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 .

Interval between each application: Pipes and Pressure Vessels S: The Equipment Under Test shall continue e1 operate as intended during and after the test. Salt mist test is to be carried out for equipment installed in weather exposed areas.
Sweep over a restricted frequency range between 0. For severe vibration conditions such as, e.
Control and maintenance of pressure and temperature of liquefied gas fuel tanks after the aics of the safety system. Equipment to be mounted in consoles, housing etc.
No degradation of performance or loss of function is allowed as defined in the technical specification published by the manufacturer. According to level 2 severity standard Single pulse time: Test criteria based upon application.
iacw 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. 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.
Shipboard fittings and supporting hull structures associated with towing and mooring on conventional ships. Recent revisions and changes have been underlined for easy reference. Special consideration within iiacs risk assessment of closed or semi-enclosed e100 stations. Notes to Test No.
Selective disconnection or shutdown and equipment operable after an emergency shutdown. Relevant tests are as listed in the Table. External surface area of the tank for determining sizing of ixcs relief valve paragraph 8. 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. Appropriate location of premixed engines using fuel gas mixed with air before the turbocharger.
Approval of consumables for welding normal and higher strength hull structural steels.
Electrostatic discharge IEC Contact discharge: 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. Mobile Offshore Drilling Units E: Passenger Submersible Craft SC: 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.
Equipment is to be tested in its normal position if otherwise not specified in the test specification. More severe conditions may exist for example on exhaust manifolds of diesel engines especially for medium and high speed engines. The EUT shall continue to operate as intended after the tests. 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.
The period of testing in each position should be sufficient to fully evaluate the e110 of the equipment. The outlines of technical resolutions adopted by IACS w10 available at the links shown below. Materials and Welding Z: 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. Strength of Ships W: Mooring, Anchoring and Towing C:
