Specifies recommended scales to be used on drawings for
engineering, architectural, construction, surveying and mapping
purposes. The standard also makes recommendations on the choice
and presentation of scales.
This fire test method is applicable to door assemblies of various
materials and types of construction, for use in wall openings to
retard the passage of fire. It is the intent that tests made in
conformity with this standard will develop data to enable
regulatory bodies to determine the suitability of door assemblies
for use in locations where fire resistance of a specified
duration is…
General Requirements for Seismic Qualification of CANDU Nuclear Power Plants
1. Scope
1.1 General This Standard sets forth the general requirements for seismic qualification of CANDU Nuclear Power Plants. ,, It applies to all structures and systems of the CANDU Nuclear Power Plant that require seismic qualification based on nuclear safety considerations. ,,
1.2 This Standard may also be applied to such other structures and syst ems of a nuclear power plant as…
Requirements for the Shutdown Systems of CANDU Nuclear Power Plants
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…
Pulps — Determination of drainability — Part 2: "Canadian Standard" freeness method
Provides a measure of the rate at which a dilute suspension may be dewatered and is applicable to all kinds of pulp in aqueous suspension. Test results do not necessarily correlate with the drainage behaviour of pulp material on a commercial paper machine.
Chemical products for industrial use — General method for determination of traces of sulphur compoun...
Describes a method based on prior conversion of the sulphur compounds in a test portion to sulphate, if required, and reduction of the sulphate ions ti hydrogen sulphide by a mixture of hydriodic and phosphinic acids in the presence of hydrochloric acid. The hydrogen sulphide is entrained in a current of nitrogen and absorbed in a solution of sodium hydroxide in aqueous acetone, followed by…
The Standard specifies certain characteristics of the oil. The oil shall be clear and almost colourless to pale yellow, the odour characteristic, recalling cineole. The relative density at 20/20 °C has to ly between 0,906 and 0,925 and the refractive index at 20 °C between 1,4590 and 1,4670. The optical rotation shall range from 0 to + 10 . 1 volume of the oil shall not require more than 5…
