SIST EN 300 019-1-6 V2.1.2:2006 is a Slovenian standard published by SIST and identical to EN 300 019-1-6 Version 2.1.2. It classifies environmental conditions and severities for telecommunications equipment in ship environments, so designers, test labs, quality managers and buyers can match equipment to maritime operating conditions.

What does SIST EN 300 019-1-6 V2.1.2:2006 specify?

SIST EN 300 019-1-6 V2.1.2:2006 defines environmental classes for telecommunications equipment intended principally for maritime use. It tells the reader which shipboard locations and exposure levels belong to each class, so the right class can be selected before design, testing or procurement.

The scope covers vessels propelled by mechanical means, including offshore units, and vessels not propelled by mechanical means, including sailing boats and life rafts. The classes apply across vessel sizes from pleasure craft to trawlers, ferry boats, icebreakers and cargo ships including tankers.

The document is organized into:

• Clause 1 Scope
• Clause 2 References
• Clause 3 Definitions
• Clause 4 Environmental classes
• Clause 5 Environmental conditions
• Annex A Bibliography

The foreword also places this part in the wider ETSI EN 300 019 series. Part 1 covers classification of environmental conditions, Part 1-0 is the general overview, and Part 2 gives the recommended environmental test severities and test methods.

What are the key requirements of SIST EN 300 019-1-6 V2.1.2:2006?

SIST EN 300 019-1-6 V2.1.2:2006 is mainly a classification document. Its practical value is that it links a shipboard location and exposure profile to a defined environmental class, which can then be used for equipment specification and qualification.

Environmental classes in Clause 4

Clause 4 defines three environmental classes:

• 6.1 for totally weatherprotected locations
• 6.2 for partly weatherprotected locations
• 6.3 for non-weatherprotected locations

Each class is a combination of climatic, biological, chemically active, mechanically active and mechanical conditions from IEC 60721-3-6. In practice, the class choice determines how exposed the equipment is expected to be on the vessel.

Class 6.1 applies to heated and ventilated, totally weatherprotected locations on engine-powered vessels, with exclusions such as refrigerated cargo spaces, machinery spaces and places with major heat dissipation. It also assumes protection from direct solar radiation through glass, salt mist, exhaust emissions, sand, dust and soot. This is the least severe of the three ship classes.

Class 6.2 applies to partly weatherprotected locations on engine-powered vessels, excluding refrigerated cargo spaces. It covers locations with direct solar radiation, rain, water jets, wet surfaces, pollution, salt mist and engine exhausts, and it allows occasional heavy seas. The document says the proper mechanical class, 6M3 or 6M4, shall be chosen according to installation and use.

Class 6.3 applies to non-weatherprotected locations on engine-powered vessels, including refrigerated cargo spaces. It extends the exposure to abnormal rain intensities and hurricanes, together with heavy seas. This is the most severe shipboard class in the document.

Environmental conditions in Clause 5

Clause 5 gives the severities for the classes in five groups:

• climatic conditions
• biological conditions
• chemically active substances
• mechanically active substances
• mechanical conditions

For climate, the tables set the expected severities for temperature, humidity, air movement, precipitation, solar radiation, heat radiation, spray or other water exposure, and wetness. For a reader, this means the environment can be translated into test and design assumptions instead of being described only in general terms.

For biological conditions, the document distinguishes negligible flora and fauna in 6.1 from mould, fungus, rodents and other harmful animals in 6.2 and 6.3. That matters when deciding enclosure sealing, materials and maintenance planning.

For chemically active substances, the document covers salts and several airborne gases, and it includes sea salts in water for the harsher ship classes. It also notes that tanker cargo-related substances may require IEC 60092-502.

For mechanically active substances, the document covers sand in air, dust sedimentation and soot deposit. For equipment in machinery spaces, the note on oil droplets is relevant because contamination can affect cooling, contacts and moving parts.

For mechanical conditions, the document uses the classes 6M3 and 6M4. These cover vibration, shock, angular deviation, angular motion and steady-state acceleration, and the notes explain how the vessel axes are defined. This is the part used when equipment must survive mounting orientation, vibration from engines and shock from ship motion.

What terms does SIST EN 300 019-1-6 V2.1.2:2006 define?

• Absolute humidity - the mass of water vapour associated with one cubic metre of dry air in an air/water vapour mixture.
• Relative humidity - the ratio of water vapour partial pressure in moist air to the saturation value at the same temperature.
• Non-weatherprotected location - a location where the equipment is not protected from direct weather influences.
• Totally weatherprotected location - a location where direct weather influences are totally excluded.
• Partly weatherprotected location - a location where direct weather influences are not completely excluded.
• 6M3 / 6M4 - the mechanical classes used for shipboard installations, with 6M4 the more inclusive choice for equipment directly connected to reciprocating machinery.

Who uses SIST EN 300 019-1-6 V2.1.2:2006?

SIST EN 300 019-1-6 V2.1.2:2006 is used by telecommunications equipment designers, test laboratories, marine system integrators, quality managers and buyers. They use it when selecting the environmental class for equipment installed on ships, when setting test severities, and when documenting the expected maritime operating environment.

It is especially relevant for equipment intended for engine-powered vessels, offshore units, sailing boats, life rafts and other shipboard installations where exposure depends on location and vessel type.

What changed in SIST EN 300 019-1-6 V2.1.2:2006 from the previous edition?

The document history identifies earlier publication as ETS 300 019-1-6 edition 1 and later publication as V2.1.2. The history also records a V2.1.0 approval cycle before this publication.

Which standards are used with SIST EN 300 019-1-6 V2.1.2:2006?

Clause 2 names these references:

• IEC 60721-3-6 - supplies the environmental class framework that this part combines into 6.1, 6.2 and 6.3.
• IEC 60721-2-1 - provides climatic condition background used for warm and cold climate notes.
• IEC 60068-2-27 - gives shock test terminology and guidance for the shock-related notes.
• IEC 60092-502 - is referenced for tanker-specific circumstances and cargo-related severity concerns.
• ISO 2041 - provides vibration and shock vocabulary used in the mechanical notes.

The foreword also points to the companion parts in the ETSI EN 300 019 series: Part 1-0 for the overview and Part 2 for test severities and methods.

What does the SIST EN 300 019-1-6 V2.1.2:2006 document contain?

SIST EN 300 019-1-6 V2.1.2:2006 contains a class structure and five condition tables rather than a test procedure of its own. The tables cover climate, biological exposure, chemically active substances, mechanically active substances and mechanical conditions for ship environments.

It also includes notes that explain how to choose between classes, especially the difference between weatherprotected and non-weatherprotected locations and between 6M3 and 6M4. Annex A is an informative bibliography.
