適用范圍：1.1 This Malaysian Standard specifies limits and methods of measurement for the electromagnetic interference which is generated by the electrical and electronic equipment of a marine installation. The standard applies only to interference which is generated in the ship.1.2 Limits in the frequency range 15 kHz to 100 MHz are specified for:(a) the radio frequency voltage or current appearing at the power supply terminals of the electrical and electronic equipment;(b) the radio frequency voltage appearing in the aerial feeder.1.3 The limits cover the frequency range 15 kHz to 100 MHz and relate to measurements made by equipment complying with the requirements of section one of BS 727 : 1967.1.4 Guidance on measures which may have to be applied in order to achieve compliance with the specified limits is provided in the Code of Practice BS 5260.1.5 Requirements and tests are specified for components used for the suppression of interference, whose failure could seriously endanger the safety of a ship either by;(a) interference as the result of component failure, which would disorganize radio equipment (or electronic systems) on board; or by(b) component failure which could upset or stop the operation of vital electrical equipment (e.g. steering motors or navigational aids) to which the component is fitted.The components specified are intended for use withelectrical devices on board ship rated up to 500 V dc or 500 V ac between conductors, or 250 V dc or 290 V ac between one conductor and earth at frequencies not exceeding 400 Hz.NOTE 1. It is essential for all suppression components which may be used as above to be of high quality. In this connection the component manufacturer's experience should be taken into consideration because proof of operational reliability cannot be completely furnished by short term testsNOTE 2. Interference suppression components for shipboard use which do not fall into either of the categories (a) or (b) should meet the conditions specified in BS 613 : 1967.
