Applies to single and double sided printed boards with through connections irrespective of their method of manufacture. Is intended as a basis on which agreements between purchaser and vendor can be made. Defines the characteristics to be assessed, the test methods to be used and establishes uniform requirements for judging properties and dimensions.
Expression of the properties of spectrum analyzers
Applies to non-real time analyzers which perform an analysis of the power distributor of a signal by a sampling process. Defines the terminology; lays down uniform methods of expression of the properties of analyzers; specifies the conditions and methods for testing properties of apparatus.
Testing of semiconductor valves for high-voltage d.c. power transmission
Defines terms of insulation co-ordination and valve construction. Describes methods for type tests carried out to verify that the valve design will meet the specified requirements. Covers production tests carried out to verify proper manufacture. Production tests consist of routine tests (on all valves, modules or components) and sample tests (on a small number taken at random from a batch).…
Methods of measurement for equipment used in terrestrial radio-relay systems. Part 2-1: Measurements...
Defines measurement methods for assessing the electrical characteristics of sub-systems in order to facilitate the comparison of results of measurements made by different observers. The methods described are intended for 'type' and 'acceptance' tests and they may also be used for factory tests.
Presents a set of software subroutines to provide a general capability for communications with CAMAC systems as defined in IEC 60516. The subroutines are suitable for use with Fortran although they are not restricted to that language.
Requirements for the Shutdown Systems of CANDU Nuclear Power Plants
1. Scope
1.1 This Standard is primarily concerned with the nuclear safety of Shutdown Systems, i.e., their ability to terminate the nuclear reaction during a potentially hazardous situation. However, it recognizes that the repeated unnecessary operation of a Shutdown System will needlessly stress the nuclear plant and, possibly, lead to earlier system and component failures. Therefore, this…
Defines the main terms (given in English, French, and Russian) relating to those phenomena leading to uncontrolled engine ignition, and some characteristics of the spark plugs. A figure illustrates the meaning of the text and reference quantities of concern. This second edition cancels and replaces the first edition (1972).
Road vehicles — World parts manufacturer identifier (WPMI) code
Specifies the content and structure of an identifier in order to establish, on a world-wide basis, the identification of the manufacturers of parts for road vehicles; this identifier may serve, at the manufacturer's option, as a substitute or an addition for various national or international systems which already exist. Applies only to manufacturers of parts to be used on road vehicles as…
