Anhydrous hydrogen fluoride for industrial use — Sampling
This part contains a method for taking laboratory samples intended for the determination of the water content and the preparations of the test samples. Contains instructions for handling with the material. Applicable for taking samples of this highly corrosive liquid from road and rail tanks, drums and cylinders. The principle consists in allowing the liquid of one of these containers to flow in…
Anhydrous hydrogen fluoride for industrial use — Determination of non-volatile acid content — Titrim...
Applicable to contents of between 0.005 % (m/m) and 0.3 % (m/m) expressed in sulphuric acid. Preparation of the samples according to ISO 3137. Removal of volatile acids by evaporation and titration of the remaining acidity with standard volumetric sodium hydroxide solution in the presence of phenolphthalein as indicator. The evaporation is carried out on a boiling water bath in a fume cupboard.
Carbon disulphide for industrial use — Sampling and methods of test
Specifies also the determination of density at 20 0C and the measurement of colour in Hazen units. Details the determination of distillation characteristics, residue on evaporation and inorganic sulphur content. Has also been approved by the IUPAC.
Sodium tripolyphosphate and sodium pyrophosphate for industrial use — Determination of orthophosphat...
Specifies a photometric method, using the reduced molybdophosphate, for the determination of orthophosphate content of sodium tripolyphosphate and sodium pyrophosphate for industrial use. Applicable to products with orthophosphate contents between 0,05 and 1,0 % (m/m).
