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 1-6, deals with ship environments.

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 designed principally for maritime use. Conditions of use vary

significantly in relation to the size of the vessel and the function for which it was designed. The reader

should ensure that the relevant classes are chosen to suit this particular application.

This sub-part covers the following types of vessel:
- vessel propelled by mechanical means, including offshore units;

- vessel not propelled by mechanical means, including sailing boats and life rafts.

The classes defined apply to all sizes of vessel from pleasure craft to trawlers, ferry boats, icebreakers

and cargo ships including tankers.
2 Normative references

This ETS incorporates by dated or undated reference, provisions from other publications. These normative

references are cited at the appropriate places in the text and the publications are listed hereafter. For

dated references, subsequent amendments to, or revisions of any of these publications apply to this ETS

only when incorporated in it by amendment or revision. For undated references the latest edition of the

publication referred to applies.

and terminology".

3 Definitions
In this sub-part of this standard, the following definitions apply:

Totally weatherprotected location: direct weather influences are totally excluded.

Partly weatherprotected 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
4.1 Class 6.1: Totally weatherprotected locations

This class is a combination of classes 6K1/6B1/6C1/6S1/6M3 in IEC publication 721-3-6 [2].

This class applies to equipment installed in totally weatherprotected, heated and ventilated locations

following warm-up on board engine-powered vessels but excluding refrigerated cargo spaces, machinery

spaces and locations containing equipment dissipating considerable amounts of heat. This class does not

cover Warm Damp and Warm Damp Equable climates.

NOTE: Climatic conditions for different areas are defined in IEC publication 721-2-1 [3].

This class applies to:

- equipment which is not exposed to heat radiation from adjacent equipment, heating elements or to

solar radiation through glass or transparent materials;

- installations on board vessels operating in areas without particular risk of attack by flora or fauna. It

also covers other vessels where the installations are located in compartments of such construction

that mould growth and attacks by animals are unlikely;

- totally weatherprotected installations which are not subjected to salt mist, engine exhausts or

emissions from nearby industrial sources;
- installations protected from sand, dust and ingress of soot;
- installations on board engine-powered vessels of all sizes.
4.2 Class 6.2: Partly weatherprotected locations

This class is a combination of classes 6K4/6B2/6C3/6S2/6M3 or 6M4 in IEC publication 721-3-6 [2].

This class applies, depending on the mechanical class chosen, to equipment installed in any location on

board engine-powered vessels - excluding refrigerated cargo spaces. The class applies in all climates with

the exception of Cold climates and areas with abnormal rain intensities and hurricanes. The equipment may

occasionally be subjected to heavy seas. (See the NOTE to subclause 4.1).
This class applies to:

- equipment which is subjected to direct solar radiation, to considerable heat dissipation from boilers,

engines etc., to rain and water jets. The equipment may be connected to wet surfaces;

- non-protected installations on board vessels operating in areas where mould growth and attacks by

animals may occur;

- non-weatherprotected installations on board vessels operating close to industrial areas with

considerable air pollution emissions. Salt mist and exposure to engine exhausts are included;

- all installations where sweeping of dusty decks may take place. It also covers locations subject to

emissions from boiler exhausts (e.g. soot, acid, etc.). Non-weatherprotected installations on board

vessels operating close to sand deserts are not covered;

- class 6M3: installations on board engine-powered vessels of all sizes but excluding equipment

connected directly to reciprocating types of machinery. Equipment connected directly to loading

systems, container guides, cranes and installations in dredgers are included;

- class 6M4: all installations on board engine-powered vessels of all sizes including equipment

connected directly to reciprocating types of machinery.

NOTE: The proper mechanical IEC class 6M3 or 6M4 shall be chosen according to the

expected installations and use of the equipment.
4.3 Class 6.3: Non-weatherprotected locations

This class is a combination of classes 6K5/6B2/6C3/6S2/6M3 or 6M4 in IEC publication 721-3-6 [2].

This class applies, depending on the mechanical class chosen, to equipment installed in any location on

board engine-powered vessels, including refrigerated cargo spaces. This class applies in all climates

including areas with abnormal rain intensities and hurricanes. The equipment may also be subjected to

heavy seas. (See the note to subclause 4.1).
This class applies to:

- equipment which is subjected to direct solar radiation, to considerable heat dissipation from boilers,

engines etc., to abnormal rain, heavy seas and water jets. The equipment may be connected to wet

surfaces;

- non-weatherprotected installations on board vessels operating in areas where mould growth and

attacks by animals may occur;

- non-weatherprotected installations on board vessels operating close to industrial areas with

considerable air pollution emissions. Salt mist and exposure to engine exhausts are included;

- all installations where sweeping of dusty decks may take place. It also covers locations subject to

emissions from boiler exhausts (e.g. soot, acid, etc.). Non-weatherprotected installations on board

vessels operating close to sand deserts are not covered;

- class 6M3: installations on board engine-powered vessels of all sizes but excluding equipment

connected directly to reciprocating types of machinery. Equipment connected directly to loading
