1.1 本试验方法涵盖了测定所有草皮加固垫单位面积质量的指标。 1.2 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。 1.3 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。 1.4 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 该试验方法用于确定草皮加固垫是否符合单位面积质量的规范。此测试方法可用于质量控制，以确定试样的一致性。这种测量允许通过比较输送材料的单位面积质量和规定的单位面积重量来简单地控制输送材料。 5.2 本测试方法中的程序可用于商业装运的验收测试，但由于实验室之间的精度信息不完整，因此建议谨慎。根据 5.2.1 是可取的。 5.2.1 如果在使用本测试方法中的程序对商业货物进行验收测试时，由于报告的测试结果存在差异而引起争议，买方和制造商应进行比较测试，以确定其实验室之间是否存在统计偏差。建议为偏见调查提供适当的统计协助。至少，双方应采取一组尽可能均匀的试样，这些试样来自大量相关类型的材料。然后，应将试样以相等的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适当的学生的 吨 -测试和双方在测试开始前选择的可接受概率水平。如果发现偏差，必须找到并纠正其原因，或者买方和制造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 covers an index to the determination of mass per unit area of all turf reinforcement mats. 1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. 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 is used to determine if the turf reinforcement mat meets specifications for mass per unit area. This test method can be used for quality control to determine specimen conformance. This measurement allows for a simple control of the delivered material by a comparison of the mass per unit area of the delivered material and the specified mass per unit area. 5.2 The procedure in this test method may be used for acceptance testing of commercial shipments, but caution is advised since information about between-laboratory precision is incomplete. Comparative tests in accordance with 5.2.1 are advisable. 5.2.1 In case of a dispute arising from differences in reported test results when using the procedures in this test method for acceptance testing of commercial shipments, the purchaser and the manufacturer 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. At a minimum, the two parties should take a group of test specimens that are as homogeneous as possible and which are from a lot of material of the type in question. The test specimen should then be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using the appropriate Student’s t -test and an acceptable probability level chosen by the two parties before testing is begun. If a bias is found, either its cause must be found and corrected or the purchaser and the manufacturer must agree to interpret future test results in light of the known bias.
