1.1 This practice covers the collection of settled dust containing beryllium and beryllium compounds on surfaces using the dry wipe sampling method, or both. 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 ) or vacuum sampling (using Practice ) 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 .
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. No other units of measurement are included in this 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
