requirements of this document apply to both intrinsically safe devices and associated devices, the term "device" is used in this document.
This document is only applicable to electrical equipment, so the term "equipment" used in this document generally refers to "electrical equipment".
Associated devices placed in explosive environments shall be protected by one of the explosion-proof types specified in GB/T 3836.1—2021. In this case, the explosion-proof type requirements and related parts specified in GB/T 3836.1—2021 also apply to associated devices.
