1.1 本试验方法涵盖了确定轧制侵蚀控制产品（RECP）拉伸性能的带材试验程序。 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 本标准不适用于复合材料制成的RECP，其中提供钢筋的部件无法按照本文所述的程序进行抗拉强度测试。在这种情况下，应使用最适合该材料的既定ASTM试验方法。 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 本试验方法中的带材试验对于轧制侵蚀控制产品的商业装运验收试验（即符合规范）而言是令人满意的，因为该方法已在验收试验行业中广泛使用。 5.1.1 如果在使用本测试方法进行商业装运验收测试时，由于报告测试值的差异而产生分歧，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。至少，双方应从大量相关类型的材料中选取一组尽可能均匀的试样。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学生的 t -测试未配对数据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，或者买方和供应商必须同意根据已知偏差解释未来结果。

1.1 This test method covers strip test procedures for determining the tensile properties of rolled erosion control products (RECPs). 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information purposes only. 1.3 This standard does not apply to RECPs made of composite materials where the component providing the reinforcement cannot be tested for tensile strength with the procedure herein described. In this case, the established ASTM testing method which is most appropriate for that material shall be used instead. 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 strip test in this test method is considered satisfactory for acceptance testing (that is, conformance to a specification) of commercial shipments of rolled erosion control products, since the method has been used extensively in the trade for acceptance testing. 5.1.1 In case of disagreement arising from differences in reported test values 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 investigation of bias. At a minimum, the two parties should take a group of test specimens which are as homogeneous as possible and are from a lot of material of the type in question. 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 testing is begun. If bias is found, either its cause must be found and corrected, or the purchaser and the supplier must agree to interpret future results in the light of the known bias.
