Deals with the determination of performance, the comparison of equipment and the determination of proper practical applications for radio receivers. Does not in general specify performance requirements.

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 parts, 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-broad-casting 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 IEC safety standards, nor with radiation and immunity, for which reference is required to C.I.S.P.R. Publication 13.
