Marine Testing — What Does This Testing Field Cover?
The section below describes how the field of Marine Testing works. The conditions, sample requirements and acceptance criteria of the individual tests in this field are given on the relevant test pages.
Marine testing shows that equipment used on board withstands the marine environment and shipboard operating conditions. The character of the environment is decisive: continuous salt-laden humidity, rolling and pitching, engine-borne vibration, limited opportunity for maintenance and the difficulty of evacuation in the event of a failure.
The most distinctive aspect of the field is the CONSEQUENCE OF FAILURE. A device that fails ashore is replaced; a navigation device that fails at sea means the ship does not know its position. Durability expectations and the certification burden for marine equipment are therefore markedly higher than for comparable equipment ashore.
Navigation and communication equipment is assessed under IEC 60945; this standard carries environmental durability, EMC and functional requirements together and distinguishes categories according to where the equipment will be mounted on board: protected, exposed deck and submerged categories are subject to different requirements.
On the digital interface side the IEC 61162 series is used. This is the body of protocols enabling devices on the bridge to talk to one another; in integrated bridge systems it must be shown that data exchange between devices works correctly.
On the shipboard electrical installation side the IEC 60092 series applies: cable types, installation rules, protection coordination and fire behaviour. Flame spread and halogen-free construction carry particular weight for cables on board, because smoke in an enclosed space directly obstructs evacuation.
On the shock side, naval vessels carry their own regime: the MIL-S-901 high-impact shock test simulates the effect of an underwater explosion. Testing at this scale is not required for civil ships, but vibration and inclination/roll tests are standard.
On the regulatory side the Marine Equipment Directive (MED) is decisive: equipment within scope carries the "wheelmark" and this is a regime SEPARATE from CE. Behind the requirements stand the SOLAS convention and International Maritime Organization resolutions; the scope list is updated regularly.
Classification societies add a second layer. DNV, Lloyd's Register, ABS, Bureau Veritas and similar bodies issue their own type approvals; a shipyard usually requires both the wheelmark and the relevant class approval. The two processes do not substitute for one another.
Method groups in this field
Environmental durability
Temperature, humidity, salt fog, vibration, rain and immersion under IEC 60945; levels according to the mounting category.
Electromagnetic compatibility
The EMC sections of IEC 60945; emission and immunity requirements specific to the shipboard environment.
Mechanical
Vibration, shock, inclination and roll tests; MIL-S-901 high-impact shock for naval vessels.
Electrical installation
Cable and installation requirements under the IEC 60092 series; cable fire behaviour and halogen-free construction.
Digital interface
Data interface conformity under the IEC 61162 series and integrated bridge system compatibility.
Fire safety
Reaction to fire, smoke and toxicity for shipboard interior materials; fire resistance for hoses and penetrations.
Commonly confused in this field
- The wheelmark is not the CE marking; it is a different regulatory regime with its own scope list.
- MED approval and classification society type approval do not substitute for one another; a shipyard usually requires both.
- The IEC 60945 category selection depends on the mounting location; an approval obtained for a protected area is not valid for an exposed deck.
- An approval obtained for a civil ship does not satisfy naval shock requirements.
- An onshore EMC report is not sufficient for marine use; IEC 60945 defines its own limits and set-ups.
- Scope lists are updated; equipment once outside the scope may later fall within it.
Which decisions these results support
- Marine equipment type approval and the wheelmark
- Classification society type approval
- Compliance with shipbuilding and shipyard procurement specifications
- Shock qualification in naval programmes
- Verification of integrated bridge system compatibility
