Animal feeding stuffs - Determination of nitrogen content and calculation of crude protein content - Part 2: Block digestion/steam distillation method (ISO 5983-2:2005); German version EN ISO 5983-2:2005

DIN EN ISO 5983-2-2005 发布历史

This part of ISO 5983 specifies a method for the determination of nitrogen content of animal feeding stuffs according to the Kjeldahl method, and a method for the calculation of the crude protein content. It concerns a semi-micro rapid routine method using block-digestion, copper catalyst and steam distillation into boric acid. The method is applicable to the determination of greater than 0,5 % Kjeldahl nitrogen in animal feeding stuffs, pet foods and their raw materials. The method does not measure oxidized forms of nitrogen nor heterocyclic nitrogen compounds. The method does not distinguish between protein nitrogen and non-protein nitrogen. NOTE If it is of importance to determine the content of non-protein-nitrogen, an appropriate method can be used.

DIN EN ISO 5983-2-2005 在中国标准分类中归属于: B46 畜禽饲料与添加剂，在国际标准分类中归属于: 65.120 饲料。
