Characteristics of string insulator units of the long rod type
Prescribes specified values for the electrical and mechanical characteristics and for the principal dimensions of string insulator units of the long rod type with insulating parts of ceramic material intended for a.c. overhead lines with a nominal voltage greater than 1 000 V and a frequency not greater than 100 Hz. The smallest insulator unit standardized has a lighting impulse withstand voltage…
Methods for measuring the performance of electric household coffee makers
States and defines the principal performance characteristics for electric coffee makers, which are of interest to the user and describes the standard methods for measuring these characteristics.
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.
Packaging of components for automatic handling. Part 1: Tape packaging of components with axial lead...
Standardizes the methods, general dimensions and preferred tolerances for the taping of these components, for example, resistors, capacitors, diodes, etc., for use in telecommunication equipment and electronic devices employing similar assembly techniques.
Printed boards - Part 4: Specification for single and double sided printed boards with plain holes
Defines the characteristics to be assessed, the test methods to be used and establishes uniform requirements for judging properties and dimensions of single and double sided printed boards with plain holes. This standard is intended as a basis on which agreements between purchaser and vendor can be made.
Recommended methods of measurement on receivers for television broadcast transmissions. Part 2: Elec...
Applies to broadcast television receivers designed for monochrome and colour vision reception with accompanying sound. The standard constitutes a catalogue of selected measurements recommended for assessing electrical and acoustic properties of receivers such as audio-frequency response characteristic, volume control characteristic, audio-frequency non-linearity distortion, internally generated…
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.
