AS/NZS 60079.10.2:2016

Abstract

Adopts IEC 60079-10-2, Ed.2.0 (2015) to specify requirements for the identification and classification of areas where explosive dust atmospheres may be present, in order to permit the proper assessment of ignition sources in such areas.

Scope

This part of IEC 60079 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 atmospheric conditions
(see Note 1).
