This is Part 19 of GB/T 2910. Textiles — Quantitative Chemical Analysis — Part 19: Mixtures of Cellulose Fibres and Asbestos (Method by Heating) SAFETY PRECAUTIONS — When cutting yarn or fabric containing asbestos, normal safety precautions shall be taken to avoid inhalation of asbestos dust. 1 Scope This part of GB/T 2910 specifies a method, by heating, to determine the percentage of cellulosic fibre in textiles made of binary mixtures of -- cotton or regenerated cellulose and -- chrysotile and crocidolite asbestos. This method may be applicable to other types of asbestos, subject to agreement between the interested parties.
