Overview
This document has been prepared by German standardization committee NA 005-53 FBR "Fachbereichsbeirat KOA 03 - Hygiene, Gesundheit und Umweltschutz (SpA zu CEN/TC 351, CEN/TC 351/WG 3, CEN/TC 351/WG 4 und CEN/TC 351/WG 5)" ("Steering Committee of Section KOA 03 - Hygiene, Health and the Environment (National Mirror Committee for CEN/TC 351, CEN/TC 351/WG 3, CEN/TC 351/WG 4 and CEN/TC 351/WG 5)") at DIN Standards Committee Building and Civil Engineering (NABau). 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.
