Three commercially available vacuum samplers (also known as microvacuum samplers or microvacs) were examined for compliance with the Standard ASTM Methods for asbestos in settled dust. The American Society for Testing and Materials (ASTM) Standard Test Method (D5755-95) for Microvacuum Sampling and Indirect Analysis of Dust by Transmission Electron Microscopy for Asbestos Structure Number Concentration and the similar Method (D5756-95) for mass require that a sample be collected by vacuuming a known surface area with a standard 25 or 37 mm air sampling cassette using a plastic tube that is attached to the inlet orifice which acts as a nozzle.
