The regulatory requirements in maritime and offshore applications are defined by the standards IEC for maritime navigation and radio communication. IACS Unified Interpretations were created with a view to the uniform The Implementation dates of the Unified Requirements (UR) and Unified Interpretations (UI) are shown in the “Implementation Date” column of the tables.

Critical frequency is a frequency at which the equipment being tested may exhibit: Equipment is to be tested in its normal position if otherwise not specified in the test specification.

UR E – Electricity

The EUT shall continue to operate as intended after the tests. For equipment installed on the bridge and deck zone, the test levels shall be increased to 10V rms for spot frequencies in accordance with IEC at 2, 3, 4, 6.

Strength of S10 W: Shipboard fittings and supporting hull structures associated with towing and mooring on conventional ships. Materials and Welding Z: Texts of the IACS Unified Requirements and Unified Interpretations are made available on this page for the period of one year following the date of adoption. Interval between each application: Mooring, Anchoring and Towing C: Test criteria based upon application.

The outlines of technical resolutions adopted by IACS are available at the links shown below. Notes to Test No. Salt mist test is to be carried out for equipment installed in weather exposed areas. According to level 2 severity standard Single pulse time: Selective disconnection or shutdown and equipment operable after an emergency shutdown. Special consideration within the risk assessment of closed or semi-enclosed bunkering stations.

During the test, degradation or loss of function or performance which is self recoverable is however allowed but no change of actual operating state or stored data is allowed. The Equipment Under Test shall continue to operate as intended during and after the test. No degradation of performance or loss of function is allowed as defined in relevant equipment standard and the technical specification published by the manufacturer.

Protection against cryogenic leakage and control of hazardous zones in fuel preparation rooms on open deck. For severe vibration conditions such as, e. External surface area of the tank for determining sizing of pressure relief valve paragraph 8. Damp heat IEC Publication test Db – measurement of insulation resistance before test; – equipment operating during the complete first cycle and switched off during second cycle except for functional test; – functional test during the first 2 hours of the first cycle at the test temperature and during the last 2 hours of the second cycle at the test temperature; – recovery at standard atmosphere conditions; – iiacs resistance measurements and performance test.

Relevant tests are as listed in the Table. Passenger Submersible Craft SC: Electrostatic discharge IEC Contact discharge: Pipes and Pressure Vessels S: Recent revisions and changes have ru underlined for easy reference. These inclination tests are normally not required for equipment with no moving parts.


The test in each direction is to be carried out for not less than 15 minutes. The period of testing in each position should be sufficient to fully evaluate the behaviour of the equipment. Using the directions defined in a to d above, the equipment is to be rolled to an angle of However, equivalent testing procedure may be accepted by the individual Society provided that the Unified Requirements stated in the other columns are fulfilled. Sweep over a restricted frequency range between 0.

No degradation of performance or loss of function is allowed as defined in the technical specification published by the lacs.

UR E10 Rev6 CLN

Appropriate location of premixed engines using fuel gas mixed with air before the turbocharger. Equipment to be mounted in consoles, housing etc. Approval of consumables for welding normal ias higher strength hull structural steels. Electrical and electronic equipment on board ships, required neither by classification rules nor by International Conventions, liable to cause eletromagnetic disturbance shall be of type which fulfill the ics requirements of test specification items 19 and Mobile Offshore Drilling Units E: Control and maintenance of pressure and temperature of liquefied gas fuel tanks after the activation of the safety system.

More severe conditions may exist for example on exhaust manifolds of diesel engines especially for medium and high speed engines.
