IEC 60489-6:1987

Refers specially to mobile radio receivers having audio-frequency band-widths generally not exceeding 10kHz for the reception of voice and other types of signals, using: a) angle (Type G or F: phase or frequency) modulation, or b) double-sideband amplitude (Type A) modulation with full carrier, c) or single-sideband amplitude (Type H, J or R) modulation with full, reduced or suppressed carrier. Standardizes the definitions, conditions and methods of measurement used to ascertain the performance of selective-calling receiving-decoders.
