SIST ETS 300 019-1-8 E1:2006 is the Slovenian adoption of ETS 300 019-1-8 Edition 1 from ETSI. It classifies environmental conditions and severities for telecommunications equipment used at underground locations, with a focus on stationary equipment during operation, installation, maintenance, repair, and restoration.
What does SIST ETS 300 019-1-8 E1:2006 specify?
SIST ETS 300 019-1-8 E1:2006 specifies the environmental class for stationary use at underground locations and the severities associated with that class. It is written for places below ground level where equipment is normally protected from direct weather, but may still face humidity, dust, contamination, vibration, shock, and earthquake effects.

| 1 | Scope |
| 2 | Normative references |
| 3 | Definitions and abbreviations |

| 5 | Environmental conditions |
Clause 4 defines Class 8.1: Partly weatherprotected underground locations. Clause 5 then sets out the environmental parameters for climate, biology, chemically active substances, mechanically active substances, mechanical conditions, and earthquake conditions.
What are the key requirements of SIST ETS 300 019-1-8 E1:2006?
SIST ETS 300 019-1-8 E1:2006 gives a single environmental class, but it is detailed enough to guide both site specification and test planning. The main practical point is to match equipment design and verification to the actual underground environment, rather than to a generic indoor or outdoor class.
Class 8.1 and where it applies
Clause 4 says Class 8.1 applies to partly weatherprotected underground locations. In practice, this means places such as footway boxes, manholes, and some tunnels where direct weather is reduced but not eliminated. The class also assumes low-significance vibration and shock, normal urban contamination, and possible short-term immersion in water under exceptional conditions.
Climate and biological exposure
Clause 5.1 lists the climatic parameters for Class 8.1, including temperature range, humidity, air pressure, temperature change, condensation, icing, and exposure to heat radiation. Clause 5.2 covers biological conditions such as mould, fungus, rodents, and other harmful animals, while excluding termites. For users, this means enclosure materials, sealing, ventilation, and internal layout must suit damp, variable underground conditions.
Chemical and particulate exposure
Clause 5.3 gives severities for airborne contaminants such as sea salts, road salts, sulphur dioxide, hydrogen sulphide, chlorine, hydrogen chloride, hydrogen fluoride, ammonia, ozone, and nitrogen oxide. It also notes that the special chemical class 3C3 may be selected for more severe chemical exposure. Clause 5.4 sets levels for sand and dust. In practice, this helps decide corrosion protection, filtering, gasketing, and whether a more severe chemical class is needed near industrial sources.
Mechanical and seismic effects
Clause 5.5 defines stationary vibration and non-stationary vibration including shock, and refers to shock response spectrum types L and II. Clause 5.6 explains seismic conditions using Response Spectrum (RS) and Zero Period Acceleration (ZPA), with values for strong to very strong earthquakes and rigid mounting structures. If the support structure is not rigid, the structure should be included in testing or the RS should be corrected.
What terms does SIST ETS 300 019-1-8 E1:2006 define?
- stationary use - Equipment is permanently placed at a site, with only short handling periods accepted for erection, maintenance, or repair.
- totally weatherprotected location - A location where direct weather influences are fully excluded.
- partly weatherprotected location - A location where direct weather influences are not completely excluded.
- Response Spectrum (RS) - A graph showing the maximum response of single degree-of-freedom oscillators to transient base motion, used to describe seismic motion at the mounting point.
- Zero Period Acceleration (ZPA) - The high-frequency asymptotic value of the response spectrum, representing the largest peak acceleration of the base motion.
Who uses SIST ETS 300 019-1-8 E1:2006?
SIST ETS 300 019-1-8 E1:2006 is used by telecommunications equipment designers, manufacturers, test laboratories, installers, maintenance teams, quality managers, and buyers who need to specify or verify equipment for underground sites. It is relevant where equipment is installed in manholes, footway boxes, tunnels, or similar locations below ground level. It also helps procurement and engineering teams agree on the environmental class before design, testing, or acceptance.
What changed in SIST ETS 300 019-1-8 E1:2006 from the previous edition?
SIST ETS 300 019-1-8 E1:2006 is the first edition of this sub-part as ETS 300 019-1-8. The foreword says it supersedes the application of class 3.2 in ETS 300 019-1-3 for stationary use at underground locations.
Which standards are used with SIST ETS 300 019-1-8 E1:2006?
- ETS 300 019-1-0 - gives the general overview of Part 1.
- ETS 300 019-1-3 - provides the class 3.2 application that this sub-part supersedes for underground locations.
- ETS 300 019-2 - covers the recommended test requirements for the environmental classes.
- IEC Publication 721-3-3: Stationary use at weatherprotected locations - supplies the class combinations referenced for Class 8.1.
- IEC Publication 68-2-27: Test Ea: Shock - supports the shock terminology and the maximax shock reference.
- IEC Publication 721-2-6: Earthquake vibration and shock - defines the seismic environment zone used for Class 8.1.
- IEC Publication 68-3-3: Guidance. Seismic test methods for equipment - supports the RS and ZPA approach and the selection of seismic severities.
What does the SIST ETS 300 019-1-8 E1:2006 document contain?
The document contains a climatogram for Class 8.1, a table of climatic parameters, a table of biological conditions, a table of chemically active substances, a table of mechanically active substances, and a table for vibration and shock conditions. It also includes a section on earthquake conditions that explains RS and ZPA and gives a response spectrum figure with coordinate data. These elements are used for environmental specification, equipment design, and test planning.

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 ETS consists of 2 parts as follows:
Part 1: "Classification of environmental conditions";
Part 2: "Specification of environmental tests".
Part 1 specifies different standardized environmental classes covering climatic and biological conditions,
chemically and mechanically active substances and mechanical conditions during storage, transportation
and in use.
Part 2 specifies the recommended test requirements for the different environmental classes.
Each part of the standard is divided into sub-parts. Sub-part 1-0 forms a general overview of part 1. This
sub-part 1-8, deals with stationary use at underground locations and supersedes the application of
class 3.2 in ETS 300 019-1-3 for such locations.

4 Environmental class
4.1 Class 8.1: Partly weatherprotected underground locations
At present no underground classes in IEC 721 Publication series exist.
This class is a combination of classes 3Z7/3B2/3C2(3C3)/3S3/3M3(3M5) in IEC Publication 721-3-3 [3].
No IEC Publication 721-3-3 [3] climatic class is applicable.
Seismic environment: zone 4 as defined in IEC Publication 721-2-6 [5].
Option zone 4 (modified Mercalli scale ≥ 9): if earthquake conditions are specified by the customer, the
conditions stated in subclause 5.6 apply.
This class applies to partly weatherprotected underground locations. The location has no temperature or
humidity control, but the variations in the temperature are limited due to the stabilizing influence of the
surroundings.
The climatogram is shown in figure 1.
This class applies to locations:
- where the installed equipment is normally protected from direct weather influences;
- where the surrounding medium is normally air, but the equipment may be immersed in water during
exceptional conditions;
- where mould growth or attacks by animals, except termites, may occur;
- with nor
