Air quality - Bulk materials - Part 2: Quantitative determination of asbestos by gravimetric and microscopical methods
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:
This document primarily applies to samples in which asbestos has been identified at estimated mass fractions lower than approximately 5 % by sample mass. This document is also applicable to samples that can contain asbestos at low mass fractions incorporated into matrix material such that microscopical examination of the untreated sample is either not possible or unreliable.
