1.1 本指南涵盖了负责选择、评估、操作和控制参与环境大气（包括环境、工作空间和源排放以及大气沉积样品）采样和分析的实验室组织的标准。有关烟囱气体的详细信息，请参阅实践 D7036 ，全面涵盖行政问题；本指南中有关实验室操作的几个细节可能仍有帮助，并且不会与实践重叠 D7036 . 1.2 本指南介绍了组织、设施、资源和操作的特征，这些特征通过其选择和控制影响生成数据的可靠性和可信度。 1.3 本指南介绍了中所列功能的选择和控制标准 1.2 从而达到并保持可接受的性能。此外，本指南还提出了纠正不可接受性能的建议。 1.4 以国际单位制表示的数值应视为标准值。 国际单位制后括号中给出的值仅供参考，不被视为标准值。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 环境空气（如环境空气或工作空间空气）的组成和特征数据经常用于评估人类的健康和安全。大气沉积样品的成分数据通常用于环境影响评估。 5.2 这些数据经常用于确定是否符合对这些大气的可接受成分和特性进行限制的监管法规。 5.3 产生环境采样和分析数据的实验室以及有责任选择实验室进行空气质量研究的实验室需要知道在这一领域内，哪些标准、实践和建议已被一致接受。 5.4 实验室证明和记录对组织因素、设施、资源和操作进行了明智的选择和控制，从而提高了所生成数据的可靠性，并促进了对这些数据的接受。

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. ====== Significance And Use ====== 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.
