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.

External surface area of the tank for determining sizing of pressure relief valve paragraph 8.

UR E10 Rev6 CLN

The period of testing in each position should be sufficient to fully evaluate the behaviour of the equipment. Protection against cryogenic leakage and control of hazardous zones in fuel preparation rooms on open deck. Mobile Offshore Drilling Units E: 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. Electrostatic discharge IEC Contact discharge: Salt mist test is to be carried out for equipment installed in weather exposed areas.

UR E – Electricity

The Equipment Under Test shall continue to operate as intended during and after the test. 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 test requirements of test specification items 19 and No degradation of performance or loss of function is allowed as defined in relevant equipment standard and the technical specification published by the manufacturer.


Passenger Submersible Craft SC: Sweep over a restricted frequency range between 0.

Interval between each application: Using the directions defined in a to d above, the equipment is to be rolled to an angle of Approval of consumables for welding normal and higher strength hull e01 steels. Equipment is to be tested in its normal position if otherwise not e1 in the test specification. 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; – insulation resistance measurements and performance test.

Strength of Ships W: The test in each direction is to be carried iafs for not less than 15 minutes.

Texts of the IACS Unified Requirements and Unified Interpretations are made available on this page for 1e0 period of one year following the date of adoption. Mooring, Anchoring and Towing C: More severe conditions may exist for example on exhaust manifolds of diesel engines especially for medium and high speed engines.

For severe vibration conditions such as, e.

Selective disconnection or shutdown and equipment operable after an emergency shutdown. According to level 2 severity standard Single pulse time: Pipes and Pressure Vessels S: 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.


Shipboard fittings and supporting hull structures associated with towing and mooring on conventional ships. Control and maintenance of iscs and temperature of liquefied gas fuel tanks after the iscs of the safety system. Critical frequency is a frequency at which the equipment being tested may exhibit: Notes to Test No. Relevant tests are as listed in the Table.

IACS Unified Requirement and Unified Interpretation | ClassNK – English

Appropriate location of premixed engines using fuel gas mixed with air before the turbocharger. Test criteria based upon application. No degradation of performance or loss of function is allowed as defined in iasc technical specification published by the manufacturer. Recent revisions and changes have been underlined for easy reference. Equipment to be mounted in consoles, housing etc. Materials and Welding Z: However, equivalent testing procedure may be accepted by the individual Yr provided that the Unified Requirements stated in the other columns are fulfilled.

The EUT shall continue to operate as intended after the tests. The outlines of technical resolutions adopted by IACS are available at the links shown below. These inclination tests are normally not required for equipment with no moving parts. Special consideration within the risk assessment of closed or semi-enclosed bunkering stations.
