Specifies the general operating characteristics and standardization principles. Does not define a specific pattern for the connection system from the point of view of dimensions, but lays down limits for the design and performance for each system. This part lays down the basic requirements for the mechanical structure and electrical performances as well as the basic environmental conditions in…

Covers both the male end dimensions, and the female end dimensions. The pitch p/ps as given in the tables defines the spline dimensions. The first number is the diametral pitch; the second number is the stub pitch; it denotes, as the fractional part of an inch, the basic radial length of engagement, both above and below the pitch circle. The module denotes the number of units of pitch diameter…

Defines the procedures for determining the exterior A-weighted equivalent continuous sound power level, A-weighted exterior sound pressure levels, and operator A-weighted sound pressure levels emitted by construction, forestry, and mining machinery with net engine power greater than 15 kW. The categories of machinery covered by this Standard are tractor, loader, dumper, tractor-scraper,…

Applies to non-perforated magnetic tape used for professional and domestic analogue sound recording and reproduction. Lists and defines the methods of measurement and equipment necessary to determine the mechanical characteristics of magnetic recording tape. Will also enable users of magnetic tapes to compare technical product data of different manufacturers, produced in accordance with this…

Applies to electronic indirect a.c. convertor systems with electrical energy storage means in the d.c. link. Defines a complete uninterruptible power system in terms of its performance and not in terms of individual sub-system functional units.

Defines the grades of cold-rolled non-oriented magnetic steel sheet and strip in nominal thicknesses of 0.35 mm, 0.47 mm, 0.50 mm and 0.65 mm. In particular, it specifies general requirements, the magnetic properties, geometric and technological characteristics, as well as the inspection procedure.

Defines equipment, methods and procedures for obtaining laboratory measurements of airborne sound-pressure levels radiated by control valves and/or associated piping configurations, including fixed restrictions, through which compressible fluids are passing. Provides a method of testing the noise-generating characteristics of control valves. The noise characteristics to be determined are useful…

1. Scope 1.1 This Standard contains the requirements for the quality assurance program applicable to the commissioning phase of a nuclear power plant. 1.2 This Standard embodies the relevant quality assurance requirements of CSA Standard CAN3-N286.0, and is the governing Standard for commissioning quality assurance activities in the event of any conflicting requirements. 1.3…

Lays down the basic dimensions and tolerances in millimetres for theses round punches in the diameter range 1 to 32 mm. Gives matrial and ahrdness as examples, and specifies the designation of punches. The main use of punches defined in ISO 8021 is for punching holes in steel sheet or in sheet of other materials.

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…
