ASTM D6552 - 06(2011) standard practice for controlling and characterizing errors in weighing collected aerosols

The weighing of collected aerosol is one of the most common and purportedly simple analytical procedures in both occupational and environmental atmospheric monitoring (for example, Test Method D4532 or D4096). Problems with measurement accuracy occur when the amount of material collected is small, owing both to balance inaccuracy and variation in the weight of that part of the sampling medium ...

ASTM D3268 - 91(2011) standard test method for separation and collection of particulate and gaseous fluorides in the atmosphere (Sodium bicarbonate-coated glass tube and particulate filter method)

The sodium bicarbonate coated tube filter method provides a means of separating and collecting atmospheric gaseous fluoride and particulate fluoride samples. Since the samples are collected on the dry tube and filter, the fluoride may be eluted with a small volume of eluant (see Section 10 for specific instructions on fluoride elution). Elution into a small volume and the sensitivity of the ...

ASTM D6058 - 96(2011) standard practice for determining concentration of airborne single-crystal ceramic whiskers in the workplace environment

The SCCW may be present in the workplace atmosphere where these materials are manufactured, processed, transported, or used. The test methods discussed in this practice can be used to provide guidance when monitoring airborne concentrations of SCCW in these environments. Because of their visibility limitations, a significant fraction of the very small thin fibers that are present in some samples ...

ASTM D1357 - 95(2011) standard practice for planning the sampling of the ambient atmosphere

Since the analysis of the atmosphere is influenced by phenomena in which all factors except the method of sampling and analytical procedure are beyond the control of the investigator, statistical consideration must be given to determine the adequacy of the number of samples obtained, the length of time that the sampling program is carried out, and the number of sites sampled. The purpose of the ...

ASTM D6057 - 96(2011) standard test method for determining concentration of airborne single-crystal ceramic whiskers in the workplace environment by phase contrast microscopy

The SCCW may be present in the workplace atmosphere where these materials are manufactured, processed, transported, or used. This test method can be used to monitor airborne concentrations of fibers in these environments. It may be employed as part of a personal or area monitoring strategy. This test method is based on dimensional considerations only. As such, it does not provide a positive ...
