SIST EN 300 019-1-4 V2.1.1:2006 is the Slovenian adoption of ETSI EN 300 019-1-4 V2.1.1, a European Telecommunications Standard from ETSI. It classifies severe environmental conditions for telecommunications equipment used at stationary, non-weatherprotected locations. In practice, it helps users choose the right environmental class for exposed telecom installations and the related test approach.
What does SIST EN 300 019-1-4 V2.1.1:2006 specify?
SIST EN 300 019-1-4 V2.1.1:2006 defines environmental classes and the severities to which equipment may be exposed at non-weatherprotected locations. The standard focuses on conditions that are harmful to equipment and that are only rarely exceeded, generally with a probability below 1%.
The scope applies to equipment mounted for stationary use, including erection work, downtime, maintenance, and repair. That matters because the document covers not only normal operation, but also the periods when equipment is installed or serviced outdoors.
The document is organized into:
- Clause 3 - definitions
- Clause 4 - environmental classes
- Clause 5 - environmental conditions
- Annex A - bibliography
Clause 4 sets out four classes: 4.1, 4.1E, 4.2L, and 4.2H. Clause 5 then details the environmental parameters behind those classes.
What are the key requirements of SIST EN 300 019-1-4 V2.1.1:2006?
SIST EN 300 019-1-4 V2.1.1:2006 gives a practical classification scheme for exposed stationary telecom equipment. The main task for the reader is to match the installation site to the right class and then use the listed severities for design, testing, or acceptance.
Climatic classes and their use
Clause 4 divides the classes into general climatic conditions and extreme climatic conditions. Classes 4.1 and 4.1E cover most of Europe, while 4.2L and 4.2H are for extremely cold or extremely warm dry locations worldwide. This helps a designer or buyer decide whether a normal European outdoor site or a more severe climate must be considered.
Climatic conditions
Clause 5.1 lists the climatic parameters used to define the classes, including air temperature, humidity, rain intensity, temperature change rate, air pressure, solar radiation, air movement, condensation, precipitation, water from sources other than rain, and icing or frosting. The climatograms in Figures 1 and 2 show how the classes sit within temperature and humidity limits. In practice, this is the core reference for comparing a site climate with the intended equipment environment.
Biological and chemical exposure
Clause 5.2 covers biological conditions, including mould, fungus, rodents, and other animals harmful to products, with a special 4B2 class for some cases. Clause 5.3 covers chemically active substances such as salt mist, sulphur dioxide, hydrogen sulphide, chlorine, hydrochloric acid, hydrofluoric acid, ammonia, ozone, and nitrogen oxides. This matters where equipment is installed in coastal, urban, industrial, or contamination-prone areas.
Sand, dust, vibration, and shock
Clause 5.4 covers mechanically active substances such as sand and dust, including a special 4S3 class for 4.2H. Clause 5.5 specifies stationary vibration and non-stationary vibration, including shock type II. The note in 5.5 points readers to random vibration severities in ETSI EN 300 019-2-4 when that better reflects real use.
Earthquake conditions
Clause 5.6 applies when earthquakes are likely. It uses Response Spectrum (RS) and Zero Period Acceleration (ZPA) concepts and is written for equipment mounted at ground level or on rigid structures. For installations on pylons, poles, or other non-rigid supports, the structure must be considered in the test or a corrected RS must be determined.
What terms does SIST EN 300 019-1-4 V2.1.1:2006 define?
- Absolute humidity - the mass of water vapour in grammes associated with one cubic metre of dry air.
- Non-weatherprotected location - a location where the equipment is not protected from direct weather influences.
- Relative humidity - the ratio between water vapour pressure in moist air and saturation vapour pressure at the same temperature.
- Stationary use - equipment firmly mounted or permanently placed at a site, with only short handling during installation, downtime, maintenance, and repair.
- Response Spectrum (RS) - a graph showing the maximum response of single-degree-of-freedom 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 base acceleration.
Who uses SIST EN 300 019-1-4 V2.1.1:2006?
SIST EN 300 019-1-4 V2.1.1:2006 is used by telecom equipment designers, environmental test engineers, quality managers, and buyers who specify outdoor or exposed installations. It helps them classify the site environment, decide which class applies, and translate that into design assumptions or test conditions.
It is relevant for telecommunications equipment installed at stationary locations that are exposed to climate, contamination, vibration, dust, or earthquake risk. It is also useful when a site includes periods of erection work, maintenance, or repair.
What changed in SIST EN 300 019-1-4 V2.1.1:2006 from the previous edition?
The history records earlier ETS 300 019-1-4 edition 1 from February 1992 and Amendment 1 from June 1997, followed by ETSI EN 300 019-1-4 V2.1.1. It also records the publication as V2.1.1 in March 2003.

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
non-weatherprotected location: location at which the equipment is not protected from direct weather influences
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.
4 Environmental classes
The classes shown in parentheses, e.g. (4C3), may be selected for special applications.
These classes apply to a non-weatherprotected location.
These classes apply to locations:
- which are directly exposed to an open-air climate, including solar radiation, movement of the surrounding air,
precipitation and water jets; splashing water;
- where mould growth, or attacks by animals but excluding 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. It also applies to coastal areas;
NOTE 1: At locations in the immediate neighbourhood of industrial sources with chemical emissions either special
precautions must be taken or a special chemical class must be chosen.
- in areas with sand or dust sources, including urban areas;
NOTE 2: At locations in geographical areas with wind-driven sand or dust in air special precautions must be taken
or a special class for mechanically active substances must be chosen.
- where transmitted vibrations are experienced from machines or passing vehicles. Higher level shocks may be
experienced e.g. from adjacent machines.
NOTE 3: More severe mechanical conditions are to be expected for equipment intended for public use. Special
requirements should be stated for such equipment, e.g. protection against vandalism.
If earthquake conditions can be expected, the conditions stated in clause 5.6 apply.
Two groups of classes are considered:
- Classes 4.1 and 4.1E apply to general climatic conditions - applies to climatic conditions in most of Europe.
- Classes 4.2L and 4.2H apply to extreme climatic conditions. These classes should be considered
