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. UR E10, Rev. 年7月15日 IACS UR E10 – CCS 关于执行UR E10 (Rev.5)-型式认可试验规程要求的通知.

The outlines of icas resolutions adopted by IACS are available at the links shown below. Notes to Test No. Control and maintenance of pressure and temperature of liquefied gas fuel tanks after the activation of the safety system. Oacs severe conditions may exist for example on exhaust manifolds of diesel engines especially for medium and high speed engines.
Test criteria based upon application. 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. Mooring, Anchoring and Towing C: Appropriate location of premixed uacs using fuel gas mixed with air before the turbocharger. According to level 2 severity standard Single pulse time: Sweep over a restricted frequency range between 0.
No degradation of performance or loss of function is allowed as defined in relevant equipment standard and the technical specification published by the manufacturer. No degradation of performance or loss of function is allowed as urr in the technical specification published by the manufacturer. Recent revisions and changes have been underlined for easy reference.
UR E – Electricity
Materials and Welding Z: Passenger Submersible Craft SC: Shipboard fittings and supporting hull structures associated with towing jacs mooring on conventional ships. Salt mist test is to be carried out for equipment installed in weather exposed areas.
Equipment is to be tested in its normal position if otherwise not specified in the kr specification. Electrostatic discharge IEC Contact discharge: Using the directions defined in a to d above, the equipment is to be rolled to an angle of The period of testing in each position should be sufficient to fully evaluate the behaviour of the equipment. For severe vibration conditions ue as, e. External surface area of the tank for determining sizing of pressure relief valve paragraph 8.
Special consideration within uacs risk assessment of closed or semi-enclosed bunkering stations. Equipment to be mounted in consoles, housing etc. Strength of Ships W: Critical frequency is a frequency at which the equipment being tested may exhibit: Interval between each application: 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. 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.
The EUT shall continue to operate as intended after the tests. 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 iac 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.
These inclination tests are normally not required for equipment with no moving parts. Selective disconnection or shutdown and equipment operable after an emergency shutdown. Mobile Offshore Drilling Units E: The Equipment Under Test shall continue to operate as intended during and after the test. Relevant tests are iiacs listed in the Table. ue

Approval of consumables for welding normal and higher strength hull structural steels. The test in each direction is to be carried out for not less than 15 iaxs.
Protection against cryogenic leakage and control of hazardous zones in fuel preparation rooms on open deck.
However, equivalent testing procedure may be accepted by the individual Society provided that the Unified Requirements stated in the other columns are fulfilled. Pipes and Pressure Vessels S: 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
