1. Scope and Objective 1.1 This Standard applies to wet-process porcelain and toughened glass suspension-type insulators used on ac overhead power lines with a nominal voltage greater than 1000 V and a frequency not greater than 100 Hz. This Standard applies to single insulator units only. This Standard does not apply to long rod insulators. 1.2 The objective of this Standard is…

For specific information see individual standards in the series. Sets forth requirements for materials, analysis of materials, and operational practices for pressure and thermal impregnation for the chemical preservation of wood.

Is intended as a guide to purchasers and specifiers of treated forest products in order that a better treatment product will result from the use of CAN/CSA-O80 Series, Wood Preservation. Terms which are not familiar to the reader may be found in the Glossary of AWPA Standard M5.

Covers the preservative treatment of round, half-round, and quarter-round posts* for fence or highway use. It does not cover the preservative treatment of posts sawn four sides. Sawn posts are treated under CSA Standard CAN/CSA-O80.2. *Posts, in contrast with poles, cover lengths shorter than 4.5 m.

This National Standard of Canada is equivalent to International Standard ISO 8823-1988. It specifies: a) procedures for the transfer of data and control information from one presentation-entity to a peer presentation-entity; b) the means of selecting, by means of functional units, the procedures to be used by the presentation-entities; c) the structure and encoding of the…

This National Standard of Canada is equivalent to International Standard ISO 8822-1988. It defines (in an abstract way) the externally visible service provided by the OSI Presentation Layer in terms of: a) the primitive actions and events at the user/service boundary; b) the parameter data associated with each primitive action and event; c) the relationship between, and the valid…

1. Scope 1.1 This Standard applies to Christmas tree and other decorative lighting outfits, intended for connection to circuits of 125 V or less between conductors by means of an attachment plug cap, and designed to be used in accordance with the rules of the Canadian Electrical Code, Part I. 1.2 This Standard applies to indoor or outdoor outfits for illuminating Christmas trees and…

This TTD covers the essential elements of future international standardization of UMF types.

This standard gives methods of test for the determination of the short-time electric strength of solid insulating materials at power frequencies: that is, those between 48 Hz and 62 Hz.

1.1 This standard applies to two types of vapour barrier jacket and facing material comprised of aluminum foil, glass fibre scrim and paper laminated with adhesive, for use in the temperature range of -20 to 65 degrees C over thermal insulation for pipes, ducts and equipment. 1.2 For more detailed information on intended uses, see par. 8.2.
