Key to the Symbols
II Equipment group II applies to all equipment in areas which are potentially
endangered by an atmosphere capable of exploding, except in under-
ground mining operations and their above ground facilities which may be
endangered by mine gas and/or combustible types of dust.
(inside)/(outside)
Specifies the category/conditions according to which the inside (i) (i.e.
parts of the equipment in contact with the process gas flow) and the out-
side (o) of the equipment are classified, provided there is a difference
between them.
3 Category 3 comprises equipment which is so designed that it can be oper-
ated in agreement with the characteristic quantities (operating parameters)
specified by the manufacturer ensuring a normal degree of protection.
Equipment belonging to this category is intended for operation in areas
where it not needs to be expected that an explosive atmosphere occurs
due to gases, vapours, mists or raising dust, but when it occurs, then with
all probability only rarely and briefly.
Equipment belonging to this category ensures during normal operation the
necessary degree of safety.
G For areas with an atmosphere capable of exploding caused by gases,
vapours or mists in the air.
D For areas with an atmosphere capable of exploding caused by explosive
dusts.
