1. Scope 1.1 This Standard applies to portable luminaires for general household, commercial, and industrial use in dry, damp, and outdoor locations, and intended to be used in accordance with the Rules of the Canadian Electrical Code, Part I, in non-haz ardous locations, on a nominal 120 V system. Throughout this Standard the term portable luminaires has been shortened to luminaires…

1. Scope 1.1 This Standard applies to single-phase and 3-phase dry-type transformers within the limits of the electrical ratings listed in Clauses 6.2 and 6.3, and intended to be used in accordance with the service conditions for dry-type transformers outlined under Appendices A and B. Note: For information on the loading of dry-type transformers see CSA Standard C9.1, Guide for Loading…

This International Standard specifies the dimensions for 8 mm Type S motion-picture projection reels/spools of 75 to 312 mm diameter (with the exception of the 75 mm Type No. 7) that are interchangeable on all types of reel-to-reel projection equipment. NOTE - The No. 7 reel (75 mm), although temporarily recognized, will be superseded by that specified in ISO 6033. lt is recommended that new…

1. Scope 1.1 This Standard sets forth the characteristics of an instrument conforming to the requirements of ANSI Standards C63.2, Ra dio-Noise and Field-Strength Meters 0.015 to 30 Megacycles/Second, and C63.3, Radio-Noise and Field-Strength Meters 20 to 1,000 Megacycles/Second, for the measurement of electromagnetic interference, both conducted and radiated, in the frequency range 0.15…

1. Scope 1.1 This Standard applies to the continuous measurement of ozone in air. 1.2 This Standard sets forth the chemiluminescence method for the measurement of concentrations of ozone between 2 µg·m-3 and 10 mg·m-3 at 25°C and 101.3 kPa (approximately 0.001 ppm v/v and 5 ppm v/v). Notes: (1) All concentrations referred to throughout this Standard are based on a temperature…

1. Scope 1.1 This Standard describes the investigations required to obtain the seismological and geological information necessary to determine, for a proposed CANDU nuclear power plant site, the seismic ground motion that will be utilized in seismic qualification of safety-related plant structures and systems, and the potential for seismically induced phenomena that may have a direct or…

1. Scope 1.1 This Standard applies to the mechanical features of new and remanufactured power-operated dispensing devices for petroleum- base liquids for use as fuel in internal combustion engines where such devices are intended primarily to dispense the liquid directly into the fuel storage tank of the engine. 1.2 This Standard does not cover associated nozzles or hose, nor does it…

1. Scope 1.1 This Standard is primarily concerned with the nuclear safety of Shutdown Systems, i.e., their ability to terminate the nuclear reaction during a potentially hazardous situation. However, it recognizes that the repeated unnecessary operation of a Shutdown System will needlessly stress the nuclear plant and, possibly, lead to earlier system and component failures. Therefore, this…

1. Scope 1.1 This Standard applies to the measurement of the concentration of sulphur dioxide in air. 1.2 This Standard sets forth the Pararosaniline Colorimetric Procedure based on the West-Gaeke Method as the reference method for the measurement of sulphur dioxide in the range 25 to 1000 µg·m-3 at 25°C and 101.3 kPa. Note. All concentrations referred to throughout this Standard…

1. Scope 1.1 This Standard applies to add-on heat pumps for comfort heating or heating and cooling not exceeding 20 kW in the cooling mode and rated at 600 V or less, single or polyphase, intended to utilize the fan assemblies and duct work of the existing installed furnaces to form the complete functional systems where the existing parts are not covered by this Standard. Note: For…
