1.1 本指南涵盖了以下程序，用于测试设计用于绒线地板覆盖物制造的机织、针织和非织造背衬织物。程序按以下顺序显示: 部分 机织物的弓度和歪斜 8. 机织物和非织造织物的断裂力 15 机织物和非织造织物簇绒后的断裂力 16 可提取物质 9 机织物的织物计数 12 针织物的织物计数 13 机织物的长度 11 机织物单位面积质量（重量） 14 机织物的宽度 10 1.2 以英寸磅为单位的数值应视为标准。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。 1.3 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。 1.4 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 这些测试方法可用于商业装运的验收测试；然而，由于有关实验室间精度的信息不完整，因此建议谨慎行事。中所述的比较测试 5.1.1 可能是可取的。 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，则应进行比较测试，以使用有能力的统计辅助来确定它们之间是否存在统计偏差。 作为最低要求，使用尽可能均匀的测试样本进行此类比较测试，这些样本与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进行测试。实验室的测试结果应在测试系列之前选择的概率水平上，使用未配对数据的统计测试进行比较。如果发现偏差，则必须找到并纠正其原因，或者必须根据已知偏差调整该材料的未来测试结果。 5.2 这些测试方法有助于评估绒线地板覆盖物生产过程中的质量和成本控制。 5.3 特定性能和测试方法的重要性和用途在规定测试方法的适当章节中进行了讨论。

1.1 This guide covers the procedures listed as follows for testing woven, knitted and nonwoven backing fabrics designed for use in the manufacture of pile yarn floor coverings. The procedures appear in the following order: Section Bow and Skewness of Woven Fabrics 8 Breaking Force of Woven and Nonwoven Fabrics 15 Breaking Force After Tufting of Woven and Nonwoven Fabrics 16 Extractable Matter 9 Fabric Count of Woven Fabrics 12 Fabric Count of Knitted Fabrics 13 Length of Woven Fabrics 11 Mass per Unit Area (Weight) of Woven Fabrics 14 Width of Woven Fabrics 10 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 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 These test methods may be used for acceptance testing of commercial shipments; however, caution is advised because information about between interlaboratory precision is incomplete. Comparative tests as directed in 5.1.1 may be advisable. 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 statistical bias between them using competent statistical assistance. As a minimum, use test samples for such comparative tests that are as homogeneous as possible, drawn from the same lot of material as the samples that resulted in the disparate results during initial testing, and that are randomly assigned in equal numbers to each laboratory for testing. The test results from the laboratories should be compared using statistical test for unpaired data at a probability level chosen prior to the testing series. If a 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 These test methods are useful to evaluate quality and cost control during the manufacture of pile yarn floor covering. 5.3 The significance and uses of particular properties and test methods are discussed in the appropriate sections of the specified test methods.
