Title Explosive atmospheres - Part 10-2: Classification of areas - Combustible dust atmospheres
Project Number 21821
Abstract/Scope IEC 60079-10-2:2009 is concerned with the identification and classification of areas where explosive dust atmospheres and combustible dust layers are present, in order to permit the proper assessment of ignition sources in such areas. The principles of this standard can also be followed when combustible fibres or flyings may cause a hazard. This standard is intended to be applied where there can be a risk due to the presence of explosive dust atmospheres or combustible dust layers under normal atmospheric conditions. This first edition of IEC 60079-10-2 cancels and replaces the first edition of IEC 61241-10 published in 2004. The significant technical changes with respect to IEC 61241-10 are: - the hazards presented by dust have been clarified; - dust groups have been introduced; - Annex D explaining Equipment Protection Levels (EPLs) has been introduced; - 1 m of usual extent of zone 22 beyond zone 21 has been expanded to 3 m.

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of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
