1.1 本试验方法建立了评估草皮加固垫（TRM）在短期压缩载荷下变形的程序。本试验方法严格来说是一种指数试验方法，用于验证给定人造土工合成材料的抗压强度一致性。该试验方法的结果不应被视为TRM在现场应用中的实际或长期性能的指示。 1.2 由于这些TRM在现场经历了多向压缩载荷，因此该测试方法不会显示实际的现场性能，不应用于该特定目标。 结果评估还应认识到，土工合成材料短期单平面压缩行为的确定并不反映TRM的安装性能，因此，不应作为产品或性能规范的唯一方法。 1.3 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不一定是精确的等价物；因此，为确保符合本标准，每个系统应独立使用，且两个系统的值不得组合。 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。 1.5 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 TRMs的压缩行为测试旨在作为一项指标测试。预计压缩性能测试的结果将用于评估产品。分析结果也可用于比较表现出可检测压缩屈服点的材料的相对压缩屈服点。预计该测试将用于质量控制测试，以评估样品几何因素（例如厚度或材料）可能发生变化的批次内或批次之间的均匀性和一致性。 注1: 这是一个- TRM在一个平面内压缩载荷的尺寸试验。 5.1.1 可根据应力/应变关系评估TRM的压缩屈服点。许多材料表现出压缩变形，但可能没有表现出明显的压缩屈服点。 5.2 该试验方法可用于评估以恒定变形速率加载时，TRM在压应力下的短期应力/应变行为。 5.3 该测试方法可用于TRM商业装运的验收测试，但建议谨慎，因为实验室间测试不完整。 5.3.1 如果使用本测试方法进行商业装运验收测试时，由于报告测试结果的差异而产生争议，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偏差。 建议为偏差调查提供主管统计协助。作为最低要求，双方应从运往项目的材料中抽取一组试样。然后，应将试样以相同数量随机分配给每个实验室进行测试。两个实验室的平均结果应使用未配对数据的学生t检验和双方在测试开始前选择的可接受概率水平进行比较。如果发现偏差，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偏差解释未来的测试结果。

1.1 This test method establishes the procedures for evaluation of the deformations of a turf reinforcement mat (TRM) under short-term compressive loading. This test method is strictly an index test method to be used to verify the compressive strength consistency of a given manufactured geosynthetic. Results from this test method should not be considered as an indication of actual or long-term performance of the TRM in field applications. 1.2 Since these TRMs experience multidirectional compressive loadings in the field, this test method will not show actual field performance and should not be used for this specific objective. The evaluation of the results also should recognize that the determination of the short-term single plane compressive behavior of geosynthetics does not reflect the installed performance of TRMs and, therefore, should not be used as the only method of product or performance specification. 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 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 The compression behavior test for TRMs is intended to be an index test. It is anticipated that the results of the compression behavior test will be used to evaluate product. The results of the analyses also may be used to compare the relative compressive yield points of materials that exhibit a detectable compressive yield point. It is anticipated that this test will be used for quality control testing to evaluate uniformity and consistency within a lot or between lots where sample geometry factors, for example, thickness, or materials may have changed. Note 1: This is a one-dimensional test for compressive loading of a TRM in one plane. 5.1.1 The compressive yield point of TRMs may be evaluated from the stress/strain relationship. Many materials exhibit compressive deformation but may not show a distinct compressive yield point. 5.2 This test method can be used to evaluate the short-term stress/strain behavior of TRMs under compressive stress while loaded at a constant rate of deformation. 5.3 This test method may be used for acceptance testing of commercial shipments of TRMs but caution is advised because interlaboratory testing is incomplete. 5.3.1 In the 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 statistical bias between their laboratories. Competent statistical assistance is recommended for the investigations of bias. As a minimum, two parties should take a group of test specimens from material shipped to project. The test specimens then should be assigned randomly in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using the Student's t-test for unpaired data and an acceptable probability level chosen by the two parties before the testing is begun. If bias is found, either its cause must be found and corrected, or the purchaser and supplier must agree to interpret future test results in the light of the known bias.
