This document specifies procedures for quantification of asbestos mass fractions below approximately 5 %, and for quantitative determination of asbestos in vermiculite, other industrial minerals and commercial products that incorporate these minerals.


This document is applicable to the quantitative analysis of:


a)       any material for which the estimate of asbestos mass fraction obtained using ISO 22262-1 is deemed to be of insufficient precision to reliably classify the regulatory status of the material (i.e. whether the material is subject to asbestos regulations in the particular jurisdiction) or for which it is considered necessary to obtain further evidence to demonstrate the absence of asbestos;


b)       resilient floor tiles, asphaltic materials, roofing felts and any other materials in which asbestos is embedded in an organic matrix;


c)        wall and ceiling plasters, with or without aggregate;
