Textiles - Quantitative chemical analysis - Part 19: Mixtures of cellulose fibres and asbestos (method by heating) (ISO 1833-19:2006)
This part of ISO 1833 specifies a method, by heating, to determine the percentage of cellulosic fibre in textiles made of binary mixtures of
- cotton or regenerated cellulose
- chrysotile and crocidolite asbestos.
This method may be applicable to other types of asbestos, subject to agreement between the interested parties.
NOTE This method differs in principle from the general method based on selective solubility set out in ISO 1833-1.
