(Practice)Standard Practice for Collection of Settled Dust Samples Using Dry Wipe Sampling Methods for Subsequent Determination of Beryllium and Compounds
Standard Practice for Collection of Settled Dust Samples Using Dry Wipe Sampling Methods for Subsequent Determination of Beryllium and Compounds
SIGNIFICANCE AND USE
This practice is intended for the collection of settled dust samples for the subsequent measurement of beryllium and compounds. The practice is meant for use in the collection of settled dust samples that are of interest in clearance, hazard evaluation, risk assessment, and other purposes.
This practice is intended solely for the collection of settled dust samples from hard, relatively smooth nonporous surfaces that may be compromised by water or other wetting agents and that are therefore not suitable for wet wipe sampling using Practice D6966 or micro-vacuum sampling using Practice D7144. Use of this practice for any purpose other than the intended purpose is discouraged due to the limited collection efficiency and high variability of dry wipe sampling as compared to wetted wipe or micro-vacuum sampling .
This practice is less effective for collecting settled dust samples from surfaces with substantial texture such as rough concrete, brickwork, textured ceilings, and soft fibrous surfaces such as upholstery and carpeting. Micro-vacuum sampling using Practice D7144 may be more suitable for these surfaces.
SCOPE
1.1 This practice covers the collection of settled dust containing beryllium and/or beryllium compounds on surfaces using the dry wipe sampling method. These samples are collected in a manner that will permit subsequent extraction and determination of beryllium and compounds in the wipes using laboratory analysis techniques such as atomic spectrometry or fluorescence detection.
1.2 This practice is limited in its scope to applications where wetted wipe sampling (using Practice D6966) or vacuum sampling (using Practice D7144) is not physically feasible (for example, if the surface to be wiped would be compromised by use of wetted wipes).
1.3 This practice does not address the sampling design criteria (that is, sampling plan which includes the number and location of samples) that are used for clearance, hazard evaluation, risk assessment, and other purposes. To provide for valid conclusions, sufficient numbers of samples should be obtained as directed by a sampling plan. Additional guidance is provided in Guide D7659.
1.4 This practice contains notes that are explanatory and are not part of the mandatory requirements of this practice.
1.5 The values stated in SI units are to be regarded as standard.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
