適用范圍：1 This publication applies to the conduction and the radiation of electromagnetic energy from household electrical equipment, portable tools and other electrical apparatus which may cause interference to radio reception, such as: office machines, cine or slide projectors, electric toys, recording apparatus, milking machines, motor-driven electromedical apparatus, etc, but excluding those producing high-frequency radiation for heating and therapeutic purposes.Among portable tools, those with a power in excess of 2 kW are excluded.Separate motors, sold as such, are also excluded.2 The frequency range covered is 0.15 MHz to 300 MHz.3 Multifunction equipment which is subjected simultaneously to different clauses of this publication and/or other publications shall be tested with each function operated in isolation, if this can be achieved without modifying the equipment internally. The equipment thus tested shall be deemed to have complied with the requirements of all the clauses/publications when each function has satisfied the requirements of the relevant clause/publication.For equipment for which it is not practicable to test with each function operated in isolation, or where the isolation of a particular function would result in the equipment being unable to fulfil its primary function, the equipment shall be deemed to have complied only if it meets the provisions of each clause/publication with the necessary functions operative.
