The International Association of Classification Societie's IACS is a technically based non-governmental organization that currently consists of twelve member marine classification societies. Marine classification is a system for promoting the safety of life, property and the environment primarily through the establishment and verification of compliance with technical and engineering standards for the design, construction and life-cycle maintenance of ships, offshore units and other marine-related facilities. These standards are contained in rules established by each Society. IACS provides a forum within which the member societies can discuss, research and adopt technical criteria that enhance maritime safety. The convention recommended collaboration between classification societies to secure "as much uniformity as possible in the application of the standards of strength upon which freeboard is based A second major class society conference, held in , led to the creation of working parties on specific topics and, in , to the formation of IACS by seven leading societies.

E10 A2. Test Specification for Type Approval. This Test Specification is applicable, but not confined, to electrical, electronic and. July May These tests are to demonstrate the ability of the equipment to function as intended under the. The extent of the testing i. Dec Oct Equipment is to be tested in its normal position if otherwise not specified in the test.

Equipment intended to be installed on ships contracted for construction on or after 1 January is to comply with Rev. Page 1 of IACS Req. Relevant tests are as listed in the Table. Electrical and electronic equipment on board ships, required neither by classification rules nor by International Conventions, liable to cause electromagnetic disturbance shall be of type which fulfil the test requirements of test specification items 19 and As used in this document, and in contrast to a complete performance test, a functional test is a simplified test sufficient to verify that the equipment under test EUT has not suffered any deterioration c aused by the individual environmental tests.

Type testing condition for equipment covered by E However, equivalent testing pr ocedure may be accepted by the individual Society provided that the Unified Requirements stated in the other col umns are fulfilled. The latest edition of the no rmative reference applies. Visual inspection. Performance test. Manufac turer performance test programme based upon specification and relevant Rule requirements.

When the EUT is required to comply with an international performance standard, e. Page 2 of External power supply failure. The time of 5 minut es may be exceeded if the equipment under te st needs a longer time for start-up, e.

Power supply variations. For equipment which re quires booting, one additional power supply interruption during booting to be performed Verification of:. Voltage tolerance. Voltage cyclic. Voltage ripple. Electric battery supply:.

For severe vibration conditions such as, e. Page 4 of Sweep over a restricted frequency range between 0. Note: Critical frequency is a frequency at which the equipment being tested may exhibit:. More severe conditions may exist for example on exhaust manifolds or fuel oil injection systems of diesel engines.

For equipment specified for increased vibration levels the vi bration test is to be conducted at the agreed vibration level, frequency range and duration. IEC Static Note: The period of testing in each posi tion should be sufficient to fully eval uate the behav iour of the equipment. Dynamic Using the directions defined in a to d above, the equipment is to be rolled to an angle of The test in each direction is to be carried out for not less than 15 minutes.

Note: These inclination tests are normally not required for equipment with no moving parts. Page 5 of Insulation resistance. High voltage. Salt mist. Rated voltage. Up to Test voltage A. IEC Test Kb. Four spraying periods with a storage of 7 days after each. Note: Certain components e. Page 6 of Electrostatic discharge. Electromagnetic field. Frequency range:. Conducted low.

Page 10 of Salt mist test is to be carried out for equipment installed in weather exposed areas. No degradation of performance or loss of function is allowed as defined in the technical specification published by the manufacturer. 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.

Performance Criterion A: For continuous phenomena : The Equipment Under Test shall continue to operate as intended during and after the test. No degradation of performance or loss of function is allowed as defined in relevant equipment standard and the technical specification published by the manufacturer.

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. Power supply. End of. P age 11 of
