SIST EN 300 019-1-3 V2.2.2:2006 is the Slovenian standard identical with EN 300 019-1-3 Version 2.2.2, published by SIST. It classifies environmental conditions and their severities for telecommunications equipment mounted for stationary use at weatherprotected locations, so designers, testers, quality managers, and buyers can match equipment to the site environment. The severities are intended to be levels with a low probability of being exceeded, generally less than 1%.
What does SIST EN 300 019-1-3 V2.2.2:2006 specify?
SIST EN 300 019-1-3 V2.2.2:2006 specifies the environmental classes for stationary telecommunications equipment at weatherprotected locations and the severity limits associated with those classes. It tells you what kind of temperature, humidity, contamination, vibration, and earthquake exposure to expect in different site types.
The document is organized into these main parts:
- Clause 1 - Scope
- Clause 2 - References
- Clause 3 - Definitions and abbreviations
- Clause 4 - Environmental classes
- Clause 5 - Environmental conditions
- Annex A - Bibliography
Clause 4 sets out six classes, from 3.1 to 3.6, and Clause 5 gives the environmental parameters that go with them. In practice, that means the standard is both a site classification document and a basis for deciding what environmental testing or design margin is appropriate.
What are the key requirements of SIST EN 300 019-1-3 V2.2.2:2006?
The document starts from the site class, not from a generic equipment rating
SIST EN 300 019-1-3 V2.2.2:2006 divides stationary use at weatherprotected locations into six environmental classes in Clause 4: temperature-controlled locations, partly temperature-controlled locations, not temperature-controlled locations, sites with heat-trap, sheltered locations, and telecommunication control room locations. Special classes in parentheses, such as (3C1), may be selected for special applications.
That matters because the standard is meant to be matched to the real installation site. A product for a controlled control room is not automatically suitable for an unattended shelter, even if both are indoors.
Each class describes a real type of location
Clauses 4.1 to 4.6 describe the intended site conditions for each class. The text links each class to typical places such as offices, workshops, garages, cellars, sheds, open telephone booths, telecommunication centres, and dedicated control rooms.
In practice, this helps a specifier decide whether the site is temperature controlled, partly controlled, exposed to solar loading, subject to heat-trap effects, or only sheltered from direct weather. The classification also makes the expected exposure easier to communicate in procurement and qualification documents.
Climate is handled through a parameter table and climatograms
Clause 5.1 and Table 1 define the climate parameters for classes 3.1 to 3.6, including air temperature, relative and absolute humidity, air pressure, solar radiation, heat radiation, movement of surrounding air, condensation, wind-driven rain or snow, water from sources other than rain, and icing. Figures 1 to 6 show the climatograms for the six classes.
For users, this means the standard is not just a label. It gives a structured checklist of environmental loads that can affect housing design, ventilation, sealing, condensation control, and material choice.
Biological, chemical, and dust exposure are separated into their own clauses
Clauses 5.2 to 5.4 deal with biological conditions, chemically active substances, and mechanically active substances. The chemical tables distinguish the ordinary classes from the special chemical classes 3C1 and 3C3, and they treat gases such as sulphur dioxide, hydrogen sulphide, chlorine, hydrochloric acid, hydrofluoric acid, ammonia, ozone, and nitrogen oxides.
That matters in practice because the environmental risk is not only temperature. A coastal site, a road-side site, or a plant building may need attention to salt mist, industrial gases, mould, rodents, sand, or dust even when the temperature is moderate.
Mechanical exposure includes vibration, shock, and a practical note on random vibration
Clause 5.5 and Table 5 define stationary vibration and non-stationary vibration, including shock, for the different class groups. The note under Table 5 says random vibration is often a more realistic description than sinusoidal vibration and points to ETSI EN 300 019-2-3 for random-vibration severities.
In practice, this tells engineers not to treat vibration as an afterthought. If the equipment sits on a structure, near traffic, or close to machines, the mechanical environment can drive enclosure design, mounting choice, and test selection.
Earthquake conditions are specified through response-spectrum logic
Clause 5.6 explains earthquake conditions using a Response Spectrum (RS) approach and the Zero Period Acceleration (ZPA) concept. It also gives the parameter severities used for classes 3.1 to 3.6 and shows the corresponding response spectrum in Figure 7 and Table 7.
This is important because seismic design is not reduced to one simple acceleration number. The standard helps users define the mounting motion expected during an earthquake and use that definition consistently in design and testing.
What terms does SIST EN 300 019-1-3 V2.2.2:2006 define?
- Absolute humidity - the mass of water vapour in one cubic metre of dry air in an air and water vapour mixture.
- Air conditioning system - a system that automatically controls temperature and humidity by heating, cooling, humidifying, and dehumidifying.
- Climate-controlling system - a system that influences climate by acting on at least one climatic parameter in one direction.
- Cooling system - a system that lowers air temperature only, which can also reduce absolute humidity.
- Heating system - a system that raises air temperature only, which can also reduce relative humidity.
- Relative humidity - the ratio of the water-vapour partial pressure in moist air to the saturation pressure at the same temperature.
- Stationary use - equipment fixed to a structure or site, including short periods of handling during erection, downtime, maintenance, and repair.
- Weatherprotected location - a location where direct weather influences are fully excluded or only partly excluded.
- Response Spectrum (RS) - the graph used in seismic work to show the maximum response of oscillators as a function of frequency during transient base motion.
- Zero Period Acceleration (ZPA) - the high-frequency asymptotic acceleration of the response spectrum, representing the largest peak value of the base motion.
Who uses SIST EN 300 019-1-3 V2.2.2:2006?
SIST EN 300 019-1-3 V2.2.2:2006 is used by telecommunications equipment designers, environmental test engineers, quality managers, site planners, installers, and purchasers. They use it to classify the intended installation, select environmental design margins, and decide which conditions need to be covered in qualification or acceptance planning.
It is especially relevant for:
- telecommunications centres and control rooms
- offices, workshops, garages, and storage rooms where telecom equipment is installed
- shelters, sheds, shacks, and other partly protected locations
- unattended equipment stations and similar stationary installations

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 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;
ETSI
7 ETSI EN 300 019-1-3 V2.2.2 (2004-07)
- 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.

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.

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.
