Abstract

Specifies a method for the qualitative identification of asbestos in bulk samples using a number of steps, depending on the sample appearance and composition. Polarized light microscopy is described as the primary detection technique.

Scope

This Standard sets out a method for the qualitative identification of amosite, crocidolite and chrysotile in bulk samples by polarized light microscopy (PLM) and dispersion staining (DS) techniques. It does not cover the identification of airborne and water-borne asbestos.
The techniques used in this Standard ensure that -
(a) either homogeneous or non-homogenous matter can be analysed;
(b) fibres are able to be differentiated from the parent mineral;
(c) chrysotile, amosite and crocidolite asbestos fibres are able to be unequivocally identified; and
(d) the practical limit of detection can be determined as a part of the method validation.
