The regulatory requirements in maritime and offshore applications are defined by the standards IEC for maritime navigation and radio communication. Our antennas meet several international standards for marine equipment, such as IEC , GOST, IACS E10 and RMRS. Some of the tests described in the. Dedicated to safe ships and clean seas, IACS makes a unique contribution to maritime safety and regulation through technical support, compliance verification .

Mooring, Anchoring and Towing C: Mobile Offshore Drilling Units E: Special consideration within the risk assessment of closed or semi-enclosed bunkering stations. Texts of the IACS Unified Requirements and Unified Interpretations are made available on this page for the period of one year following the iace of adoption.
Winsonic – IACS-E10
Control and maintenance of pressure and temperature of liquefied gas fuel tanks after the activation of the safety system. 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.
Salt mist test is to be carried out for equipment installed in weather exposed areas. Passenger Submersible Craft SC: Approval of consumables for welding normal and 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 test requirements of test specification items 19 and More severe conditions may exist for example on exhaust manifolds of diesel engines especially for medium and high speed engines.
Appropriate location of premixed engines using fuel gas mixed with air before the turbocharger.
Sweep over a restricted frequency range between 0. Relevant tests are as listed in the Table. No degradation of performance or loss of function is allowed as defined in relevant equipment standard and the technical specification published by the manufacturer.
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.
UR E – Electricity
However, equivalent testing procedure may be accepted by the individual Society provided that the Unified Requirements stated in the other columns are fulfilled. No degradation of performance or loss of function is allowed as defined in the technical specification published by the manufacturer.
Equipment is to be tested in its normal position if otherwise not specified in the test specification. According to level 2 severity standard Single pulse time: For severe vibration conditions such as, e.
The period of testing in each position should be sufficient to fully evaluate the behaviour of the equipment. Electrostatic discharge IEC Contact discharge: Pipes and Pressure Vessels S: Equipment to be mounted in consoles, housing etc.
External surface area of the tank for determining sizing of pressure relief valve paragraph 8. Using the directions defined in a to d above, the equipment is to be rolled to an angle of Protection against cryogenic leakage and control of hazardous zones in fuel preparation rooms on open deck.
The test in each direction is to be carried out for not less than 15 minutes. Recent revisions and changes have been underlined for easy reference.
Damp iacd 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 iace temperature; – recovery at standard atmosphere conditions; – insulation resistance measurements and performance test.
Interval between each application: Notes to Test No. Strength of Ships W: Materials and Welding Z: Critical frequency is a frequency at which the equipment being tested may exhibit: Shipboard fittings and supporting hull structures associated with towing and mooring on conventional ships.
EMC – Marine
The EUT shall continue to operate as intended after the tests. Selective disconnection or shutdown and equipment operable after an emergency shutdown.
Test criteria based upon 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. The Equipment Under Test shall continue to operate iacss intended during and after the test.
