IEC 60079-10-2:2015

IEC 60079-10-2:201 5 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.  In  this standard,  explosive dust atmospheres  and combustible  dust layers are treated    separately.    In Clause 4, area classification for  explosive dusts  clouds is described, with dust layers acting as one     of the possible  sources  of release. In Clause  7  other general  considerations for  dust layers are described. The examples  in this standard are based on a system of effective housekeeping being implemented in the plant    to    prevent  dust layers from accumulating. Where effective housekeeping   is not  present, the area   classification   includes  the possible  formation of  explosive dust  clouds from dust layers. The principles   of this standard can  also  be followed when combustible fibres or flyings might 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  atmospher ic  conditions. Please  refer  to the foreword of the document  for a detailed listing of the  significant   technical changes from the previous edition.
