Download or read book Proposed ASTM Method for the Determination of Asbestos in Air by TEM and Information on Interfering Fibers written by W. Randy Boltin and published by . This book was released on 1999 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The draft of the ASTM Test Method for air entitled: "Airborne Asbestos Concentration in Ambient and Indoor Atmospheres as Determined by Transmission Electron Microscopy Direct Transfer (TEM)" (ASTM Z7077Z) is an adaptation of the International Standard, ISO 10312. It is currently undergoing a revision in regard to the reporting of confidence intervals for analysis results. The method differs considerably from the AHERA air clearance analysis method in that the counting rules provide a fairly complete characterization of the sizes of structures and structural components of asbestos-containing particles in the air. With the information derived from a full analysis, it is possible to determine the total asbestos structure count, the total fiber count, the PCM equivalent fiber count, the AHERA equivalent structure count and a number of other count values based on specific criteria. Examples of nonasbestos fibers which might interfere with the analysis (antigorite, palygorskite, halloysite, hornblende, sepiolite and vermiculite scrolls) are also included.

Download or read book International Organization for Standardization Methods for Determination of Asbestos in Air written by Eric J. Chatfield and published by . This book was released on 1999 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two International Standards for measurement of asbestos in air by transmission electron microscopy (TEM) have been approved. A key feature of the ISO TEM methods is the ability, from a single examination, to derive fiber concentrations for comparison with all known legislated control limits, and to provide a coded description of the size and nature of each asbestos structure to assist in the interpretation of health effects. The direct-transfer TEM method for determination of asbestos in air (ISO 10312) was published as an International Standard in May 1995. Voting on an indirect-transfer TEM method (ISO 13794) has been completed, and the final draft has been submitted for publication. A method for determination of the concentration of inorganic fibers in air, based on scanning electron microscopy (SEM), has recently been submitted for voting as a Draft International Standard, currently designated as ISO/DIS 14966. A new working group, ISO/TC 146/SC 6/WG4, was formed in late 1996, to develop International Standards for sampling strategy for determination of asbestos and other mineral fibers in building atmospheres.

Download or read book Applications of the ASTM Asbestos in Dust Method D5755 written by James R. Millette and published by . This book was released on 1999 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The American Society for Testing and Materials Standard Method D5755 (Asbestos Count Dust Method) is used by a variety of industrial hygienists, architects, engineers, laboratories and environmental consultants in their assessments of asbestos fibers in a building. Dust sampling provides information that cannot be obtained with bulk sampling or air sampling. 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. In some cases, the asbestos values in the dust have been compared to the values determined in the dust from other areas deemed to be non-contaminated. In other situations, the levels of 1,000 str/cm2 or 10,000 str/cm2 have been used in decision making.
