1.1 本试验方法涵盖使用简单且经济的应用静态重量加载技术测量任何类型高放样非织造布的抗压性和恢复性能。 1.2 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。 1.3 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。 1.4 本试验方法提供了两种测量抗压性和恢复性能的方法。选项1包含更少的步骤，因此更简单。选项2进行了更多测量，并提供了有关这些测试条件下织物行为的更多细节。 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 highloft非织造布抵抗压缩和恢复的能力以及压缩后的弹性损失是两个基本物理特性，测量这些特性可以为某些最终应用设定规格。该测试方法为highloft生产商、其供应商和客户提供了一种廉价的替代方法，以确定抗压性和恢复性能，从而更好地预测其在成品中的性能。 5.2 highloft非织造布的抗压性和恢复性能要求将根据终端而变化- 使用应用程序。家具、床上用品和工业应用不需要相同的房地产价值来满足其个人消费者的需求。它们需要抗压性和一定程度的恢复能力。 5.3 该测试方法的选项1用于商业装运的验收测试。选项2的压缩恢复图有助于比较不同高放样非织造布的性能。 5.3.1 如果因使用本试验方法时报告的试验结果的差异而产生争议，买方和供应商应进行比较试验，以确定其实验室之间是否存在重大统计偏差。 建议为调查偏差提供称职的统计协助。作为最低要求，双方应尽可能均匀地从大量相关材料中提取一组试样。应将测试样品以相同数量随机分配给每个实验室进行测试。应使用适当的未配对样本统计测试和双方在测试开始前选择的接受概率水平来比较两个实验室的平均结果。如果发现偏差，必须找到并纠正其原因，或者买方和供应商必须同意在考虑已知偏差的情况下解释未来的测试结果。 注1: 买方和供应商之间的适当规范或协议要求考虑转鼓之间和转鼓内的可变性，以提供有意义的生产者风险、消费者风险、验收质量水平和限制质量水平。

1.1 This test method covers the measurement of compression resistance and recovery properties of any type of highloft nonwoven fabric using a simplistic and economical applied static weight loading technique. 1.2 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. 1.3 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. 1.4 This test method offers two options for the measurement of compression resistance and recovery properties. Option 1 contains fewer steps and is, therefore, simpler. Option 2 makes more measurements and provides more details about the behavior of a fabric under these test conditions. 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 ability of a highloft nonwoven fabric to resist compression and recovery and elastic loss after compression are two basic physical properties that are measured to set specifications for certain end-use applications. This test method provides an inexpensive alternative for highloft producers, their suppliers and customers to determine compression resistance, and recovery properties thus better predicting their performance in the finished product. 5.2 Compression resistance and recovery performance requirements of highloft nonwovens will vary according to the end-use application. Furniture, bedding apparel, and industrial applications do not require the same property values to satisfy their individual consumers. They will require resistance to compression and the ability to recover to some degree. 5.3 Option 1 of this test method is used in the trade for the acceptance testing of commercial shipments. Compression recovery graphs from Option 2 can be helpful in comparing performance of different highloft nonwoven fabrics. 5.3.1 In case of a dispute arising from differences in reported test results when using this test method, the purchaser and the supplier should conduct comparative tests to determine if there is a significant statistical bias between their laboratories. Competent statistical assistance is recommended for the investigation of bias. As a minimum, the two parties should take a group of test samples that are as homogeneous as possible and that are from a lot of material of the type in question. The test samples should be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using an appropriate statistical test for unpaired samples and an acceptance probability level chosen by the two parties before the testing is begun. If a bias is found, either its cause must be found and corrected or the purchaser and the supplier must agree to interpret future test results with consideration of the known bias. Note 1: An adequate specification or the agreement between the purchaser and the supplier requires taking into account the variability between rolls and within rolls to provide a meaningful producer’s risk, consumer’s risk, acceptance quality level, and limiting quality level.
