适用范围:
3.1 The procedures covered in this guide are general and provide the user with information helpful for writing sampling plans, safety plans, labeling and shipping procedures, chain-of-custody procedures, general sampling procedures, general cleaning procedures, and general preservation procedures.3.2 For purposes of this guide, it is assumed that the user has knowledge of the waste being sampled and the possible safety hazards.3.3 This guide is not to be used when sampling sites or wastes when safety hazards are unknown. In such cases, the user shall use other more appropriate procedures.1.1 This guide provides information for formulating and planning the many aspects of waste sampling (see 1.2) that are common to most waste sampling situations.1.2 The aspects of sampling that this guide addresses are as follows: SectionSafety plans 4Sampling plans 5Quality assurance considerations 6General sampling considerations 7Preservation and containerization 8Cleaning equipment 9Packaging, labeling, and shipping procedures 10Chain-of-custody procedure 111.3 This guide does not provide comprehensive sampling procedures for these aspects, nor does it serve as a guide to any specific application. It is the responsibility of the user to ensure that the procedures used are proper and adequate.1.4 Units—The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that 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. For more specific precautionary statements see 3.2, 3.3, and Section 4.1.6 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.
