This part of IEC 61305 applies to household high-fidelity radio tuner units with facilities for reception of frequency modulation sound broadcasts with a rated maximum system deviation of ±75 kHz, using the pilot-tone system for stereophonic broadcasting (see ITU-R BS.450-2). It may be applied to systems using a rated maximum system deviation of ±50 kHz by decreasing all the stated deviations in proportion. It also applies, except where stated, to equipment having multiple functions, including these facilities. It is intended to be read in conjunction with part 1 of this standard.

This standard applies to radio receivers of any kind, excluding television receivers, and to the parts of which they are composed or which are used as auxiliaries to such receivers, excluding those dealt with in IEC Publications 94, 98 and 268. This standard deals with the determination of performance, the comparison of equipment and the determination of proper practical applications by listing the characteristics which are useful for specifications and laying down uniform methods of measurement for these characteristics. This standard is confined to a description of the different characteristics and the relevant methods of measurement; it does not in general specify performance requirements. The complete standard consists of the following pa rts, in which the characteristics of various types of receiver and their methods of measurement are specified; some parts include preferred Values: — Part 1: General considerations and methods of measurement, including audio-frequency measurements (IEC Publication 315-1 (1988)). — Part 3: Radio-frequency measurements on receivers for amplitude-modulated emissions (Publication 315-3 (1973)). — Part 4: Radio-frequency measurements on receivers for frequency modulated sound-broadcasting emissions (Publication 315-4 (1982)). — Part 5: Specialized radio-frequency measurements. Measurements on frequency-modulated receivers of the response to impulsive interference (Publication 315-5 (1971)). — Part 8: Radio-frequency measurements on professional receivers for frequency-modulated telegraphy systems (Publication 315-8 (1975)). The standard does not deal with safety, for which reference is required to IEC Publication 65 or other appropriate I EC safety standards, nor with radiation and immunity, for which reference is required to C.I.S:P.R. Publication 13.

This standard applies to radio receivers for the reception of amplitude-modulated sound broadcasting emissions. It deals mainly with measurements using radio-frequency signals applied to the antenna terminals of the receiver, or induced in a magnetic antenna. This part is intended to be read in conjunction with Part 1 (IEC 60315-1, Second edition). Immunity is not covered, except for an explanation with cross-reference to CISPR publications. For radiation from receivers, reference is required to CISPR Publication 13. NOTE 1 – Receivers without volume controls or a.f. power output stages (\"tuners\") are included. NOTE 2 – Receivers for single-sideband and independent-sideband emissions are not included, nor are receivers for stereophonic emissions as far as characteristics involving the encoding system are concerned

This part of IEC 60315 applies to radio receivers and tuners for the reception of frequency modulated sound-broadcasting emissions with rated maximum system deviations of ±75 kHz and ±50 kHz in ITU Band 8. It deals mainly with methods of measurement using radiofrequency signals applied to the antenna terminals of the receiver. The measurements and specified conditions of test are selected to permit the comparison of results obtained by different observers and on other receivers. Performance requirements are not specified in this standard. Radiation and immunity tests and requirements are not included since these are described in CISPR 13 and CISPR 20
