1.1 This Standard applies to equipment for installation and use in accordance with the Rules of the Canadian Electrical Code, Part I, other than conduit couplings. 1.2 This Standard includes basic construction and inspection requirements for the threaded entry for conduit into an electrical enclosure in order to assure the following: a) the adequacy of a grounding path provided by rigid…

1.1.1 This Standard addresses quality assurance requirements for software used in design, safety analysis, and supporting activities. 1.1.2 This Standard specifies the requirements for the quality assurance program applicable to the design, development, maintenance, modification, acquisition, and use of analytical, scientific, and design computer programs that are used in high energy reactor…

1.1 This Standard uses principles of insulation coordination in specifying through-air and over-surface spacing requirements for electrical equipment used in accordance with the Rules of the Canadian Electrical Code, Part I. 1.2 The complete principles of insulation coordination involve consideration of a combination of clearances, creepage distances, and properties of solid insulation used…

1.1 This Standard covers electrically operated household clothes dryers and specifies two separate energy performance test methods. The first procedure relies on operator intervention to manually end the test; the second procedure relies on the dryer’s automated termination control. This Standard also specifies minimum energy efficiency levels. 1.2 This Standard applies to electrically operated…

This test method is a standard procedure for the determination of paraffins, olefins, naphthenes, aromatics and unknowns (P.O.N.A.U.) in automotive gasolines using gas chromatography and flame ionization detection (GC/ FID). Group types are determined by summing individual components. Individual hydrocarbon components greater than or equal to 0.01% by mass are determined. Oxygenated…
