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 will specify 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 1-7, deals with portable and non-stationary use.
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".

1 Scope
The purpose of this sub-part of this standard is to define the classes 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%.
This sub-part applies to equipment during portable and non-stationary use including periods of transfer,
down time, maintenance and repair.

and terminology".

3 Definitions
Portable and non-stationary use: the equipment may be moved frequently from place to place. The total
transfer time may amount to a significant portion of the equipment's lifetime. The equipment is not
permanently mounted on any structure or placed at a fixed site. The equipment may be operating while
being either in a stationary or in a transfer state.
Weatherprotected location: a location at which the equipment is protected from direct weather
influences.
Totally weatherprotected location: (enclosed location) direct weather influences are totally excluded.
Partly weatherprotected: location (sheltered location) direct weather influences are not completely
excluded.
Non-weatherprotected location: a location at which the equipment is not protected from direct weather
influences.
4 Environmental classes
Two mechanical classes, 7M2 and 7M3, are used and cover all the environmental classes 7.1 to 7.3 E.
The relevant class is determined by consideration of the expected handling, means of transfer and
complete use-profile of the equipment.
The special, severe, class 7M3 applies to use only in circumstances where the equipment is exposed to
rough handling, severe shocks and vibration e.g. from the means of transfer or rotating machinery.
The severities shown in parentheses, e.g. (7C1), may be selected for special applications.

4.1 Class 7.1: Temperature controlled locations
This class is a combination of classes 7K1/7Z2/7Z4/7B1/7C2(7C1)/7S1/7M2 or 7M3 in IEC publication
721-3-7 [2].
This class applies to use at, and direct transfer between, permanently temperature-controlled and
enclosed locations. Humidity is usually not controlled. The climatogram is shown in figure 1.
Heating, cooling or humidification is used, where necessary, to maintain the required conditions, especially
where there is a large difference between the internal climate and that open-air climate. Heating or cooling
may be switched off for periods but the occurrence of extremely high or low temperatures is prevented.
This class applies to use at, and transfer between, locations:
- where the equipment may be exposed to solar radiation and to heat radiation. It may also be
exposed to movements of the surrounding air (e.g. due to draughts in buildings through open
windows) and to condensed water. It is not subjected to precipitation, or water from sources other
than rain or icing;
- without particular risk of biological attack. This includes protective measures, e.g. special product
design, or installation in locations of such construction that mould growth and attacks by animals,
etc. are not probable;
- with normal levels of contaminants experienced in urban areas, with industrial activities scattered
over the whole area and/or with heavy traffic;
- without special precautions to minimise the presence of sand or dust, but which are not situated in
proximity to sources of sand or dust.
The mechanical class shall be determined by reference to Clause 4, "Environmental classes".
The conditions of this class may be found in, and during transfer to, normal living or working areas, e.g.:
- living rooms;
- rooms for general use (theatres, restaurants, etc.);
- offices;
- shops;
- workshops;
- telecommunication centres;
- storage rooms for valuable and sensitive products.

4.2 Class 7.2: Partly temperature-controlled locations
This class is a combination of classes 7K2/7Z2/7Z4/7Z9/7B2/7C2(7C1)/7S2/7M2 or 7M3 in IEC
publication 721-3-7 [2].
This class applies to use at, and direct transfer between, enclosed locations having neither temperature
nor humidity control. The climatogram is shown in figure 2.
Heating may be used to raise low temperatures especially where there is a large difference between the
conditions of this class and the open-air climate. Building construction is designed to avoid extremely high
temperatures.

This class applies to use at, and direct transfer between, locations:
- where equipment may be exposed to solar radiation and heat radiation. It may also be exposed to
movements of the surrounding air (e.g. due to draughts in buildings through open windows). It may
be subjected to condensed water, to water from sources other than rain and to icing. It is not
subjected to precipitation;
- where mould growth, or attacks by animals except 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;
- in close proximity to sources of sand or dust.
The mechanical class shall be determined by reference to Clause 4, "Environmental classes".
The conditions of this class may be found in, and during transfer to:
- entrances and staircases of buildings;
- in garages;
- cellars;
- certain workshops;
- buildings in factories and industrial process plants;
- unattended equipment stations;
- certain telecommunication buildings;
- ordinary storage rooms for frost resistant products;
- farm buildings etc.
NOTE 2: Underground spaces and manholes, etc.: Class 7.2 can be used in these locations
although the distribution and duration of severities are different. The relative humidity
exceeds 95 % RH for more than 1 % of the time and may reach 100 %.

4.3 Class 7.3: Partly weatherprotected and non-weatherprotected locations
This class is a combination of classes 7K3/7Z2/7Z6/7Z9/7B2/7C2/7S2/7M2 or 7M3 in IEC publication 721-
3-7 [2].
This class applies to use at partly weatherprotected locations in buildings of such a construction that
extremely low temperatures are avoided. This class also applies to use at non-weatherprotected locations
in a Warm Temperate climate and to transfer between these locations. During cold seasons non-
weatherprotected use and transfer is limited). The climatogram is shown in figure 3.
Climatic conditions for different areas are defined in IEC public
