Sodium hexafluorosilicate for industrial use — Determination of sulphur compounds content — Iodometr...
Applicable to products having contents, expressed as sulphate2- , between 0.03 % (m/m) and 0.5 % (m/m). Reduction of the compounds to hydrogen sulphide by heating with a mixture of hydriodic and hypophosphorus acids in the presence of hydrochloric acid. Entrainment of the hydrogen sulphide in a flow of nitrogen and absorption in an excess of ammoniacal cadmium acetate solution. Liberation of the…

Anhydrous hydrogen fluoride for industrial use — Determination of water content — Conductimetric met...
Suitable for use as a routine alternative to the Karl Fischer method specified in ISO 3699 but may give a lower standard of accuracy. Applicable to products having a water content between 0.01 % (m/m) and 0.4 % (m/m). Bases on the measurement of the conductance of anhydrous products using a dip cell electrode. Determination of the corresponding content by means of a calibration graph making a…
Procedure for In-Situ Measurement of Noise From Industrial Equipment
1. Scope
1.1 This Standard covers procedures for the measurement of airborne sound originating from industrial equipment in the working environment rather than in a standardized environment.
1.2 This Standard describes the following three procedures:
(a) A procedure for determining the A-weighted sound levels at representative points around the equipment (see Clause 5);
(b) A…
Sodium hexafluorosilicate for industrial use — Determination of particle size distribution — Sieving...
Describes a method intended to assess the suitability of powdered mateial for volumetric feeding device and the potential dust hazard. The principle consists in sieving a test portion through a nest of sieves and determining the masses retained on each sieve. The result is then calculated as percentages passing through the different sieves.
