1.1 本试验方法确定了土工合成粘土衬垫（GCL）抗拉强度的测量程序。本试验方法严格来说是一种指数试验方法，用于验证GCL的抗拉强度。本试验方法的结果不应被视为土工合成材料在现场应用中的实际或长期性能指标。 1.2 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值可能不是精确的等效值； 因此，每个系统应相互独立使用。将两个系统的值合并可能会导致不符合标准。 1.3 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。 1.4 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 该测试方法可用于GCL商业装运的验收测试，但由于实验室间精度信息不完整，建议谨慎。按照中的指示进行比较测试 5.1.1 可能是可取的。 5.1.1 如果使用本试验方法验收货物时，由于报告的试验结果不同而引起争议，买方和供应商应进行比较试验，以确定是否存在统计偏差。 双方应从相关材料批次中抽取一组尽可能均匀的试样。 5.2 根据GCL的结构，可能需要对夹紧技术进行一些修改。如果获得了具有代表性的抗拉强度，则可根据个人实验室的要求修改试样夹持。在任何情况下，第节中描述的程序 10 必须保持获得抗拉强度的本试验方法的有效性。 5.3 本测试方法适用于测试收到的GCL。它与恒速拉伸式张力装置一起使用。

1.1 This test method establishes the procedures for the measurement of tensile strength of a geosynthetic clay liner (GCL). This test method is strictly an index test method to be used to verify the tensile strength of GCLs. Results from this test method should not be considered as an indication of actual or long-term performance of the geosynthetic(s) in field applications. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 1.3 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. 1.4 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 This test method may be used for the acceptance testing of commercial shipments of GCLs, but caution is advised since information about between-laboratory precision is incomplete. Comparative tests as directed in 5.1.1 may be advisable. 5.1.1 In cases of a dispute arising from differences in reported test results when using this test method for acceptance of shipments, the purchaser and the supplier should conduct comparative tests to determine if there is a statistical bias. The two parties should take a group of test samples that are as homogeneous as possible and which are from the lot of material in question. 5.2 Some modification of clamping techniques may be necessary for a given GCL, depending upon its structure. Specimen clamping may be modified as required at the discretion of the individual laboratory, provided a representative tensile strength is obtained. In any event, the procedure described in Section 10 of this test method for obtaining tensile strength must be maintained. 5.3 This test method is applicable for testing GCLs as received. It is used with a constant rate of extension type tension apparatus.
