Over deze norm
||Geluid, beeld en multimedia-apparaten en -systemen
Describes methods of measurement and special test signals for the analogue audio part of equipment mainly dedicated to recording reproduction of TV signals on magnatic tape on reels or in cassettes. The allowable tolerances for the related values for acceptable performance are not given in this standard, but may be derived from the specifications for the related system i.e. appropriate publications, manufacturers specification etc. The necessary reference and calibration tapes are neither mentioned in the specific IEC publication of the equipment under test or included in IEC 61105 and IEC 61295, respectively. The methods are applicable to acceptance tests, performance comparison and, as far as possible, to routine checks.
