1.1 本指南涵盖了土工合成粘土衬垫（GCL）材料的验收试验要求指南，描述了试验类型、试验方法和建议验证。 1.2 本指南旨在帮助采购商、安装商、承包商、业主、运营商、设计师和机构建立产品验收测试和验证的最低工作水平。这旨在确保提供的GCL辊符合公认的材料规范。 1.3 以国际单位或英寸-磅单位表示的数值应单独视为标准值。每个系统中所述的值不一定精确相等；因此，为了确保符合标准，每个系统应独立于另一个系统使用，并且两个系统的值不应合并。 1.4 本指南提供了有组织的信息集合或一系列选项，并不建议具体的行动方案。本指南不能取代教育或经验，应与专业判断结合使用。并非本指南的所有方面都适用于所有情况。本指南并不代表或取代必须用来判断特定专业服务是否充分的谨慎标准，也不应在应用本指南时不考虑项目的许多独特方面。本指南标题中的“标准”一词仅表示该指南已通过ASTM共识程序获得批准。 1.5 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者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。

1.1 This guide covers guidelines for the acceptance testing requirements for geosynthetic clay liner (GCL) materials, describing types of tests, test methods, and recommended verifications. 1.2 This guide is intended to aid purchasers, installers, contractors, owners, operators, designers, and agencies in establishing a minimum level of effort for product acceptance testing and verification. This is intended to ensure that the supplied GCL rolls meet accepted material specifications. 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 1.4 This guide offers an organized collection of information or a series of options and does not recommend a specific course of action. This guide cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this guide may be applicable in all circumstances. This guide is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this guide be applied without consideration of a project's many unique aspects. The word “Standard” in the title of this guide means only that the guide has been approved through the ASTM consensus process. 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.
