Methods of measurement for radio equipment used in the mobile services - Part 4: Transmitters employ...
Covers the definitions, the conditions and the methods of measurement used to ascertain the performance of transmitters having audio-frequency bandwidths generally not exceeding 10 kHz for the transmission of voice and other types of signals, using single-sideband amplitude modulation with full, reduced or suppressed carrier. This standard is intended to be used in conjunction with IEC 489-1.
Rotating electrical machines - Part 12: Starting performance of single-speed three-phase cage induct...
Specifies four standard designs of starting performance for three-phase motors, from 0.4 kW up to 630 kW for direct on-line or star-delta starting and rated on the basis of duty-type S-1 (maximum continuous rating). Also covers dual voltage motors in so far as the flux saturation level is the same for both voltages.
Standard method of measuring the pinch temperature of quartz-tungsten-halogen lamps
Specifies details of the type of thermocouple to be used to measure the pinch temperature of quartz-tungsten-halogen lamps, the methods of preparation of the lamp and thermocouple, and the measurement to be made.
