1.1 本试验方法确定了毛圈布快速吸收和保留来自人体皮肤、餐具和家具等表面的液态水的能力。 1.2 本试验方法不适用于非毛圈织物，如哈克毛巾、华夫格织毛巾、防撞毛巾、面粉袋毛巾和无纺布湿巾。仪器上试样的陡角可能导致大量水从这些非起毛织物中流出，或者这些织物的轻质/开放结构可能允许大量水完全通过试样；因此，测试结果可能不是非- 毛圈布的吸水能力。 1.3 本试验方法不适用于不用于吸收表面水分的装饰性毛圈布。 1.4 本测试方法采用国际单位制。提供的英寸-磅单位不一定完全等同于国际单位制。本试验方法中可以使用任何一种单元系统。在裁判决定的情况下，以国际单位制为准。 1.5 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。 1.6 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 本试验方法可用于测试毛巾、浴巾、手巾、厨房毛巾、抹布、毛巾、海滩装、浴衣等的毛圈织物的表面吸水性。由于应用不同，每种织物可能需要不同的规格。 5. 5.2 众所周知，表面吸水性只是最终消费者在确定哪种毛圈布是可接受的时可能使用的特征之一。参考规范 D5433 适用于毛圈布的其他特性。 5.3 本试验方法推荐用于制造商、零售商和用户在制造和产品比较不同毛圈布期间对毛圈布进行质量控制试验。 5.4 本试验方法可用于商业运输毛圈布的验收试验，但由于实验室间精度较差，建议谨慎。 按照中的指示进行比较测试 5.4.1 可能是可取的。 5.4.1 如果使用本测试方法进行商业装运验收测试时，由于报告测试结果的差异而产生争议，买方和供应商应进行比较测试，以确定其实验室之间是否存在统计偏差。建议为调查偏差提供称职的统计协助。作为最低要求，双方应采取一组实验室取样装置（如毛巾），这些取样装置应尽可能均匀，并且来自大量相关类型的材料。 然后，应将实验室采样单元以相等数量随机分配给每个实验室进行测试。应使用对未配对数据的适当统计分析和双方在测试开始前选择的可接受概率水平，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。

1.1 This test method determines the ability of a terry fabric to rapidly absorb and retain liquid water from surfaces such as human skin, dishes, and furniture. 1.2 This test method is not applicable to non-terry fabrics such as huck towels, waffle-weave towels, crash towels, flour-sack towels, and nonwoven wipes. The steep angle of the specimen on the apparatus may cause a large amount of water to runoff these non-pile fabrics, or the lightweight/open structure of these fabrics may allow a large amount of water to completely pass through the specimen; thus the test result may not be a valid measure of a non-terry fabric's ability to absorb water. 1.3 This test method is not applicable to decorative terry fabrics that will not be used to absorb water from surfaces. 1.4 This test method is written in SI units. The inch-pound units that are provided are not necessarily exact equivalents of the SI units. Either system of units may be used in this test method. In case of referee decisions the SI units will prevail. 1.5 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. 1.6 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 may be used to test the surface water absorption of terry fabrics for bath towels, bath sheets, hand towels, kitchen towels, dishcloths, washcloths, beachwear, bathrobes, and the like. Different specifications may be needed for each of these fabrics because of different applications. 5 5.2 It is recognized that surface water absorption is only one of the characteristics that the ultimate consumer may use in determining which terry fabric is acceptable. Consult Specification D5433 for other characteristics that may be applicable to terry fabrics. 5.3 This test method is recommended for quality control testing of terry fabrics during manufacturing and product comparisons of different terry fabrics by manufacturers, retailers, and users. 5.4 This test method may be used for the acceptance testing of commercial shipments of terry fabrics, but caution is advised since interlaboratory precision is known to be poor. Comparative tests as directed in 5.4.1 may be advisable. 5.4.1 In case of a dispute arising from differences in reported test results when using this test method for acceptance testing of commercial shipments, the purchaser and the supplier should conduct comparative tests to determine if there is a 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 laboratory sampling units (such as towels) that are as homogeneous as possible and that are from a lot of material of the type in question. The laboratory sampling units should then be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using appropriate statistical analysis for unpaired data and an acceptable 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 supplier must agree to interpret future test results with consideration of the known bias.
