Applies to passive, two-wire, externally powered pulse output devices to be used in electricity meters as defined by the relevant standards of technical committee 13 as well as future standards for static VA-hour meters. Such pulse output devices are used to transmit pulses to a receiver (e.g. a tariff device). This publication is of high relevance for Smart Grid.

Applies to tape spools used with video recorders for broadcast purposes. Standardizes the spools used in the various broadcast video recording formats.

Is applicable to three-phase, alternating current switches and switch-disconnectors having making and breaking current ratings, for indoor and outdoor installations, for rated voltages above 1 kV and less than 52 kV and for rated frequencies from 16 2/3 Hz up to and including 60 Hz. This standard is also applicable to the operating devices of these switches and to their auxiliary equipment. The…

Relates to connectors for r.f. transmission lines and serves as a generic specification providing the basis for the sectional standards which apply to individual connector types. Establishes uniform concepts and procedures concerning: -terminology; -standard ratings and characteristics; -testing and measuring procedures concerning electrical and mechanical properties; -classification of…
