Title Explosive atmospheres - Part 15: Equipment protection by type of protection "n"
Project Number 21940
Abstract/Scope IEC 60079-15:2010 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 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. The significant technical changes with respect to the previous edition are as follows: - addition of equipment protection levels; - removal of the requirements for energy-limited 'nL' and associated energy limited apparatus '[nL]'; - removal of the requirements for encapsulated Devices 'nC'; - requirements for electrical connections expanded and clarified; - requirements for electrical connections expanded and clarified; - requirements for luminaire ballasts expanded and clarified; - requirements for evaluation and testing of motor rotors clarified; - 15 kV limit for equipment protection by type of protection 'n' added; - spacing requirement for voltages above 10 kV modified; - requirements for restricted breathing enclosures modified; - modification to requirements for motor rotors and stators; - addition of Annex A (informative); - and undated references to IEC 60079-0 included.

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn

(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
