Construction products: Assessment of release of dangerous substances - Sampling and quantitative determination of asbestos in construction products

Scope

This document summarizes methods for sampling, sample preparation and identification of asbestos in construction products. This document specifies appropriate sample preparation procedures for the quantitative analysis of the asbestos mass fraction in natural, manufactured or recycled large mineral aggregates and construction products of fine mineral particle size materials. This document describes the identification of asbestos by polarized light microscopy (PLM) and dispersion staining, scanning electron microscopy (SEM) with energy dispersive X-ray analysis or transmission electron microscopy (TEM) with energy dispersive X-ray and electron diffraction analysis.
NOTE This document is intended for microscopists familiar with polarized light, transmission electron- and scanning electron microscopy methods and the other analytical techniques specified (see ISO 10312, ISO 13794, ISO 14966, [McCrone et al., 1984], [Su et al., 1995]). It is not the intention of this document to provide instructions on basic analytical techniques.
