Explosive environment Part 25. Flammable process fluids and electrical Process seal requirements between systems1 ScopeIf the process seal between the flammable process fluid and the electrical system fails, the process fluid will directly enter the field wiring system. This section of the Explosive Environment sets specific requirements for the process seal between flammable process fluids and electrical systems. This section specifies the assessment, manufacturing, and testing of single-process seal equipment, dual-process seal equipment, and additional secondary process seals. Claim. The requirements of this section do not apply to conduit sealing devices, cable entry devices and other involved in GB/T 3836 series or other standards Wiring sealing method. This section does not cover basic electrical safety and explosion-proof performance requirements, but may also apply to these devices. This section does not cover leaks.
