1.1 本试验方法包括使用分体式鼓型试样夹测定织物织带、胶带和编织材料的断裂强度和伸长率。 1.2 该试验方法仅限于最大宽度为90 mm（3.5 in.）且最大断裂强度不超过89000 N（20000 lb）的材料。 1.3 以国际单位制或美国习惯单位表示的数值应单独视为标准。在正文中，括号中给出了美国习惯单位。每个系统中规定的数值并不完全相等；因此，每个系统应独立使用。 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。 1.5 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 此测试方法可用于商业装运的验收测试，但应谨慎进行比较，因为实验室间精度的估计不完整。 5.1.1 如果两个实验室（或多个实验室）报告的测试结果之间存在实际意义上的差异，则应使用主管的统计协助进行比较测试，以确定它们之间是否存在统计偏差。 作为最低要求，使用尽可能均匀的样本进行此类比较测试，这些样本与在初始测试期间产生不同结果的样本来自同一批次的材料，并以相同数量随机分配给每个实验室。应使用未配对数据的统计测试，在测试系列之前选择概率水平，对相关实验室的测试结果进行比较。如果发现偏差，必须找到并纠正其原因，或者必须在考虑已知偏差的情况下调整该材料的未来测试结果。 5.2 伸长率是指纤维吸收能量的能力。纺织材料的伸长率必须足够大，以承受加工和最终使用过程中所经历的应变，并吸收反复施加的力的能量。

1.1 This test method covers the determination of the breaking strength and elongation of textile webbing, tape and braided materials using a split-drum type specimen clamp. 1.2 This test method is limited to materials with a maximum width of 90 mm (3.5 in.) and a maximum breaking strength of no more than 89000 N (20000 lb). 1.3 The values stated in either SI units or U.S. Customary units are to be regarded separately as standard. Within the text, the U.S. Customary units are given in parentheses. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. 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 This test method can be used for acceptance testing of commercial shipments but comparisons should be made with caution because estimates of between-laboratory precision are incomplete. 5.1.1 If there are differences of practical significance between reported test results for two laboratories (or more), comparative tests should be performed to determine if there is a statistical bias between them, using competent statistical assistance. As a minimum, use samples for such comparative tests 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, at 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 Elongation is an indication of the ability of a fiber to absorb energy. The elongation of textile materials must be great enough to withstand strains experienced in processing and end use, and to absorb the energies of applied forces repeatedly.
