the preparation and use of quality standards and for mutual
understanding in international communications.
Cheese and processed cheese products — Determination of fat content — Gravimetric method (Reference ...
Describes a method based on the Schmid-Bondzynski-Ratzlaff principle which consists in digesting a test portion with hydrochloric acid, adding ethanol and subsequently extracting the acid-ethanolic solution with diethyl ether and light petroleum, removing the solvent by distillation or evaporation, and determining the mass of the substances extracted which are soluble in light petroleum. The…
Milk products and milk-based foods — Determination of fat content by the Weibull- Berntrop gravimetr...
The method is applicable especially to those products containing distinct quantities of free fatty acids or those which are not completely soluble in ammonia owing to the presence of lumps or non-milk ingredients, such as custards, porridges, etc. The method is also applicable to fresh cheese types. It consists in digesting of a test portion by boiling with dilute hydrochloric acid, filtrating of…
Milk products and milk-based foods — Determination of fat content by the Weibull- Berntrop gravimetr...
Specification of a method to those products, that may containe more than 5% (m/m) (in the dry matter) of dextrin, or vegetable, fruit, meat, etc. It consists in digesting of a test portion by boiling with dilute hydrochloric acid, filtrating of the hot digest through a wetted filter paper, extracting of the fat from the dried filter paper using n-hexane or light petroleum, removing of the solvent…
Iron ores — Determination of combined water content — Karl Fischer titrimetric method
This method ist applicable to a concentration range of 0,05 to 10 % (m/m) of combined water in natural iron ores, and iron ore concentrates and agglomerates including sinter products. The term combined water means that part of the water content of an iron ore that can be removed only at temperatures substantially higher than 100 to 110 °C. Figures show the general arrangement of the test…
Iron ores — Determination of arsenic content — Molybdenum blue spectrophotometric method
The method ist applicable to a concentration range of 0,0001 to 0,1 % (m/m) (1 bis 1000 /g) of arsenic in natural iron ores, and iron ore concentrates and agglomerates including sinter products. Specifies principle, reagents, apparatus, sampling and samples, procedure, expression of results, and test report. Includes three annexes. A figure shows the arsenic distillation apparatus.
