ASTM D3614-07(2021)

5.1?Data on the composition and characteristics of environmental atmospheres, such as ambient or work space air, are frequently used to evaluate the health and safety of humans. Data on the composition of atmospheric deposition samples are often used for environmental impact assessment.

5.2?These data are frequently used to ascertain compliance with regulatory statutes that place limits on acceptable compositions and characteristics of these atmospheres.

5.3?Laboratories that produce environmental sampling and analysis data and those who have the responsibility of selecting a laboratory to perform air quality studies need to know what criteria, practices, and recommendations have been accepted by consensus within this field of endeavor.

5.4?Demonstration and documentation by a laboratory that there is judicious selection and control of organizational factors, facilities, resources, and operations enhance the reliability of the data produced and promote the acceptance of these data.

1.1?This guide covers criteria to be used by those responsible for the selection, evaluation, operation, and control of laboratory organizations engaged in sampling and analysis of environmental atmospheres, including ambient, work space, and source emissions, as well as atmospheric deposition samples. For details specific to stack gases, see Practice D7036, which covers administrative issues in full; several specifics in this guide regarding laboratory operations may yet be helpful and do not overlap with Practice D7036.

1.2?This guide presents features of organizations, facilities, resources, and operations which by their selection and control affect the reliability and credibility of the data generated.

1.3?This guide presents the criteria for the selection and control of the features listed in 1.2 so that acceptable performance may be attained and sustained. Also, this guide presents recommendations for the correction of unacceptable performance.

1.4?The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.

1.5?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.

1.6?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.
