SIST ETS 300 019-1-4 E1:2006 is the Slovenian adoption of ETS 300 019-1-4 Edition 1 from ETSI. It classifies environmental conditions for telecommunications equipment intended for stationary use at non-weatherprotected locations, so engineers can choose an environmental class and understand the exposure the equipment may face.

What does SIST ETS 300 019-1-4 E1:2006 specify?

SIST ETS 300 019-1-4 E1:2006 specifies one environmental class for telecommunications equipment exposed to outdoor-like conditions at stationary sites. It focuses on severe conditions that may damage equipment and on severities that are rarely exceeded, generally at the 1% level or below.

The standard applies to equipment that is mounted for stationary use, including periods of erection work, downtime, maintenance and repair at non-weatherprotected locations. Annex A gives background on open-air climates and the statistical basis used for the climatic severities.

• Annex A, informative

What are the key requirements of SIST ETS 300 019-1-4 E1:2006?

SIST ETS 300 019-1-4 E1:2006 is a classification standard, so its main job is to define the environmental profile that equipment must tolerate. In practice, it tells you which site conditions to use when specifying, designing or testing telecom equipment for exposed stationary use.

Environmental class in Clause 4

Clause 4 defines Class 4.1 for non-weatherprotected locations and Class 4.1E as the extended version. Class 4.1 applies to many ETSI countries, while Class 4.1E covers all ETSI countries.

Clause 4 also shows how these classes combine several IEC Publication 721-3-4 classes. This matters because the class number is a shorthand for a full environmental profile, not just a single climate condition.

Climatic conditions in Clause 5.1

Clause 5.1 gives the climatic conditions that define the class, including low and high air temperature, humidity, rain, solar radiation, air movement, condensation, precipitation, water splashing and icing or frosting. Figure 1 presents the climatogram for Classes 4.1 and 4.1E.

For users, this is the core input for enclosure selection, component rating and outdoor installation limits.

Biological conditions in Clause 5.2

Clause 5.2 covers biological exposure such as mould, fungus, rodents and other animals, excluding termites. This helps readers check whether materials, seals and cable entries need protection against growth or attack.

Chemically active substances in Clause 5.3

Clause 5.3 sets levels for chemically active substances such as salt mist, sulphur dioxide, hydrogen sulphide, chlorine, hydrochloric acid, hydrofluoric acid, ammonia, ozone and nitrogen oxides. The table also includes a special class 4C3 for some chemical exposures.

In practice, this clause is used to judge corrosion risk, especially for coastal, urban and industrial areas, and to decide when extra protection or a different chemical class is needed.

Mechanically active substances in Clause 5.4

Clause 5.4 covers sand and dust, including both suspension and sedimentation. This tells designers and buyers when filtration, sealing, cleaning intervals or dust protection should be considered.

Mechanical conditions in Clause 5.5

Clause 5.5 addresses stationary vibration and non-stationary vibration including shock. Figure 2 gives the model shock response spectrum used for the class.

That matters for mounting design, transport to site and resistance to vibration from nearby machines or passing vehicles.

What terms does SIST ETS 300 019-1-4 E1:2006 define?

• Stationary use - Equipment is fixed to a structure, mounting device or site, with only short handling during erection, downtime, maintenance or repair.
• Non-weatherprotected location - A site where equipment is directly exposed to weather influences.
• Environmental class - A named set of environmental conditions and severities used to describe the service environment.
• Class 4.1 - The environmental class for non-weatherprotected locations used for many ETSI countries.
• Class 4.1E - The extended environmental class for non-weatherprotected locations covering all ETSI countries.
• 1% (99%) fractile - The statistical basis used for the severities, meaning the level is expected to be exceeded only rarely.

Who uses SIST ETS 300 019-1-4 E1:2006?

SIST ETS 300 019-1-4 E1:2006 is used by telecom equipment designers, environmental test engineers, quality managers, procurement teams and site planners. It helps them describe the installation environment, choose the right class for a product or site, and check whether equipment is suitable for outdoor or exposed stationary use.

It is also useful for manufacturers and buyers of telecommunications terminals and related equipment when they need a common way to describe climate, contamination, dust, vibration and shock exposure.

Which standards are used with SIST ETS 300 019-1-4 E1:2006?

The standard refers to several companion documents:

• ETR 035 - Provides environmental engineering guidance and terminology.
• IEC Publication 721-3-4 - Gives the source class for stationary use at non-weatherprotected locations.
• IEC Publication 721-2-4 - Covers solar radiation and temperature.
• IEC Publication 721-2-1 - Covers temperature and humidity.
• IEC Publication 68-2-27 - Defines Test Ea: Shock.
• ETS 300 019-1 - The companion part on classification of environmental conditions.
• ETS 300 019-2 - The companion part on environmental test requirements.

What does the SIST ETS 300 019-1-4 E1:2006 document contain?

The document contains a short classification system supported by tables and figures. Tables 1 to 5 set out the climatic, biological, chemically active, mechanically active and mechanical conditions for Classes 4.1 and 4.1E.

Figure 1 gives the climatogram for the class, and Figure 2 shows the model shock response spectra used for non-stationary vibration including shock. Annex A adds the statistical and climatic background that explains how the class severities were chosen.

Foreword
This multi-part European Telecommunication Standard (ETS) has been produced by the Equipment
Engineering (EE) Technical Committee of the European Telecommunications Standards Institute (ETSI).
This standard is concerned with environmental conditions and environmental tests for telecommunications
equipment and comprises two main parts, each with subdivisions:
- ETS 300 019-1: "Classification of environmental conditions".
This part of the standard, Part 1, specifies different standardised environmental classes covering
climatic and biological conditions, chemically and mechanically active substances and mechanical
conditions during storage, transportation and in use.
- ETS 300 019-2: "Specification of environmental tests".
This part of the standard specifies the test requirements for the different environmental classes.
Each part of the standard is divided into sub-parts. Sub-part 1-0 will form a general overview of Part 1.
This sub-part, Sub-part 1-4, deals with stationary use at non-weatherprotected locations.
This part of the standard (Part 1) was submitted to Public Enquiry as prETS 300 019 Part B. The original
Part A is to be published as ETSI Technical Report ETR 035 entitled: "Equipment Engineering (EE);
Environmental engineering Guidance and terminology".
Annex A to this sub-part is informative.

1 Scope
The purpose of this sub-part is to define a class of environmental conditions and their severities to which
equipment may be exposed. Only severe conditions, which may be harmful to the equipment, are included.
The severities specified are those which will have a low probability of being exceeded; generally less than
1 %.
For completeness the IEC grouping of open-air climates is given in Annex A.
This sub-part applies to equipment mounted for stationary use including periods of erection work, down
time, maintenance and repair at non-weatherprotected locations defined in Clause 5.
2 Normative references
This ETS contains, by dated or undated reference, provisions from other publications. For dated
references, subsequent amendments to, or revisions of any of these publications apply to this document
only when incorporated into it by amendment or revision. For undated references, the latest version of the
publication referred to applies.

3 Definitions
In this sub-part of this standard, the following definitions apply:
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.
Non-weatherprotected location: A location at which the equipment is not protected from direct weather
influences.
4 Environmental class
The classes shown in parentheses, e.g. (4C3), may be selected for special applications.
4.1 Class 4.1: Non-weatherprotected locations
Class 4.1E: Non-weatherprotected locations - extended
Class 4.1 applies to many ETSI countries. Class 4.1 E covers all ETSI countries.
Class 4.1 is a combination of classes 4K2/4Z5/4Z7/4B1/4C2(4C3)/4S2/4M5 in IEC Publication 721-3-4 [2].
Class 4.1E is a combination of classes 4Z5/4Z7/4B1/4C2(4C3)/4S2/4M5 in IEC Publication 721-3-4 [2]
and the climatic conditions are given in subclause 5.1.
This class applies to a non-weatherprotected location. The climatogram is shown in figure 1 in subclause
5.1.
Page 8
ETS 300 019-1-4: February 1992
This class applies to locations:
- which are directly exposed to an open-air climate, including solar radiation, movement of the
surrounding air, precipitation and water jets;
- 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: 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;
- where transmitted vibrations are experienced from machines or passing vehicles. Higher level
shocks may be experienced e.g. from adjacent machines.
NOTE: 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.

NOTE 1:  In cloudless nights an object exposed to atmospheric radiation
will radiate more heat than it receives off the surface, compared
to the ambient air temperature. In practice (under extreme
conditions) the surface may come down to a temperature in the
order of 10 C to 20 C below ambient air temperature, when the
ambient temperature ranges from +20 C to 30 C. (For further
information see IEC Publication 721 2 4 [3]).
