This International Standard specifies - the conditions for conformance testing; - the environments in which the cartridges are to be operated and stored; - the mechanical, physical and dimensional characteristics of the case and of the cartridges, so as to provide mechanical interchangeability between the data processing systems; - the format of the information on the disk, both embossed and user…

Specifies the characteristics (dimensions, specifications, designation) for screws having threads from M1,6 up to and including M24 and of product grade A. If, in special cases, specifications other than those listed are required, they should be selected from existing international standards, e.g., ISO 261, ISO 888, ISO 898-5 and ISO 965-2. Annex A describes gauging of hexagon socket.

The procedure includes weighing out a test portion of approximately 300 g of the sample, placing the test portion in the top sieve of a set of test sieves (including all the sieves listed against the grade under test in the appropriate part of ISO 11126) with the largest-aperture sieve on the top and progress to the smallest aperture at the bottom with a pan, to catch any abrasive that falls…

The procedure includes drying a sufficient quantity of the sample by heating, allowing to cool to room temperature, adding distilled or deionized water to the cleaned, dried and weighed pyknometer containing 10 g of the dried sample until it is completely filled, displacing air adhering to the test portion, drying the outside of the pyknometer, reweighing the pyknometer and its contents, emptying…

The procedure includes examining a small quantity of the sample under the microscope and, if grains of different colours or diameter are present, selecting a few grains of each, placing the selected grains between two glass microscope slides and, whilst applying pressure, slowly moving one slide over the other with a reciprocating motion for 10 s, examining the glass surfaces for scratches. The…

The procedure includes weighing a test portion of approximately 100 g into a container, placing the container with the test portion in an oven previously adjusted to 110 °C, leaving for at least 1 h, transferring the container to a desiccator, allowing to cool to room temperature, reweighing the container with the dried test portion, determining the mass of the dried test portion. Annex A gives…

The procedure includes weighing a test portion of 100 g of the sample, adding 100 ml of the conductivity water, shaking, allowing to stand, filtering if necessary, transferring sufficient of the liquid to fill the conductivity cell of the conductivity-measuring bridge, and measuring the conductivity of the solution. Annex A gives information on the international standards series for non-metallic…
