1.1 本试验方法包括测定拟用于面板和筛网系统的织物的尺寸稳定性，以循环改变湿度和温度。 1.1.1 面板和屏风系统包括隔音板、独立式屏风、办公室隔墙和家具系统。 1.2 以国际单位制表示的数值应视为标准值。国际单位制后括号中给出的值仅供参考，不被视为标准值。 1.3 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。 1.4 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 测量的织物尺寸稳定性决定了织物是否有可能保持其原始形状并保持稳定，表明其在基材上应用时不会随时间起泡或下垂，以及其是否适合指定用途。 5.2 建议将此测试方法用于商业装运的验收测试，但是，由于实验室间精度的信息不完整，因此建议谨慎使用。按照中的指示进行比较测试 5.2.1 是可取的。 5.2.1 如果两个实验室（或更多实验室）的报告测试结果之间存在实际意义上的差异，则应进行比较测试，以确定它们之间是否存在统计偏差，并使用主管的统计协助。至少，使用尽可能均匀的样品进行比较试验，从与初始试验期间产生不同结果的样品相同批次的材料中提取，并随机等份分配给每个实验室。 应使用未配对数据的统计测试对相关实验室的测试结果进行比较，这是在测试系列之前选择的概率水平。如果发现偏差，必须找到并纠正其原因，或者考虑到已知偏差，必须调整该材料的未来测试结果。 5.3 该测试方法在工业中用于确定织物在特定的湿度和温度条件下是否生长、生长然后收缩、收缩然后生长，或保持不变。

1.1 This test method covers the determination of the dimensional stability of fabrics that are intended for use on panel and screen systems to cycled changes in humidity and temperature. 1.1.1 Panel and screen systems include acoustic panels, free standing screens, office partitions, and furniture systems. 1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units 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 The measured dimensional stability of a fabric determines whether a fabric has the potential to retain its original shape and remain stable, indicating it will not bubble or sag over time, when applied over a substrate, and its suitability for a specified use. 5.2 This test method is recommended for acceptance testing of commercial shipments however, caution is advised since information about between laboratory precision is incomplete. Comparative tests as directed in 5.2.1 are advisable. 5.2.1 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. 5.3 This test method is used in industry to determine if a fabric grows, grows and then shrinks, shrinks and then grows, or remains the same when subjected to a specified range of humidity and temperature conditions.
