SIST EN 300 019-1-5 V2.1.2:2006 is the Slovenian version of ETSI EN 300 019-1-5 for telecommunications equipment in ground vehicles. It classifies the environmental conditions and severities that such equipment may face in use, especially the severe conditions that can damage equipment. Engineers, test labs, and buyers use it to choose the right environmental class for vehicle-mounted telecom equipment and to see which conditions should be considered in qualification.

What does SIST EN 300 019-1-5 V2.1.2:2006 specify?

SIST EN 300 019-1-5 V2.1.2:2006 defines environmental classes for equipment permanently or temporarily installed in ground vehicles. It focuses on severe conditions only, and the stated severities are those with a low probability of being exceeded, generally less than 1%.

The document is organized into scope, references, definitions, environmental classes, and environmental conditions. Annex A gives a normative summary of how classes 5.1 and 5.2 apply to different climate areas, and Annex B is a bibliography.

What are the key requirements of SIST EN 300 019-1-5 V2.1.2:2006?

SIST EN 300 019-1-5 V2.1.2:2006 does not prescribe a test program by itself. Instead, it defines the environmental class to be used for equipment in ground vehicles, and the class then drives later test selection and severity choice.

The two main environmental classes

• Class 5.1, Protected installation - for equipment in weatherprotected and heated locations, and for some non-weatherprotected uses with more limited exposure. In practice, this is the class for equipment that has some shielding from weather and contamination.
• Class 5.2, Partly protected installation - for equipment with greater exposure at non-weatherprotected locations, including externally mounted or partly open installations. In practice, this means a tougher environment choice when rain, splash, or direct exposure is more likely.

Climatic conditions

The climatic table covers low and high air temperature, temperature change, humidity, low air pressure, air movement, rain, solar radiation, heat radiation, water from other sources, and wetness. For a user, this is the core basis for deciding whether the installation is exposed to cold starts, heating, sun through windows, rain, or wet surfaces.

Biological, chemical, and contaminating exposure

The document includes biological conditions such as mould and animals, chemical active substances such as sea salt, road salts, sulphur dioxide, ozone, and ammonia, and contaminating fluids such as oils, brake fluid, coolant, fuel, and battery electrolyte. In practice, this helps a designer decide whether the vehicle location needs special protection or whether a more severe class such as 5C3 or 5F2 should be considered.

Mechanical exposure

Mechanical conditions are given for vibration, shock, and impact from foreign bodies, stones. The document distinguishes 5M2 and 5M3 according to road quality, vehicle type, and installation. That matters because the same equipment may need different mechanical qualification depending on whether it is used in well-developed road systems or in rougher conditions.

Annex A as a selection aid

Annex A links the classes to climate areas from IEC 60721-2-1. This helps users map a vehicle installation to the right climate context instead of choosing a class by guesswork.

What terms does SIST EN 300 019-1-5 V2.1.2:2006 define?

SIST EN 300 019-1-5 V2.1.2:2006 defines several terms that shape how the classes are applied.

• Absolute humidity - the mass of water vapour in one cubic metre of dry air.
• Externally mounted - equipment mounted outside the vehicle and not protected from external influences.
• Internally mounted - equipment mounted inside the vehicle in a compartment that gives some environmental protection.
• Relative humidity - the ratio of water vapour partial pressure in moist air to that in saturated air at the same temperature.
• Weatherprotected location - a location where the vehicle is protected from direct weather influences.
• Ground vehicle installations - the use case covered by the document: equipment installed in vehicles.

Who uses SIST EN 300 019-1-5 V2.1.2:2006?

SIST EN 300 019-1-5 V2.1.2:2006 is used by telecommunications equipment designers, environmental engineers, test laboratories, and quality teams. It is also relevant to vehicle integrators and buyers who need to specify whether telecom equipment will be installed in a cab, compartment, engine compartment, or on the outside of a vehicle. The standard is especially useful when writing environmental qualification plans or deciding which installation class applies.

What changed in SIST EN 300 019-1-5 V2.1.2:2006 from the previous edition?

SIST EN 300 019-1-5 V2.1.2:2006 is the version published as ETSI EN 300 019-1-5 V2.1.2, and the history shows it replaces ETS 300 019-1-5. The document history lists the earlier edition from February 1992 and the later publication of V2.1.2 in April 2002.

Which standards are used with SIST EN 300 019-1-5 V2.1.2:2006?

SIST EN 300 019-1-5 V2.1.2:2006 refers to several standards that support class selection and testing.

• IEC 60721-3-5 - provides the environmental class framework for ground vehicle installations.
• IEC 60721-2-1 - defines the climate areas used in Annex A.
• IEC 60068-2-27 - gives shock test guidance and the shock response spectrum reference used for mechanical conditions.
• Part 2 of EN 300 019 - supplies the recommended environmental tests and test severities for the classes defined here.

What does the SIST EN 300 019-1-5 V2.1.2:2006 document contain?

SIST EN 300 019-1-5 V2.1.2:2006 contains six main condition tables covering climatic, biological, chemical, fluid, contamination, and mechanical exposure. It also contains two class descriptions, 5.1 and 5.2, with notes that explain when special classes such as 5C3, 5F2, 5S1, 5M2, and 5M3 may be chosen. For practical work, the tables are used to define the expected service environment before testing, design review, or qualification. Annex A then turns those classes into a climate-area summary for selection.

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 [1].
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 [2].
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-de
