Animal and vegetable fats and oils — Determination of water content — Entrainment method
The method is applicable to products having water content greater than or equal to 0,5 % (m/m). It consists in entraining of the water present in a test portion, by azeotropic distillation with the aid of an organic liquid not miscible with water, and measuring of the volume of water collected. A figure shows a suitable distillation apparatus.
Tea — Preparation of ground sample of known dry matter content
The method consists in grinding of the sample, and determination of the dry matter content of the ground sample by heating a test portion in an oven at 103 +/-2 degrees centigrade to constant mass.

Performance standards in building — Contents and presentation
Specifies the basic contents to be included in performance standards for building components and assemblies, and indicates a standard order for their inclusion. Is intended primarily for use by standards committees preparing performance standards for building components and assemblies. Should also be useful for the preparation of other types of documents.
Sodium hexafluorosilicate for industrial use — Determination of free silica content — Gravimetric me...
Covers a method, the principle of which is based on the extraction from a test portion of compounds soluble in acetic acid solution and weighing of the residue after heating at 600 °C, removal from the residue, of silica by evaporation with hydrofluoric acid solution and of residual fluorides by heating with ammonia solution, and reweighing of the residue after heating at 600 °C. Is applicable to…
Ferrovanadium — Determination of vanadium content — Potentiometric method
The method applies to alloys having a vanadium content less than or equal to 85 % (m/m). Specifies principle, reagents, apparatus, sample, procedure, expression of results, repeatability and test report.
