1.1 本试验方法涵盖了草皮加固垫（TRM）在689 kPa[100 psi]下承受三个循环的载荷1分钟/次后的弹性或恢复。 1.2 本试验方法不提供TRM在可变法向压应力下的弹性值。本试验方法确定标称弹性。 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 弹性可用于控制许多TRM的质量。弹性可以表示TRM在暴露于制造、运输和安装过程中可能施加的应力后保持原始配置的能力。弹性通常并不表示现场表现。 5.2 TRM的弹性可能会因加载循环期间施加在试样上的压力而发生很大变化。为了最大限度地减少变化，本试验方法中指出了具体的样品尺寸和施加的压力，以确保所有结果具有可比性。 5.3 为了确定不同压力载荷对TRM最终厚度的影响，使用本试验方法。 5.4 该测试方法可用于TRM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。根据 5.4.1 可能是可取的。 5.4.1 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。 建议为调查偏差提供称职的统计协助。作为最低要求，双方应采取一组尽可能均匀的试样，这些试样由大量相关类型的材料制成。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学生的 t -开始测试未配对数据和双方选择的可接受概率水平。如果发现偏差，必须纠正其原因，或者买方和被发现并解释供应商未来的测试必须同意已知偏差。 注1: 用户应注意，材料的可压缩性、其回弹特性等也将受到TRM在运输和储存的辊子上卷起后的厚度的影响。

1.1 This test method covers the resiliency or recovery of turf reinforcement mats (TRMs) after they have been subjected to three cycles of loading at 689 kPa [100 psi] for 1 min/per cycle. 1.2 This test method does not provide resiliency values for TRMs under variable normal compressive stresses. This test method determines nominal resiliency. 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 Resiliency may be used to control the quality of many TRMs. Resiliency may be indicative of a TRM's ability to retain original configuration after exposure to the stresses which may be exerted during manufacture, shipping, and installation. Resiliency is not generally indicative of field performance. 5.2 The resiliency of TRMs may vary considerably depending on the pressure applied to the specimen during loading cycles. To minimize variation, specific sample size and applied pressure are indicated in this test method to ensure all results are comparable. 5.3 To determine the effect of different pressure loadings on the final thickness of TRMs, use this test method. 5.4 This test method may be used for acceptance testing of commercial shipments of TRMs, but caution is advised since information on between-laboratory precision is incomplete. Comparative tests in accordance with 5.4.1 may be advisable. 5.4.1 In a 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 bias between their laboratories. Competent statistical assistance is recommended for the investigation of bias. As a minimum, the two parties should take a group of test specimens that are as homogeneous as possible and that are formed from a lot of material of the type in question. The test specimens should 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 begun. If bias is found, either its cause must corrected, or the purchaser and be found and interpret future tests in supplier must agree to the light of the known bias. Note 1: The user should be aware that the compressibility of the materials, their rebound characteristics, and the like will also be affected by the thickness of the TRMs following the time when they are rolled up on rolls shipped and stored.
