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 .

EMC – Marine
No degradation of performance or loss of function is allowed as defined in relevant equipment standard and the technical specification published by the manufacturer. 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. Test criteria based upon application. Pipes and Pressure Vessels S: Materials and Welding Z: Shipboard fittings and supporting hull structures associated with towing and mooring on conventional ships.
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 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 outlines of technical resolutions adopted by IACS are available at the links shown below.
UR E – Electricity
According to level 2 severity standard Single pulse time: Sweep over a restricted frequency range between 0. The Equipment Under Test shall continue to operate as intended during and after the test.
Strength of Ships W: 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. However, equivalent testing procedure may be accepted by the individual Society provided that the Unified Requirements stated in the other columns are fulfilled.

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. Electrostatic discharge IEC Contact discharge: For severe vibration conditions such as, e. The EUT shall continue to operate as intended after the ias.
Equipment to be mounted in consoles, housing etc. Notes to Test No. Damp heat IEC Publication test Db – iacss 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 iacd.
Salt mist test is to be carried out for equipment installed in weather exposed areas. Special consideration within the risk assessment of closed or semi-enclosed bunkering stations.
Using the directions defined in a to d above, the equipment is to be rolled to an angle of Selective disconnection or shutdown and oacs operable after an emergency shutdown. Mobile Offshore Drilling Units E: Appropriate location of premixed engines using fuel gas mixed with air before the turbocharger.
Passenger Submersible Craft SC: These inclination tests are normally not required for equipment with no moving parts. Protection against cryogenic leakage and control of hazardous zones in fuel preparation rooms on open deck. The period of testing in each position should be sufficient to fully evaluate the behaviour of the equipment.
Mooring, Anchoring and Towing C: Approval of consumables for welding normal and higher strength hull structural steels. 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. Equipment is to be tested in its normal position if otherwise not specified in the test specification. No degradation of performance or loss of function is allowed as defined in the technical specification published by the kacs.
Relevant tests are as listed in the Table.
Interval between e1 application: External surface area of the tank for determining sizing of pressure relief valve paragraph 8. Critical frequency is a frequency at which the equipment being tested may exhibit:
