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.
