Pertains specific requirements for the construction, testing and marking of electrical equipment, parts of electrical equipment and Ex components in the type of protection powder filling 'q', intended for use in explosive gas atmospheres.

This part of IEC60079 contains specific requirements for the construction, testing and marking of electrical equipment, parts of electrical equipment and Ex components in the type of protection powder filling “q”, intended for use in explosive gas atmospheres. NOTE1 Electrical equipment and Ex components protected by powder filling “q” can contain electronic circuits, transformers, protection fuses, relays, intrinsically safe electrical apparatus, associated electrical apparatus, switches, etc. NOTE2 Type of protection powder filling “q” provides Equipment Protection Level (EPL) Gb or Mb. This standard supplements and modifies the general requirements of IEC60079‑0 . Where a requirement of this standard conflicts with a requirement of IEC60079‑0 , the requirement of this standard takes precedence. This standard applies to electrical equipment, parts of electrical equipment and Ex components with: a rated supply current less than or equal to 16A; a rated supply voltage less than or equal to 1000V; a rated power consumption less than or equal to 1000W.
