Non-broadcast video tape recorders - Time base stability
Specifies the time base errors of the monochrome as well as of the colour composite video signal reproduced from two head helical-scan domestic video recorders, recording one field on each track. This standard gives characteristics and maximum figures of the time base errors to make it possible to design the horizontal flywheel of television receivers so as to ensure stability on the screen.
Semiconductor convertors - General requirements and line commutated convertors - Part 1-2: Applicati...
This report gives guidance on variations to the specifications in IEC 60146-1-1 to enable the specification to be extended in a controlled form for special cases. Background information is also given on technical points which should facilitate the use of IEC 60146-1-1.
It primarily covers line commutated convertors and is not in itself a specification, except as regards certain auxiliary…
Fixed capacitors for use in electronic equipment - Part 13: Sectional specification: Fixed polypropy...
Relates to fixed direct-current capacitors, using as dielectric a
polypropylene film and electrodes of thin metal foils. Capacitors
for reactive power exceeding 500 var are not covered by this
standard. Prescribes preferred ratings and characteristics, selects
from IEC 60384-1 the appropriate methods of test and gives general
performance requirements for this type of capacitor.
Clutch housings for reciprocating internal combustion engines — Nominal dimensions and tolerances
Specifies the nominal dimensions and tolerances which affect the interchangeability between clutch housings for spring-loaded clutches and mating parts. All other dimensions and tolerances are left to the discretion of the component manufacturer. Does not apply to engines for aircraft and passenger cars; it may be used for other engine applications where no specific International Standard exists…
Caravans and light trailers — Trailers of categories 01 and 02 with overrun brakes — Inertia bench t...
This second edition cancels and replaces the first edition (ISO 7642:1983), of which certain values have been altered, the previous clause 8 deleted and references updated. Specifies test methods for type approval testing of the overrun brakes that relate to mechanically and hydraulically operated braking systems. Should therefore be used in connection with the pertinent regulation. It is…
This standard applies to glass intended for installation in spandrel areas of
building exteriors. It also provides requirements so that such glass shall not
pose a safety hazard in a specific application for which it is supplied.
Functional and Compatibility Requirements for Private Branch Exchange (PBX)
Switching Equipment for...
For the purposes of this standard, the PBX is considered to be a
device that performs switching functions between station
apparatus interfaces and between the station apparatus interfaces
on one side and central office (CO) and special trunk interfaces
on the other.
Information technology — SGML and Text-entry Systems — Guidelines for SGML Syntax-Directed Editing S...
Specifies a set of functions which an SGML syntax-directed editing system may have in order to help users manipulate documents. Contains two major clauses. The first one describes the functions on an SGML syntax-directed editing system as applied to document processing. The second clause identifies those additional facilities felt to be appropriate for DTD processing. Does not specify a "…
