Provides guidance on the classification of areas associated with several finishing processes, fruit ripening rooms, several batch-type processes and ammonia systems. It includes specific examples of classification for the aforementioned areas. To be read in conjunction with AS/NZS 2430.3.1:1997.

This Standard provides examples of area classification for areas associated with specialised processes other than those covered by Parts 3.2 to 3.8 of AS/NZS 2430.3. It is part of the AS/NZS 2430.3 series, which recommends the classification of several commonly occurring situations and should be read in conjunction with AS/NZS 2430.3.1.
