2017年8月16日 · Standard Test Method for Microvacuum Sampling and Indirect Analysis of Dust by Transmission Electron Microscopy for Asbestos Structure Number Concentrations.

There are two commonly used ASTM methods available for sampling settled dust for asbestos analysis: ASTM D5755 (Micro-vacuum Method) and ASTM D6480 (Wipe Method). These methods are used to sample and analyze settled dust from a given area. Notes:

2022年12月11日 · This standard is issued under the Þxed designation D5755; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.

It is intended to disperse aggregated asbestos into fundamental fibrils, fiber bundles, clusters, or matrices that can be more accurately quantified by transmission electron microscopy.

1999年1月1日 · Information obtained using Method D5755 has been used to assess the extent of contamination resulting from an accidental or unauthorized disturbance of asbestos containing material and to assist in making decisions about cleaning a potentially contaminated area.

This standard is issued under the fixed designation D5755; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.
