SIST EN 300 019-1-5 V2.1.4:2006 is the Slovenian adoption of ETSI EN 300 019-1-5, published by SIST. It defines environmental condition classes for telecommunications equipment installed in ground vehicles, covering the severities of climate, biological, chemical, fluid, dust, and mechanical exposure. Engineers use it to choose the right environmental class for equipment in use, whether it is permanently or temporarily installed.

What does SIST EN 300 019-1-5 V2.1.4:2006 specify?

SIST EN 300 019-1-5 V2.1.4:2006 specifies the environmental classes and severities that apply to telecommunications equipment in ground vehicles. It focuses on severe conditions that may damage equipment and on conditions that are only rarely exceeded.

The document is organized around the scope, references, definitions, two environmental classes, and the detailed environmental conditions that support those classes. Annex A provides a climate application summary for the two classes.

What are the key requirements of SIST EN 300 019-1-5 V2.1.4:2006?

SIST EN 300 019-1-5 V2.1.4:2006 is built around two installation classes: 5.1 Protected installation and 5.2 Partly protected installation. In practice, the class you choose depends on how well the equipment is sheltered inside the vehicle and on the environment it will face during use.

Class selection in Clause 4

Clause 4 combines the environmental parameter groups from IEC 60721-3-5 into the two installation classes. Class 5.1 covers protected installations such as weatherprotected and heated locations, plus some ventilated compartments and engine compartments under specified climate conditions. Class 5.2 extends the coverage to more exposed non-weatherprotected use, including heated compartments after warm-up and some engine-compartment applications.

This matters because the class determines how severe the expected environment is. If the equipment is mounted where rain, sunlight, salt spray, dust, or vibration are more likely, the more exposed class is the better match.

Climatic and biological conditions in Clause 5

Clause 5 groups the relevant environmental factors into climatic, biological, chemical, fluid, mechanically active, and mechanical conditions. The climatic part covers temperature change, humidity, low pressure, air movement, precipitation, solar radiation, heat radiation, water from sources other than rain, and wetness. The biological part covers mould, fungus, rodents, and other harmful animals except termites.

For the reader, this means the standard is not just about temperature. It also helps you decide whether the installation site needs protection against condensation, wet surfaces, wind, sunshine through windows, and biological growth.

Chemical substances and fluids

Clause 5 also covers chemically active substances and contaminating fluids. The standard separates the general classes from the special chemical class 5C3 and from the engine-compartment fluid class 5F2.

In practice, this tells you when normal urban contamination is assumed and when stronger protection or a more severe class is needed because of salt, industrial pollutants, oil, hydraulic fluid, brake fluid, fuel, or battery electrolyte.

Mechanical exposure

Clause 5 includes mechanically active substances and mechanical conditions. Class 5S1 is tied to vehicle cab conditions for sand and dust, while the mechanical classes 5M2 and 5M3 cover vibration, shock, and stone impact.

This is important for mounting decisions. The standard distinguishes better-protected road vehicles and installations from harsher use in rough roads, tracked vehicles, low-mass vehicles, and externally mounted equipment.

Annex A

Annex A gives a practical summary showing how classes 5.1 and 5.2 apply across the climate areas defined in IEC 60721-2-1. That helps the user match the vehicle location and the climate zone before moving on to testing or specification work.

What terms does SIST EN 300 019-1-5 V2.1.4:2006 define?

• Absolute humidity - the mass of water vapour associated with one cubic metre of dry air.
• Externally mounted - equipment fixed outside the vehicle, without protection from external influences.
• Internally mounted - equipment mounted inside a vehicle compartment that gives some environmental protection.
• Relative humidity - the ratio of water vapour pressure in moist air to saturation pressure at the same temperature.
• Weatherprotected location - a place where the vehicle is shielded from direct weather influences and is still reasonably ventilated.
• 5M2 - the mechanical class for road vehicles on well-developed roads, including vibration and stone impact conditions.
• 5M3 - the mechanical class for rougher vehicle use, including tracked vehicles, overland vehicles, and harder shock conditions.

Who uses SIST EN 300 019-1-5 V2.1.4:2006?

SIST EN 300 019-1-5 V2.1.4:2006 is used by telecommunications equipment designers, environmental test engineers, quality managers, and procurement teams. It helps them classify vehicle-mounted equipment, set environmental expectations, and decide what protection level is needed.

It is relevant for equipment in road vehicles, trains, fork lift trucks, self-propelled machines, and other ground vehicles where telecom equipment is installed in protected, partly protected, or exposed locations.

Which standards are used with SIST EN 300 019-1-5 V2.1.4:2006?

The document refers to several supporting standards and related parts:

• ETSI ETR 035 - guidance and terminology for environmental engineering.
• IEC 60721-3-5 - the base classification system used for the combined environmental classes and the 5M2/5M3 mechanical classes.
• IEC 60721-2-1 - the climate-area classification used in Annex A.
• IEC 60068-2-27 - shock test guidance used for the shock response spectrum terminology.
• ETSI EN 300 019 Part 1-0 - the general overview of Part 1.
• ETSI EN 300 019 Part 2 - the companion part that specifies recommended test severities and test methods.

What does the SIST EN 300 019-1-5 V2.1.4:2006 document contain?

The document contains the class definitions, environmental parameter tables, and the explanatory notes needed to apply the classes in vehicle installations. Tables 1 to 6 cover climate, biology, chemical substances, contaminating fluids, mechanically active substances, and mechanical conditions.

It also includes notes that explain how to interpret installation situations such as engine compartments, ventilated compartments, wet surfaces, solar loading, road salts, and sand exposure. Annex A adds a climate application summary that supports specification and later testing work.

4 Environmental classes
The classes shown in parentheses, e.g. (5S1), may be selected for special applications.
4.1 Class 5.1: Protected installation
This class is a combination of classes 5K2/5B2/5C2(5C3)/5F1(5F2)/5S2(5S1)/5M2 or 5M3 in IEC 60721-3-5 [2].
This class applies to equipment in vehicles used at weatherprotected and heated locations covered by world-wide
open-air climates excluding extremely warm dry climates.
At non-weatherprotected locations this class applies to equipment in ventilated compartments and in the engine
compartments of vehicles powered by electric motors in climatic conditions with normal rain intensities but excluding
extremely cold, cold, cold temperate and extremely warm dry climates.
NOTE 1: For some environmental parameters (low air temperature, high air temperature) this class also covers
externally mounted equipment.
NOTE 2: A survey of applications in different climates is given in Annex A. Climatic conditions for different areas
are defined in IEC 60721-2-1 [3].
This class applies to:
- equipment subjected to heat from heating elements and solar radiation through windows. The vehicle may be
moved between cold, non-weatherprotected and warm, weatherprotected conditions. The equipment may also
be subjected to dripping water and conditions of wet mounting surfaces. Engine compartments may be
subjected to the ingress of water and snow;
- areas and conditions where mould growth and attacks by animals, except termites, may occur;
- equipment internally mounted in partly open compartments and in engine compartments which may be
subjected to the ingress of road salts;
- locations with normal levels of contaminants experienced in urban areas with industrial activities scattered
over the whole area and/or with heavy traffic;
NOTE 3: In areas with industrial sources emitting high quantities of chemical pollutants either special precautions
must be taken or the special IEC chemical class 5C3 must be chosen.
- compartments where contaminating fluids are not expected;
NOTE 4: If the equipment is exposed to contaminating fluids either the special precautions must be taken or the
special IEC class 5F2 must be chosen.
- equipment not protected from sand and dust on vehicles not used in desert areas.
NOTE 5: In a vehicle cab which is mainly protected from sand the special IEC class 5S1 may be chosen.
Class 5.1 also includes one of the following mechanical conditions as appropriate:
- Class 5M2: All types of road vehicles used in areas with well-developed road systems except tracked vehicles,
motorcycles, scooters and other vehicles with low mass. The equipm
