1.1 本试验方法包括用于测定大多数纺织织物的断裂力和伸长率的散条和切割条试验程序。规定了湿法试验。 1.1.1 剥离条测试适用于机织物，而切割条测试适用于非织造织物、毡制织物和 浸渍 或涂层织物。 1.2 该测试方法不推荐用于针织物或其他具有高拉伸（超过11%）的纺织织物。 附注1: 关于使用抓取试验和改进的抓取试验程序测定纺织品的断裂力和伸长率，请参阅试验方法 D5034 . 附注2: 对于使用条带试验测定某些特定类型织物的断裂力和伸长率，请参阅规范 D579/D579M 和 D580/D580M . 1.3 该测试方法显示了英寸-磅单位和国际单位制单位的值。英寸-磅单位是美国使用的习惯单位的技术正确名称。国际单位制是公制单位制的技术正确名称，称为国际单位制。以可接受的公制单位或其他单位表示的值应单独视为标准值。每个系统中表示的值可能不完全等同；因此，每个系统必须独立使用，而不以任何方式组合。 1.4 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。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 本试验方法中的散条试验被认为对于机织纺织品商业装运的验收试验是令人满意的，因为该方法已在行业中广泛用于验收试验。对于毡制或非织造织物的切割条测试也是如此。 5.1.1 如果两个（或多个）实验室报告的检测结果之间存在具有实际意义的差异，应使用合格的统计学辅助进行比较试验，以确定它们之间是否存在统计学偏倚。至少，使用尽可能同质的样品进行比较试验，这些样品取自与初始试验期间产生不同结果的样品相同批次的材料，并以相等的数量随机分配给每个实验室。应使用不成对数据的统计检验来比较相关实验室的检验结果，这是在检验系列之前选择的概率水平。如果发现偏差，要么必须找到并纠正其原因，要么必须根据已知偏差调整该材料的未来测试结果。 5.2 这种方法不推荐用于针织物，因为它们的弹性很高。 5.3 对于具有超过200N/cm(1140lbf/in.)宽度的强度的任何织物，可能需要对技术进行一些修改。必要时使用强力织物或玻璃纤维制成的织物时，应采取特殊的预防措施（见规范 D579/D579M )，以防止它们在夹具中滑动或由于被夹具夹持而损坏。 5.4 所有程序均适用于测试经调理或湿织物。 5.5 不建议比较不同原理的拉伸试验机的结果。当使用不同类型的机器进行比较测试时，20s±3s的恒定中断时间是产生数据的既定方式。即使这样，数据也可能有很大差异。 5.6 尽管在这些方法中，恒定延伸率拉伸试验机是优选的，但在发生争议的情况下，除非买方和供应商之间有相反的协议，恒定-使用断裂时间（20s±3s）。 5.7 分离带程序适用于确定断裂特定宽度织物所需的力。织造织物的断裂力信息对于比较织物中纱线的有效强度与相同数量的未织造的相同纱线的组合强度特别有用。对于样品宽度上纱线少于20根的织物，不建议使用该程序。如果使用25毫米（1英寸）条带无法获得每个样品20根纱线的宽度，则应使用50毫米（2英寸）条带。一般来说，50毫米（2英寸）样品的观察力不是25毫米（1英寸）样品观察力的两倍，结果应报告为在50毫米（2英寸）样品上观察到的结果。）条带，无需数学调整至25毫米（1英寸）。如果织物不容易散开，使用切割带或抓取程序。 5.8 切条程序适用于高度填充的织物、不易散开的机织物、毡制织物和非织造织物。对于可能散开的织物，不建议使用此程序，因为边缘的纱线在测试过程中容易散开。中讨论的关于机织样品中最小纱线数量的建议 5.7 对于散开的带材，同样适用于切割带材。

1.1 This test method covers raveled strip and cut strip test procedures for determining the breaking force and elongation of most textile fabrics. Provision is made for wet testing. 1.1.1 The raveled strip test is applicable to woven fabrics while the cut strip test is applicable to nonwoven fabrics, felted fabrics, and dipped or coated fabrics. 1.2 This test method is not recommended for knitted fabrics or for other textile fabrics which have high stretch (more than 11 %). Note 1: For the determination of the breaking force and elongation of textile fabrics using the grab test and modified grab test procedures, refer to Test Method D5034 . Note 2: For determination of the breaking force and elongation of some specific types of fabrics which use the strip test, refer to Specifications D579/D579M and D580/D580M . 1.3 This test method shows the values in both inch-pound units and SI units. Inch-pound units is the technically correct name for the customary units used in the United States. SI units is the technically correct name for the system of metric units known as the International System of Units. The values stated in either acceptable metric units or in other units shall be regarded separately as standard. The values expressed in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining in any way. 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 raveled strip test in this test method is considered satisfactory for acceptance testing of commercial shipments of woven textile fabrics because the method has been used extensively in the trade for acceptance testing. The same is true for the cut strip test for felted or nonwoven textile fabrics. 5.1.1 If there are differences of practical significance between reported test results for two laboratories (or more), comparative test should be performed to determine if there is a statistical bias between them, using competent statistical assistance. At a minimum, use the samples for such a comparative test that are as homogeneous as possible, drawn from the same lot of material as the samples that resulted in disparate results during initial testing and randomly assigned in equal numbers to each laboratory. The test results from the laboratories involved should be compared using a statistical test for unpaired data, a probability level chosen prior to the testing series. If bias is found, either its cause must be found and corrected, or future test results for that material must be adjusted in consideration of the known bias. 5.2 The method is not recommended for knitted fabrics because of their high stretch. 5.3 Some modification of the techniques may be necessary for any fabric having a strength in excess of 200 N/cm (1140 lbf/in.) width. Special precautionary measures are provided for use when necessary with strong fabrics, or fabrics made from glass fibers (see Specification D579/D579M ), to prevent them from slipping in the clamps or being damaged as a result of being gripped in the clamps. 5.4 All of the procedures are applicable for testing fabrics either conditioned or wet. 5.5 Comparison of results from tensile testing machines operating on different principles is not recommended. When different types of machines are used for comparison testing, constant time-to-break at 20 s ± 3 s is the established way of producing data. Even then the data may differ significantly. 5.6 Although a constant-rate-of-extension tensile testing machine is preferred in these methods, in cases of dispute, unless there is agreement to the contrary between the purchaser and supplier, a constant-time-to-break (20 s ± 3 s) is to be used. 5.7 The raveled strip procedure is applicable to the determination of the force required to break a specific width of fabric. The breaking force information on woven fabrics is particularly useful for comparison of the effective strength of the yarns in the fabric with the combined strength of an equal number of the same yarns which are not woven. The procedure is not recommended for fabrics having fewer than 20 yarns across the width of the specimen. If a 20-yarns-per-specimen width cannot be obtained with a 25-mm (1-in.) strip, a 50-mm (2-in.) strip should be used. In general, the observed force for a 50-mm (2-in.) specimen is not double the observed force for a 25-mm (1-in.) specimen and the results should be reported as observed on a 50-mm (2-in.) strip without mathematical adjustment to 25 mm (1 in.). If a fabric cannot be raveled readily, use either a cut strip or grab procedure. 5.8 The cut strip procedure is applicable to heavily fulled fabrics, woven fabrics that cannot be readily raveled, felted fabrics and nonwoven fabrics. This procedure is not recommended for fabrics which can be raveled because the yarns at the edges tend to unravel during testing. The recommendation regarding the minimum number of yarns in a woven specimen discussed in 5.7 for raveled strips applies equally to cut strips.
