Applies to digital ratemeters used in nuclear instrumentation to measure periodic or random pulse counting rates as produced by detectors. Defines the characteristics used for expressing functional performance and establishes the test methods recommended for measuring and verifying such characteristics.

1. Scope 1.1 The Standard is concerned with two aspects of the reactor regulating system. The first relates to reactor safety; the second is concerned with effective control of the reactor. These two aspects are not separate. This Standard, therefore, addresses itself to two points: (a) To ensure that the reactor regulating system operates to limit, to acceptable values, the frequency…

This Standard provides the requirements for the design of concrete containment structures of a containment system, designated as "class containment" components and parts, as defined in CSA Standard CAN3-N287.1, General Requirements for Concrete Containment Structures for CANDU Nuclear Power Plants.

ISO 2721:1982 defines the exposure at the focal plane of cameras for values of two exposure parameters, i.e. field luminance and film speed. It also gives methods of evaluating other photometric characteristics. The data apply to automatic exposure control systems which are built into cameras or coupled with them to regulate the exposure in the focal plane in dependence of the various exposure…

Covers non-ferrous metallic pneumatic cylinder tubes. Defines the mechanical properties, dimensional tolerances, surface finishes, and technical delivery conditions of the following tubes and bores for pneumatic fluid power cylinders: round non-ferrous metallic tubes, seamless or welded type, in the as-drawn stress-relieved or fully heat-treated condition; bores, specially finished, with or…

Applies to one-component joint sealing compounds that cure to a rubber-like solid and are suitable for sealing, caulking or glazing applications. A sealing compound meeting the requirements of this standard is designated by the manufacturer to be one or more of the types, classes, grades, and uses defined in Section 3 of this standard. For application on a particular substrate the primer,…

This part defines the machining operations that can be carried out an these machine tools. Describes the different types of machines: planer type machines, and movable column machines or floor type machines. Gives the terminology for the main elements of the machine (in English, French and Russian as well as equivalent terms in German and Italian.)

Describes a method based on a number of international collaborative studies carried out over a long period of time. The method seeks to optimize a number of variables in an attempt to define procedures and provide a common measure of the pungency of pepper. The principle consists in the extraction of the pungent compounds with ethanol and spectrophotometric measurement at 343 nm.

Defines devices for measuring parameters of ignition systems of internal combustion engines in road vehicles, and their possible methods of use. Applies to plug-in and built-in sensors for exclusively diagnostic purposes. Some figures illustrate diagrams as well as sensor and gauge of concern.

Attention is drawn to the fact that this Technical Report only regards recommendations which do not have any restrictive nature nor do they require the replacement of existing regulations which have proved their worth in the past. Applies only to external gear pairs with parallel axes of which the teeth of spur and helical gears are defined by the standard basic rack tooth profile in conformity…
