Electro-acoustical measuring equipment for aircraft noise certification.
Specifies requirements for microphone system, tape recorder, filters, attenuators and analyzers. Establishes procedure for data acquisition and calibration and checking of system. This standard should be used in conjunction with ISO 3891.
Comparative information on IEC and North-American flexible cord types.
Contains tables indicating comparative constructions of flexible cords similar to those included in IEC 227 and IEC 245, but which have been used in North America. Provides information for use during the period of time necessary for harmonization to take place from North American types towards the adoption of IEC standards. This information should be of value to those who are concerned with…
Deals with the concept of inherent filtration of X-ray tube assemblies, its definition, methods of indication and its determination, and the statement of inherent filtration measured according to this standard.
Stabilized power supplies, d.c. output - Part 3: Radio-frequency interference tests
Specifies the measuring equipment and techniques to be used in assessing the conducted electromagnetic interference (EMI) generated by stabilized power supplies and especially by switched-mode power supplies. Relates mainly to power supplies for which the source current required does not exceed 25 A. The techniques employed follow the general principles given in CISPR publications. Requirements…
Expression of the properties of cathode-ray oscilloscopes. Part 1: General
Applicable to general-purpose cathode-ray oscilloscopes for measuring electrical quantities. Special definitions. Standard data. Conditions and methods for testing the properties. This publication supersedes IEC 60351 (1971).
Methods of measurement for radio transmitters. Part 6: Cabinet radiation at frequencies between 130 ...
Describes the conditions and methods to measure unwanted radiations originating from sources other than the aerial or aerial system of radio transmitters. The standard is intended to be used in conjunction with IEC 60244-1. The methods of measurement described in this standard are intended for type tests but they may also be used for acceptance tests and factory tests. Does not apply to…
