Applies to pre-recorded optical reflective videodisks compatible with 50 Hz-625 lines CCIR monochrome and colour coding PAL systems, and defines those parameters that effect the interchangeability of the disk, excluding limitations of the programming material and source. Serves as a reference for manufacturers intending to make disks or players compatible with the optical system described. See…

Defines parameters and outlines test methods for measuring performance of pulse-echo medical diagnostic systems that employ single-element transducers and operate in the 0.5 MHz to 25 MHz acoustic frequency range. Provides a generally acceptable basis for measuring and reporting the principal performance parameters of complete diagnostic systems. The performance parameters specified, and the…

The methods of measurement detail the techniques and procedures for use when measuring fields on site near to an overhead line and also the techniques and procedures for making laboratory measurements of interference voltages and currents generated by line equipment and accessories. The procedures for determining limits define the expected values of radio noise field and the width of the "…

Specifies the methods of measuring magnetic, properties of isotropic nickel-iron soft magnetic alloys, types El, E3 and E4, as defined in IEC 60404-1.

For application in equipment containing semiconductor devices for circuits up to 1000 V a.c. to circuits of nominal voltages up to 1500 V d.c. Establishes characteristics of semiconductor fuse-links in such a way that they can be replaced by other fuse-links having the same characteristics provided their dimensions are identical. Defines standard conditions for operation in service,…

Specifies the general operating characteristics and standardization principles. Does not define a specific pattern for the connection system from the point of view of dimensions, but lays down limits for the design and performance for each system. This part lays down the basic requirements for the mechanical structure and electrical performances as well as the basic environmental conditions in…

Covers both the male end dimensions, and the female end dimensions. The pitch p/ps as given in the tables defines the spline dimensions. The first number is the diametral pitch; the second number is the stub pitch; it denotes, as the fractional part of an inch, the basic radial length of engagement, both above and below the pitch circle. The module denotes the number of units of pitch diameter…

Defines the procedures for determining the exterior A-weighted equivalent continuous sound power level, A-weighted exterior sound pressure levels, and operator A-weighted sound pressure levels emitted by construction, forestry, and mining machinery with net engine power greater than 15 kW. The categories of machinery covered by this Standard are tractor, loader, dumper, tractor-scraper,…

Applies to non-perforated magnetic tape used for professional and domestic analogue sound recording and reproduction. Lists and defines the methods of measurement and equipment necessary to determine the mechanical characteristics of magnetic recording tape. Will also enable users of magnetic tapes to compare technical product data of different manufacturers, produced in accordance with this…

Applies to electronic indirect a.c. convertor systems with electrical energy storage means in the d.c. link. Defines a complete uninterruptible power system in terms of its performance and not in terms of individual sub-system functional units.
