标准摘要
[中文适用范围]： 本部分ISO 16634规定了一种测定油籽和动物饲料中总氮含量并计算粗蛋白含量的方法。该方法与凯氏定氮法一样，不区分蛋白质氮和非蛋白质氮。计算蛋白质含量时使用各种转换系数（见附录D）。该方法不适用于牛奶和乳制品，其方法在ISO 14891⎪IDF 185中规定。 [外文原描述]： ISO 16634-1:2008 specifies a method for the determination of the total nitrogen content and the calculation of crude protein content of oilseeds and animal feeding stuffs. This method, like the Kjeldahl method, does not distinguish between protein nitrogen and non-protein nitrogen. For the calculation of protein content, various conversion factors are used. This method is not applicable to milk and milk products.
英文名称Food products - Determination of the total nitrogen content by combustion according to the Dumas principle and calculation of the crude protein content — Part 1: Oilseeds and animal feeding stuffs
