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…

The procedure includes weighing a test portion of 100 g of the sample, adding 100 ml of water, shaking, allowing to settle, filtering if necessary, adding sulfuric acid to 25 ml of the solution, diluting, titrating the solution with silver nitrate, and noting the end point. Annex A gives information on the international standards series for non-metallic blast-cleaning abrasives ISO 11126 and ISO…

Specifies a test method for the determination of particles with cracks, laminations, voids and shrinkage, of defectively shaped shot, grit and cylindrical particles, of microstructure using a microscope. Annex A gives information on the international standards series for metallic blast-cleaning abrasives ISO 11124 and ISO 11125.

Specifies a test method for the determination of particles with cracks, laminations, voids and shrinkage, of defectively shaped shot, grit and cylindrical particles, of microstructure. Annex A gives information on the international standards series for metallic blast-cleaning abrasives ISO 11124 and ISO 11125.

Specifies a test method for the determination of the level of free moisture present determined by measuring the mass lost on heating. Annex A gives information on the international standards series for metallic blast-cleaning abrasives ISO 11124 and ISO 11125.

Specifies a test method for the determination of particle size distribution by sieving. The procedure includes weighing out a test portion of 100 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 11124) with the largest-aperture sieve on the top and progress to the…

Specifies a test method for the determination of the Vickers hardness (using a test force of 9,807 N, i.e. HV 1, when testing particles with a diameter greater than 0,5 mm, and a test force of 4,904 N, i.e. HV 0,5, when testing particles with a diameter of 0,3 mm to 0,5 mm). The method is not recommended for the testing of particle sizes below 0,3 mm. The purpose is to establish the soundness of…

Specifies a test method for the determination of apparent density using a pyknometer. The purpose is to establish the soundness of the metallic abrasive. Significant levels of internal shrinkage or hollow particles will reduce the apparent density. Annex A gives information on the international standards series for metallic blast-cleaning abrasives ISO 11124 and ISO 11125.

Specifies methodologies for the evaluation of the systemic toxicity potential of medical devices which release constituents into the body. Includes, in addition, pyrogenicity testing. The methods cited are from international standards, national standards, directives and regulations.

States and defines the principal performance characteristics for mens electric shavers (rotary and vibratory) which are of interest to the user, and describes standard methods for measuring these characteristics.
