Ambient air. Determination of asbestos fibres. Indirect-transfer transmission electron microscopy method1 Scope This document specifies a reference method using transmission electron microscopy for the determination of airborne asbestosfibres and structures in in a wide range of ambient air situations, including the interior atmospheres of buildings, and for a detailed evaluation for asbestosstructures in any atmosphere. The specimen preparation procedure incorporates ashing and dispersion of the collected particulate, so that all asbestos is measured,
