1 Scope This part of GB/T 2910 specifies a method, by determining the nitrogen content, to calculate the proportion of each component, after the removal of non-fibrous matter, in textiles made of binary mixtures of jute and animal fibres. The animal-fibre component may consist solely of hair or wool, or of any mixtures of the two. This part is not applicable to products in which dyestuffs or finishes contain nitrogen. Note: Because this method differs in principle from the general method based on selective solubility set out in GB/T 2910, it is given in a form that is complete in itself. 2 Normative References The following normative documents contain provisions which, through reference in this Part of GB/T 2910, constitute provisions of this Part. For dated reference, subsequent amendments (excluding corrigendum content) to, or revisions of, any of these publications do not apply. However, all parties coming to an agreement according to this Part are encouraged to study whether the latest editions of these documents are applicable. For undated references, the latest edition of the normative document referred to applies.
