Covers the writing, typing, and printing of dates and times when
all-numeric forms are used, and is applicable for general use. It
is more restrictive than, but is not in conflict with, the
relevant ISO standards. It departs from International Standard

Method for the determination of the proof and the comparative tracking indices of solid insulating m...
Specifies the method of test for the determination of the proof and comparative tracking indices of solid insulating materials on pieces taken from parts of equipment and on plaques of material using alternating voltages. The standard provides for the determination of erosion when required. Test results cannot be used directly for the evaluation of safe creepage distances when designing…
FORMERLY NUMBERED IEC 651
This standard describes instruments (sound level meters) for the measurement of certain frequency and time weighted sound pressure levels.
Tests on indoor and outdoor post insulators of ceramic material or glass for systems with nominal vo...
Applies to post insulators and post insulator units of ceramic material or glass for indoor and outdoor service in electrical installations or equipment operating on alternating current with a nominal voltage greater than 1 000 V and a frequency not greater than 100 Hz.
Notes:
- May also be regarded as a provisional standard for insulators for use on d.c. systems, see IEC 438…
Methods of measurement for radio equipment used in the mobile services - Part 5: Receivers employing...
Deals with the definitions, the conditions and the methods of measurement used to ascertain the performance of receivers having audio-frequency bandwidths generally not exceeding 10 kHz for the reception of voice and other types of signals, using single-sideband amplitude modulation. The standard is intended to be used in conjunction with IEC 489-1.
Methods of measurement for radio equipment used in the mobile services - Part 3: Receivers for A3E o...
Deals with the definitions, the conditions and the methods of measurement used to ascertain the performance of receivers having audio-frequency bandwidths generally not exceeding 10 kHz for the reception of voice and other types of signals, using angle modulation (phase/frequency modulation), or
double-sideband amplitude modulation with full carrier. This standard is intended to be used in…
Guide for determining the effects of ionizing radiation on insulating materials - Part 2: Procedures...
Specifies the controls which shall be maintained over the exposure conditions during and following the irradiation of insulating materials with ionizing radiation prior to the determination of radiation-induced changes in physical or chemical properties. A number of potentially significant irradiation conditions are discussed and various parameters which can influence the radiation-induced…
