1.1 本试验方法包括使用宽试样、湿试样和干试样测定土工织物的工厂和现场接缝强度。 1.2 本试验方法不涉及接缝技术的长期性能。该试验方法将提供数据，以表明每个特定土工织物和接缝组件结构可实现的短期接缝强度。为了评估接缝技术的长期性能，可以使用实践 D6389 ，使用本试验方法确定初始、短期宽幅拉伸强度的预期强度降低（试验方法 D4595 )结果。 1.3 以SI单位或英寸-磅单位表示的数值应单独视为标准值。每个系统中所述的值不一定是精确的等价物； 因此，为了确保符合标准，每个系统应独立使用，两个系统的值不得组合使用。 1.4 本标准并不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建立适当的安全、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 如测试方法中所述 D4595 ，狭窄的土工织物试样表明，在应力作用下，标距区域有收缩（颈部向下）的趋势。在强度测试期间，较宽的试样将使接缝中的这种现象最小化。在该测试方法中获得的结果可以更准确地与现场预期的接缝强度值相关联。 5.2 该测试方法可用于在工厂或现场测量土工布的接缝强度，也可用于土工布商业装运的验收测试。 5.3 该试验方法可用于帮助确定待评估土工织物的接缝设计工程，以及比较湿处理试样和干试样结果。 5.4 本试验方法不用于解决接缝的长期性能，也不用于解决其任何部件（如螺纹或粘合剂）的长期性能。然而，它可以用作监测暴露于任何特定暴露的接缝行为的指标值，例如，作为评估其长期性能的一部分。

1.1 This test method covers the determination of the factory and field seam strength of geotextiles, using a wide specimen and wet and dry specimens. 1.2 The long-term performance of a seaming technique is not addressed by this test method. This test method will provide data to indicate the short-term seam strength that can be achieved for each particular geotextile and seam assembly construction. To assess the long-term performance of a seaming technique, it is possible to use Practice D6389 , using this test method to determine the anticipated strength reduction in the initial, short-term wide-width tensile strength (Test Method D4595 ) results. 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 As explained in Test Method D4595 , narrow geotextile specimens demonstrate the tendency to contract (neck down) in the gauge area when under stress. The wider width specimen will minimize this phenomenon in seams during strength testing. The results achieved in this test method can more accurately correlate to the seam strength values anticipated in the field. 5.2 This test method can be used to measure the seam strength of geotextiles from the factory or field, and may also be used for acceptance testing of commercial shipments of geotextiles. 5.3 This test method can be used to help determine seam design engineering for the geotextiles being evaluated, as well as comparing wet-conditioned specimens with dry specimen results. 5.4 This test method is not intended to address long-term performance of a seam, nor any of its components such as the thread or the adhesive. However, it can be used as an index value to monitor the behavior of a seam exposed to any particular exposure, in example as part of an effort to assess its long-term performance.
