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…

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…

Covers the performance requirements of two types of sheet materials suitable for use in controlling the movement of water vapor in building construction. Material to this standard is primarily intended for use in above-grade building construction and on the interior of below grade building construction. This standard is not intended to apply to vapor barrier materials for use under concrete…

Includes the dimensions of relays with a rated breaking capacity equal to 2 A or 3 A. Applies to the relays currently used for aircraft electrical power systems. The characteristics of these relays will be defined in a future International Standard.

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…
