3 Definitions
For the purposes of the present document, the following terms and definitions apply:
absolute humidity: mass of water vapour in grammes which is associated with one cubic metre of dry air in an
air/water vapour mixture
air conditioning system: system that fully and automatically controls the climatic parameters air temperature and
humidity by heating, cooling, humidifying and dehumidifying
climate-controlling system: system that controls or influences climate, acting at least on one climatic parameter in one
direction
cooling system: system that controls or influences climate by decreasing the air temperature only
NOTE: This can decrease the absolute humidity.
forced ventilation system: system that controls or influences climate by introducing outdoor air into the room or
expelling air out of the room

SIST EN 300 019-1-3 V2.1.1:2006
 6 ETSI EN 300 019-1-3 V2.1.1 (2003-03)
heating system: system that controls or influences climate by increasing the air temperature only
NOTE: This can decrease the relative humidity.
relative humidity: ratio of the partial pressure of the water vapour in moist air at a given temperature, to the partial
pressure of the water vapour in saturated air at the same temperature
stationary use: The equipment is mounted firmly on the structure, or on mounting devices, or it is permanently placed
at a certain site. It is not intended for portable use - but short periods of handling during erection works, down time,
maintenance and repair at the location are included.
weatherprotected location: location at which the equipment is protected from direct weather influences
- totally weatherprotected location (enclosed location):
- direct weather influences are totally excluded,
- partly weatherprotected location (sheltered location):
- direct weather influences are not completely excluded.
4 Environmental classes
The classes shown in parentheses, e.g. (3C1), may be selected for special applications.
4.1 Class 3.1: Temperature-controlled locations
Class 3.1 is a combination of classes 3K3/3Z2/3Z4/3B1/3C2(3C1)/3S2/3M1 in IEC standard 60721-3-3 [1].
The climatogram is shown in figure 1 in clause 4.1.
Seismic environment: zone 4 as defined in IEC 60721-2-6 [3]. Option zone 4 (modified Mercalli scale ≥ 9): if earthquake
conditions are specified by the customer, the conditions stated in clause 5.6 apply.
This class applies to a permanently temperature controlled enclosed location. Humidity is usually not controlled. The
climatogram is shown in figure 1.
Heating, cooling, forced ventilation and humidification are used as necessary to maintain the required
conditions - especially where there is a significant difference between the room environment and the external ambient.
The climate-controlling systems could be periodically switched on or off but extremely high or low temperatures are
prevented.
This class applies to locations:
- where installed equipment may be exposed to solar radiation and to heat radiation. It may also be exposed to
movements of the surrounding air due to draughts in buildings. They are not subjected to condensed water,
precipitation, water from sources other than rain or icing;
- without particular risks of biological attacks. This includes protective measures, e.g. special product design, or
installations at locations of such construction that mould growth and attacks by animals, etc. are not probable;
- with normal levels of contaminants experienced in urban areas with industrial activities scattered over the
whole area and/or with heavy traffic;
- without special precautions to minimize the presence of sand or dust, but which are not situated in proximity to
sources of sand or dust;
- with insignificant vibration and shock.

The conditions of this class may be found in:
- normal living or working areas, e.g. living rooms, rooms for general use (theatres, restaurants);
- offices;
- shops;
- workshops for electronic assemblies and other electrotechnical products;
- telecommunication centres;
- storage rooms for valuable and sensitive products.

Values outside this field have a probability of occurrence of
less than 10% (see IEC 60721-3-0).
Exceptional climatic limits
Normal climatic limits: Values outside these limits have a probability of
occurrence of less than 1%.

NOTE: Exceptional conditions may occur following the failure of the temperature controlling system. This is
described as 3.1E in the tables but it should be noted that there is no separate class 3.1E.

4.2 Class 3.2: Partly temperature-controlled locations
This class is a combination of classes 3K5/3Z2/3Z4/3B2/3C2(3C1)/3S3/3M2 in IEC standard 60721-3-3 [1].
Seismic environment: zone 4 as defined in IEC 60721-2-6 [3]. Option zone 4 (modified Mercalli scale ≥ 9): if earthquake
conditions are specified by the customer, the conditions stated in clause 5.6 apply.
This class applies to an enclosed location having neither temperature nor humidity control. The climatogram is shown
in figure 2.
Heating may be used to raise low temperatures especially where there is a significant difference between the conditions
of this class and the open-air climate. Building construction is designed to avoid extremely high temperatures.

This class 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. 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;
- certain workshops;
- buildings in factories and industrial process plants;
- unattended equipment stations;
- certain telecommunication buildings;
- ordinary storage rooms for frost resistant products and farm buildings, etc.

4.3 Class 3.3: Not temperature-controlled locations
This class is a combination of classes 3K6/3Z2/3Z4/3Z7/3B2/3C2(3C1)/3S3/3M2 in IEC 60721-3-3 [1].
Seismic environment: zone 4 as defined in IEC 60721-2-6 [3], Option zone 4 (modified Mercalli scale ≥ 9): if earthquake
conditions are specified by the customer, the conditions stated in clause 5.6 apply.
This class applies to a weatherprotected location having neither temperature nor humidity control. The location may
have openings directly to the open air, i.e. may be only partially-weather protected. The climatogram is shown in
figure 3.
The climatic conditions of this class may be affected to a varying extent by the conditions of the open-air climate and
the construction of the building.
This class applies to locations:
- where installed equipment may be exposed to solar radiation and temporarily to heat radiation. It may also be
exposed to movements of the surrounding air due to draughts e.g. through doors, windows or other openings.
It may be subjected to condensed water, to water from sources other than rain and to icing. It may temporarily
be subjected to limited wind-driven precipitation, including snow;
