Brown coals and lignites — Principles of sampling — Part 1: Sampling for determination of moisture c...
Part 1 of this standard presents the principles of methods for the sampling of brown coals and lignites from streams, wagons, barges and stock-piles which differ from those described in sampling of hard coals. Other general principles and the procedure of replicate sampling are the same as for hard coals.
Centrifuges — Construction and safety rules — Method for the calculation of the tangential stress in...
These construction and safety rules do not apply to the following centrifuges, which are expressively excluded from the field of application of this International Standard: centrifuges in which the kinetic energy of the loaded rotor is less than 750 J; centrifuges considered to be electric motor-driven domestic machines; centrifuges with a circumferential speed greater than 300 m/s; centrifuges…
Rubber or plastics hoses — Determination of volumetric expansion
Specifies a test method for hoses under hydrostatic pressure. When used for dispensing specific volumes of fluids, the volumetric capacity of a hose is often required to vary by only small amounts at the dispensing pressure. The standard describes a method of checking that such requirements can be met. A figure shows the arrangement of the apparatus.
Building construction — Modular coordination — Basic module
Establishes the value of the basic module, represented by the letter M, for use in modular coordination of buildings. Applies to the design and construction of buildings of all types in accordance with the principles and rules of modular coordination laid down in ISO 2848. The international standardized value of the basic module is 1 M = 100 mm.
Cinematography — Printed 8 mm, Type S, image area on 16 mm motion-picture film perforated 8 mm, Type...
This International Standard specifies the position and dimensions of the 8 mm, Type S printed picture areas for negative/positive and reversal printing on 16 mm motionpicture film perforated 8 mm, Type S, in positions 1 and 4.
Cinematography — Tape splices for 8 mm Type S motion-picture film for projector use — Dimensions
This International Standard specifies the dimensions of mated tut splices on 8 mm motion-picture film petforated 8 mm Type S made with a transparent adhesive tape. The specifications herein apply to magnetic and photographic Sound films as well as to silent films intended only for projection.
Chemistry — Layouts for standards — Part 3: Standard for molecular absorption spectrometry
Establishes a layout for standard methods of analysis of solutions in the visible and near ultra-violet regions. Gives some recommendations for their presentation and wording. The layout is preceded by a clause "Therminology and definitions", which supplements the information given in ISO 6286.
Radiographic image quality indicators for non-destructive testing — Principles and identification
The detection of an imperfection in a product subjected to X or gamma radiography depends on the quality of the resultant radiograph. This quality should be checked with an image quality indicator. This International Standard is intended for general application on all metals. However, for particular materials (for example, aluminium and its alloys) complementary International Standards may be…
Specifies the method for determining the ability of wire of diameter or thickness 0,1 to 10 mm inclusive to undergo plastic deformation during wrapping. The test consists of winding a wire to a specified number of turns around a mandrel of the diameter specified in the relevant standard to form a closely wrapped helix. It may also include a specified sequence of windings and unwindings, or even…
