[Here, modified polyacrylonitrile fibers refer to those that dissolve when placed in concentrated sulfuric acid (ρ = 1.84 g/mL). When preliminary tests show that chlorinated fibers are not completely soluble in dimethylformamide or carbon disulfide/acetone azeotropic mixtures, this method can be used instead of GB/T 2910.12 and GB/T 2910.13. 2 Normative references The provisions of the following documents become the provisions of this Part through reference to this Part of GB/T 2910.For dated references, all subsequent amendments (excluding errata) or revisions are not applicable to this Part. However, parties reaching an agreement based on this Part are encouraged to study whether the latest versions of these documents can be used. For undated references, the latest versions apply to this Part. GB/T 2910.1 Textiles - Quantitative chemical analysis - Part 1.General principles of testing (GB/T 2910.1-2009, ISO 1833-1.2006, IDT) 3 Principle Use concentrated sulfuric acid (ρ = 1.84 g/mL) reagent to dissolve and remove non- ......
