Prescribes specified values for the electrical and mechanical characteristics and for the principal dimensions of string insulator units of the long rod type with insulating parts of ceramic material intended for a.c. overhead lines with a nominal voltage greater than 1 000 V and a frequency not greater than 100 Hz. It is also applicable to insulators of similar design, used in substations.…

This National Standard of Canada is based on International Standard CEI/IEC 1008-1: 1990, (first edition, 1990-12), with Corrigendum 1990 and Amendments 1:1992 and 2:1995. 1. Scope This International Standard applies to residual current operated circuit-breakers functionally independent of, or functionally dependent on, line voltage, for household and similar uses, not incorporating…

This National Standard of Canada is based on International Standard CEI/IEC 926:1995 1. Scope This standard specifies general and safety requirements for starting devices (starters and ignitors) for tubular fluorescent and other discharge lamps for use on a.c. supplies up to 1 000 V at 50 Hz or 60 Hz which produce starting pulses not greater than 100 kV and which are used in combination…

This National Standard of Canada is equivalent to International Standard CEI/IEC 61010-2-042: 1997. 1 Scope and object This clause of part 1 is applicable except as follows: 1.1 Scope Replacement: This standard applies to AUTOCLAVES and STERILIZERS, including those with an automatic loading and unloading system, which incorporate a CHAMBER using toxic gas intended for the treatment of…

This International Standard specifies the characteristics of a range of steel roller chains, dimensionally derived from the malleable iron type and suitable for the conditions of operation and maintenance prevailing in such fields as agriculture, building, quarrying and related industry, mechanical handling, etc., and of associated chain sprockets.

This is a searchable PDF. 1. INTRODUCTION 1.1 General. This standard has been developed to identify performance requirements for pressure relief devices for Natural Gas Vehicle (NGV) fuel containers. This standard sets minimum requirements for pressure relief devices produced for use on NGV fuel containers. NGV fuel containers comply with ANSI/IAS NGV2, Basic Requirements for Compressed…

This International Standard specifies certain characteristics of oil of turpentine, Iberian type (Pinus pinaster Sol.), in order to facilitate assessment of its quality.

1 General 1.1 Scope This part of IEC 71 constitutes an application guide and deals with the selection of insulation levels of equipment or installations for three-phase electrical systems. Its aim is to give guidance for the determination of the rated withstand voltages for ranges I and II of IEC 71-1 and to justify the association of these rated values with the standardized highest…

Gives the requirements for one type of heat-shrinkable, flame retarded, fluid resistant, elastomer sleeving with temperature index of 120 and a nominal shrink ratio of 2:1. This sleeving is normally supplied with internal diameter up to 51 mm and the standard colour is black.
