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…

1. Scope 1.1 This Standard applies to reagent kits which employ a radioimmunoassay for the measurement of total triiodithyronine [T3 (RIA)] in human blood. 1.2 This Standard defines minimum requirements for the performance, labelling, testing and evaluation of such reagent kits. Note: Labellling requirements are intended to supplement the general provisions of Medical Devices…

1. Scope 1.1 General This Standard covers the load test procedure for evaluating the strength and deformation performance of wood roof trusses intended for use in housing and small buildings as defined in Part 9 of the National Building Code of Canada. Note: Part 9 of the National Building Code of Canada provides detailed requirements…

1. Scope 1.1 This Standard applies to stationary, electrically heated, warm air, central furnaces of the forced-air type that discharge air into ducts extending not less than 30 inches downstream from the heater elements, for use on nominal system voltages of 600 V and less, designed to be used in non-hazardous locations in household, commercial, and industrial applications, in accordance…

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. The smallest insulator unit standardized has a lighting impulse withstand voltage…
