Explosive atmospheres. Equipment protection by type of protection "n"

Status : Current, Partially replaced, Superseded   Published : September 2010 Replaced By : BS EN IEC 60079-7:2015+A1:2018, BS EN IEC 60079-15:2019



This part of IEC 60079 specifies requirements for the construction, testing and marking for Group II electrical equipment with type of protection, "n" intended for use in explosive gas atmospheres. This standard applies to electrical equipment where the rated voltage does not exceed 15 kV r.m.s. a.c. or d.c.

This part of IEC 60079 is applicable to non-sparking electrical equipment and also to electrical equipment with parts or circuits producing arcs or sparks or having hot surfaces which, if not protected in one of the ways specified in this standard, could be capable of igniting a surrounding explosive gas atmosphere. This standard describes several different methods by which this can be achieved which may be combined with other methods described in IEC 60079‑0 .

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 requirement of this standard takes precedence.

Table 1
Relationship of this part to IEC 60079-0

[This table has been removed.]

Applies : this requirement of IEC 60079‑0 is applied without change.

Excluded : this requirement of IEC 60079‑0 does not apply.

Modified : this requirement of IEC 60079‑0 is modified as detailed in this standard.


The clause number in the above table is shown for information only. The applicable requirements of IEC 60079‑0 are identified by the clause title which is normative. This document was written against the specific requirements of IEC 60079‑0 (ed. 5.0). The clause numbers for the previous edition are shown for information only. This is to enable the General Requirements IEC 60079‑0 (ed. 5.0) to be used where necessary with this part of IEC 60079 . Where there were no requirements, indicated by “NR” or there is a conflict between requirements, the later edition requirements take precedence.


A non-incendive component is limited in use to the particular circuit for which it has been shown to be non-ignition capable and, therefore, cannot be separately assessed as complying with this standard.


Compliance with this standard does not imply any removal of, or lowering of the requirements of any other standard with which the electrical equipment complies.


This part of IEC 60079 supplements, and may enhance, the requirements for equipment for normal industrial applications. Where compliance with other IEC standards is indicated, such as IEC 60034 for motors and IEC 60598‑2 for luminaires, proving compliance to those standards is normally the responsibility of the manufacturer.


Type of protection “n” provides Equipment Protection Level (EPL) Gc. For further information, see IEC 60079‑0 .
