SIST EN 300 019-1-4 V2.1.2:2006 is the Slovenian adoption of ETSI EN 300 019-1-4 V2.1.2, published by SIST for telecommunications equipment. It classifies the environmental conditions and severities for stationary use at non-weatherprotected locations. In practice, it is used to describe exposed outdoor conditions for equipment that is installed in place, including erection work, downtime, maintenance and repair.

What does SIST EN 300 019-1-4 V2.1.2:2006 specify?

SIST EN 300 019-1-4 V2.1.2:2006 specifies environmental classes for telecommunications equipment exposed to severe conditions at non-weatherprotected locations. The document keeps the focus on conditions that may harm equipment and on severities with a low probability of being exceeded, generally less than 1%.

The standard belongs to a multi-part ETSI series. Part 1 classifies environmental conditions, while Part 2 specifies the related environmental tests.

Class	What it covers
4.1	General non-weatherprotected locations, covering most of Europe
4.1E	Extended non-weatherprotected locations for Europe
4.2L	Extremely cold non-weatherprotected locations world-wide
4.2H	Extremely warm, dry non-weatherprotected locations world-wide

The document is organized into Scope, References, Definitions, Environmental classes, and Environmental conditions.

What are the key requirements of SIST EN 300 019-1-4 V2.1.2:2006?

SIST EN 300 019-1-4 V2.1.2:2006 classifies the outdoor environment by climate, biology, chemicals, mechanically active substances, mechanical stress, and earthquakes. The point is to help users match an installation site or a product design to a defined class before testing or deployment.

Climate and exposure classes

Clause 4 defines the four environmental classes and links them to the expected climate range. Class 4.1 is the general case, 4.1E extends the European climatic range, and 4.2L and 4.2H cover extreme cold and extreme warm-dry conditions.

Clause 5.1 then groups the climatic parameters that matter in practice: temperature, humidity, rain, pressure, solar radiation, air movement, condensation, precipitation, water splash, and icing or frost. This is the core checklist for site classification and for deciding whether equipment needs extra protection.

Biological, chemical, and mechanically active substances

Clauses 5.2, 5.3, and 5.4 cover biological conditions, chemically active substances, and mechanically active substances. The standard treats mould, fungus, rodents, salt mist, corrosive gases, sand, and dust as environmental stresses that can affect reliability, enclosure integrity, or maintenance intervals.

Clause 5.3 also identifies special classes for chemical exposure, and clause 5.4 does the same for sand and dust. In practice, these special classes let a user call out a more demanding single parameter when one hazard is more important than the others.

Mechanical and earthquake conditions

Clause 5.5 covers stationary vibration and non-stationary vibration, including shock type II. This matters for equipment mounted near machines, vehicles, or other vibration sources, and it points users to EN 300 019-2-4 for test severities and methods.

Clause 5.6 covers earthquake conditions where they are likely to occur. It uses a response spectrum approach and explains how Zero Period Acceleration (ZPA) is derived for equipment on rigid foundations or structures, with a separate note for buildings, pylons, poles, and other mounting cases.

What terms does SIST EN 300 019-1-4 V2.1.2:2006 define?

• Absolute humidity - the mass of water vapour in a given volume of dry air.
• Relative humidity - the ratio between actual water vapour pressure and saturation vapour pressure at the same temperature.
• Stationary use - equipment firmly mounted or permanently placed at one site, with only short handling periods during erection, downtime, maintenance, and repair.
• Non-weatherprotected location - a location where equipment is not protected from direct weather influences.
• Response Spectrum (RS) - a graphical way to describe the maximum response of oscillators to seismic base motion.
• Zero Period Acceleration (ZPA) - the high-frequency acceleration limit used in the earthquake description.
• ETSI - the European Telecommunications Standards Institute, the publisher of the underlying European Standard.

Who uses SIST EN 300 019-1-4 V2.1.2:2006?

SIST EN 300 019-1-4 V2.1.2:2006 is used by people who specify, design, test, and accept telecommunications equipment for exposed stationary sites. Typical users include equipment designers, environmental test engineers, quality managers, compliance staff, and buyers who need to state the site class before ordering or qualifying hardware.

It is especially relevant for outdoor telecom installations where the environment includes weather, contamination, vibration, or seismic risk. The keyword set in the document - environment, testing, equipment practice - reflects that practical use.

What changed in SIST EN 300 019-1-4 V2.1.2:2006 from the previous edition?

SIST EN 300 019-1-4 V2.1.2:2006 is the V2.1.2 version of the standard. The document history lists earlier publication as ETS 300 019-1-4, Amendment 1 to the first edition, V2.1.1, and V2.1.2.

Which standards are used with SIST EN 300 019-1-4 V2.1.2:2006?

• IEC 60721-3-4 - gives the base classification framework that the environmental classes are related to.
• IEC 60721-2-4 - supports the treatment of solar radiation and temperature.
• IEC 60068-2-27 - provides the shock test guidance referenced for vibration and shock terminology.
• IEC 60721-2-6 - supports the earthquake environment description.
• IEC 60068-3-3 - provides seismic test methods used in the earthquake clause.
• ETSI EN 300 019-1-3 - is the related class for stationary use at weatherprotected locations.
• ETSI EN 300 019-2-4 - specifies the test severities and test methods for these non-weatherprotected classes.
• ETSI ETR 035 - gives guidance and terminology for environmental engineering.

What does the SIST EN 300 019-1-4 V2.1.2:2006 document contain?

The document contains class descriptions, climatic limits, and the environmental parameters needed to classify a site or a product use case. Its figures include climatograms for the class ranges and an earthquake response spectrum.

Tables 1 to 5 set out the environmental conditions for climate, biology, chemical exposure, mechanically active substances, and mechanical loading. Table 6 and Table 7 give the earthquake parameters and the response spectrum coordinates used in the seismic description.

For users, this means the standard is not a product test method by itself. It is the classification basis that supports design decisions, environmental specification, and the selection of the matching test standard.

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:
