1.1本指南提供了关于提供水采样和分析服务的实验室的一致良好实验室实践的信息。作为共识标准，这些是所有实验室在建立其良好实验室实践时应考虑的最低标准。 1.2本指南旨在供从事水采样和分析的实验室组织的选择、操作或控制负责人使用。 1.3本指南介绍了影响所生成数据有用性的组织、设施、资源和操作的特点。 1.4本指南介绍了中所述特征的选择和控制标准，并提出了纠正不可接受性能的建议。 1.5本指南描述了与国际标准化组织（ISO）9000系列标准和指南25完全一致的方法和实践- 1990 () . 1.6以英寸-磅为单位的数值应视为标准值。括号中给出的值仅供参考。 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和健康实践，并确定监管限制的适用性。 ====意义和用途====== 水的成分和特性数据经常用于评估人类和环境的健康和安全。 此外，此类数据经常用于过程控制或确定是否符合对水的可接受成分和特性进行限制的监管法规。 进行水采样并生成分析数据的实验室，以及负责选择实验室进行水质研究的人员，需要使用经协商一致制定的标准、指南和建议，并在进行选择时得到广泛接受。 实验室证明和记录对组织、设施、资源和操作进行了明智的选择和控制，这将提高所生成数据的可信度，并促进其接受。

1.1 This guide provides information on consensus good laboratory practices for laboratories that provide services in the sampling and analysis of water. As consensus standards, these are the minimum criteria that all laboratories should consider in establishing their good laboratory practices. 1.2 This guide is designed to be used by those responsible for the selection, operation, or control of laboratory organizations engaged in sampling and analysis of water. 1.3 This guide presents features of organization, facilities, resources, and operations which affect the usefulness of the data generated. 1.4 This guide presents criteria for selection and control of the features described in and also makes recommendations for the correction of unacceptable performance. 1.5 This guide describes methodology and practices intended to be completely consistent with the International Organization for Standardization (ISO) 9000 series of standards and Guide 25 - 1990 () . 1.6 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. 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. ====== Significance And Use ====== Data on the composition and characteristics of water are frequently used to evaluate the health and safety to humans and the environment. Moreover, such data are frequently used for process control or to ascertain compliance with regulatory statutes that place limits on acceptable compositions and characteristics of waters. Laboratories that conduct water sampling and generate analytical data, and those persons who have the responsibility for selecting a laboratory to perform water quality studies, need to use criteria, guidelines, and recommendations that have been developed by consensus and are well accepted in making this selection. Demonstration and documentation by a laboratory that there was judicious selection and control of organization, facilities, resources, and operations will enhance the credibility of the data produced and promote its acceptance.
