Dimensions for panel-mounted indicating and recording electrical measuring instruments
Defines a system of dimensions for electrical and electrically operated indicating measuring instruments of the panel type. The aim of this recommendation is to promote interchangeability of panel-mounted instruments and for this purpose a modular system based on the module of 12.5 mm has been established.
Dimensions pour appareils de mesure électriques indicateurs et enregistreurs de tableau
Définit un système de dimensions pour appareils de mesure électrique et appareils électriques de mesure de tableau du type indicateur. Cette recommandation a pour but de favoriser l'interchangeabilité des appareils montés sur panneau et, à cet effet, il a été établi un système modulaire fondé sur le module de 12,5 mm.
Dimensions of clevis and tongue couplings of string insulator units
Applies to string insulator units of the can and pin type and also of the long rod type as well as to the fittings used with such insulators. Defines dimensions of a series of clevis and tongue couplings to permit the assembly of insulators or fittings supplied by different manufacturers.
Note: - For co-ordination between standardized dimensions and strength classes of cap and pin type…
Specifications for pressure-sensitive adhesive tapes for electrical purposes - Part 1: General requi...
Specifies general requirements for pressure-sensitive adhesive tapes for electrical purposes. Particular types of tape are designated by using the code letters for the form and nature of backing material given in a new table, followed by the figures for temperature index and code letters for the adhesive, as indicated in an updated table.
Environmental testing - Part 3: Background information - Section
One: Cold and dry heat tests
Gives background information for Tests A: Cold (IEC 68-2-1), and
Tests B: Dry heat (IEC 68-2-2). Includes appendices on the effect
