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…
1. Scope
1.1 This Standard provides minimum requirements for the material characteristics and the fabrication of wood frames for doors with or without attached wood frames, i.e., sidelights and transoms.
Solid Mild Steel Filler Metals for Gas Shielded Arc Welding
1. Scope
1.1 This Standard prescribes requirements for solid mild steel filler metals*
for use with the Gas Metal-Arc (GMAW) process and also the Gas Tungsten Arc
(GTAW) and Plasma Arc Welding (PAW) processes.
This Standard is not intended to cover submerged-arc welding electrodes.
*When used for GMAW the filler metal is referred to as electrodes;
When used for GTAW and PAW the…
