Applies to highly reliable software required for computers to be used in the safety systems of nuclear plants for safety functions (Class 1 functions according to IEC 643). This includes the safety actuation systems, the safety system support features and the protection systems. This standard provides requirements for each stage of software generation, including design, development, qualification…

Specifies a method for the determination of compressive creep of rigid cellular plastics under specified conditions of load, temperature and time. Test specimes in form or rectangular parallelepipeds are placed between two flat plates and the specified load is applied a) at standard conditions and b) at agreed conditions of temperture and time. The difference in compressive deformation of the…

Scope 1.1 General 1.1.1 This Standard applies to the continuous measurement of the concentrations of (a) oxygen (O2) (see Clause 6.1); (b) carbon dioxide (CO2) (see Clause 6.2); (c) carbon monoxide (CO), (see Clause 6.3); (d) sulphur dioxide (SO2) (see Clause 6.4); and (e) nitrogen oxides (NOx); in a continuously extracted sample of combustion gases from an enclosed gas…

1. Scope 1.1 General This Standard applies to (a) reagents and apparatus for preparing dialysing fluid; (b) monitors of the dialysing fluid; (c) accessories for monitoring the extracorporeal blood circuit; and (d) blood pumps, infusion, and single needle systems. Notes: (1) Examples of reagents and devices included within the Scope of this Standard are dialysis concentrate and…

1. Scope 1.1 This Standard prescribes a method for determining heat outputs, appliance efficiencies, emission levels and composition, and flue gas flow rates for wood-fired appliances with a closed fire chamber. 1.2 For the purpose of this Standard, a wood-fired appliance with a closed fire chamber is one in which the air-fuel ratio is less than 30:1 by weight during the burning of at…

1. Scope 1.1 This Standard applies to stationary electric duct heaters for comfort heating rated at 600 V or less and 1000 kW and less, designed to be installed and used in nonhazardous locations in residential, commercial, and industrial applications, in ac cordance with the Canadian Electrical Code, Part I. Note: The Canadian Electrical Code, Part I, provides a limitation of 150 V to…

1. Scope 1.1 This Standard applies to insulating tubing that consists entirely of extruded compounds (see Table 1 for materials, sizes, and ratings) and also applies to heat-shrinkable tubing (with or without a meltable liner) intended for use in equipment designed to be used in accordance with the Rules of the Canadian Electrical Code, Part I, at a voltage not exceeding 1000 V. 1.2…

Specifies a method for the determination of compressive creep of rigid cellular plastics under specified conditions of load, temperature, relative humidity and time. Test specimes in form or rectangular parallelepipeds are placed between two flat plates and the specified load is applied as follows: procedure A) at standard conditions and procedure B) at agreed conditions of temperture and time.…

This standard applies to silvered mirrors of polished plate, float or sheet glass. Classification according to end use provides for normal, high humidity and wardrobe door applications.

1. Scope 1.1 This Standard applies to manually operated and mechanically operated special use switches that are: (a) for use on dc, ac/dc or ac only; and (b) rated for not more than (i) 60A at 250V or less; or (ii) 30A or 2hp at 600V or less. 1.2 This Standard does not apply to (a) switches forming parts either of electrothermal appliances or automatic temperature-responsive switches; (b)…
