Non-ionizing radiation hazards in the frequency range from 10 MHz to 300 000 MHz
Summarizes the present position on difference in limits and attitudes towards non-ionizing hazards adopted by a number of different countries, and by the IEC and other international organizations, in standards and recommendations. Has the status of a technical report.
Deals with sound level meters of four degrees of precision, designated Types 0, 1, 2 and 3. Specifies the following characteristics: directional characteristics, frequency weighting characteristics, time-weighting, detector and indicator characteristics, sensitivity to various environments. Establishes electrical and acoustical tests to verify compliance with characteristics specified and…
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…
Values for the difference between free-field and pressure sensitivity levels for one-inch standard c...
Gives the values that are to be added to the pressure sensitivity level of a microphone in order to obtain the free-field sensitivity level when a very high accuracy is not called for or when conditions for carrying out an accurate free-field calibration are not available.
The values given have been derived from measurements of the pressure and free-field sensitivity levels of a number of…
Contains an 'experimental' standard defining an ultrasonic cleaning exposure test designed to determine the ability of components and equipment to withstand the effects of ultrasonic cleaning. Has the status of a technical report.
