1.1 该试验方法包括测量增强土工膜层（如内部增强土工薄膜和涂层织物）之间的粘合强度（180°剥离）。 1.2 本试验方法不用于确定土工膜接缝的强度或土工复合材料组件（如与土工膜粘合的无纺土工布或与排水芯粘合的土工布）的层间粘合强度。 1.3 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.4 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。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 5.1 该方法是一种指数测试，用于测量分离加固土工膜各层所需的力。附着力的可接受值因不同类型的产品而异。然而，对于特定类型的产品，生产商和消费者可以确定并同意帘布层附着力的最小值，双方都可以进行监测，以确保符合商定的值。 5.2 争议- 如果在使用这种测试方法进行商业货物的验收测试时，由于报告的测试结果存在差异而引起争议，买方和供应商应进行比较测试，以确定其实验室之间是否存在统计差异。建议提供适当的统计协助来调查这种差异。至少，双方应采取一组试样，这些试样来自与所讨论类型相同的材料批次，并且尽可能均匀。 然后，应将试样以相等数量随机分配到每个实验室进行测试。两个实验室的平均结果应使用Student’s进行比较 吨 -测试未配对的数据和双方在测试开始前选择的可接受的概率水平。如果发现差异，必须找到并纠正其原因，或者买方和供应商必须同意根据已知差异解释未来的测试结果。

1.1 This test method covers the measurement of the adhesion strength (180° peel) between plies of reinforced geomembranes such as internally reinforced geomembranes and coated fabrics. 1.2 This test method is not intended for determining the strength of geomembrane seams or for determining the ply adhesion strength of geocomposite components (such as nonwoven geotextile bonded to geomembrane, or geotextile bonded to drainage core). 1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. 1.4 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. 1.5 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 method is an index test and measures the force required to separate individual plies of a reinforced geomembrane. The acceptable value of adhesion will vary for different types of products. However, for a particular type of product, minimum values of ply adhesion can be determined and agreed to by producer and consumer, and both can monitor to ensure compliance with the agreed-upon value. 5.2 Disputes— In case of a dispute arising from differences in reported test results when using this test method for acceptance testing of commercial shipments, the purchaser and the supplier should conduct comparative tests to determine if there is a statistical difference between their laboratories. Competent statistical assistance is recommended for the investigation of this difference. At a minimum, the two parties should take a group of test specimens which are from the same lot of material as those type in question and which are as homogeneous as possible. The test specimens should then be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using Student's t -test for unpaired data and an acceptable probability level chosen by the two parties before the testing began. If a difference is found, either its cause must be found and corrected, or the purchaser and the supplier must agree to interpret future test results in the light of the known difference.
