This applies to locations:
– where installed equipment may be exposed to solar radiation and heat radiation. They may also be
exposed to movements of the surrounding air due to draughts in buildings, e.g. through open
windows. They may be subjected to condensed water and to water from sources other than rain and
icing. They are not subjected to precipitation;
– where mould growth or attacks by animals, except termites, may occur;
– with normal levels of contaminants experienced in urban areas with industrial activities scattered
over the whole area and/or with heavy traffic;
– In close proximity to sources of sand or dust;
– with vibration of low significance, e.g. for products fastened to light supporting structures subjected
to negligible vibrations.
The conditions of this class may be found in:
– entrances and staircases of buildings;
– garages;
– cellars;
