1.1 这些试验方法描述了一种程序，用于通过目视检查建立织物分级的数字标志。 1.2 这些测试方法可用于交付和验收符合买方和供应商共同商定要求的织物。 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 试验方法 D5430 由于该方法已在贸易中广泛用于织物分级和织物验收测定，因此被认为适合于商业装运的验收测试。 5.2 当使用本文列出的三个选项中的每一个时，在对相同的卷轴或螺栓进行分级时获得的罚分可能会有很大的不同。因此，在因买方和供应商报告的值差异而产生分歧的情况下，应使用相同的点分配选项。 5.3 如果两个实验室（或更多实验室）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，以确定它们之间是否存在统计偏差，并使用适当的统计协助。 至少应确保使用的测试样品尽可能均匀，从获得不同测试结果的材料中提取，并以相同数量随机分配给每个实验室进行测试。应使用未配对数据的统计测试，在测试系列之前选择的概率水平上，比较两个实验室的测试结果。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。

1.1 These test methods describe a procedure to establish a numerical designation for grading of fabrics from a visual inspection. 1.2 These test methods may be used for the delivery and acceptance of fabrics with requirements mutually agreed upon by the purchaser and the supplier. 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 Test Method D5430 is considered satisfactory for acceptance testing a commercial shipments since the method has been used extensively in the trade for grading of fabric and fabric acceptance determination. 5.2 The penalty points obtained in grading the same rolls or bolts of fabric may vary considerably when using each of the three options listed herein. For this reason, the same point assignment option should be used in cases of disagreement arising from differences of values reported by the purchaser and the supplier. 5.3 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. As a minimum, ensure the test samples to be used are as homogeneous as possible, are drawn from the material from which the disparate test results ere obtained, and are randomly assigned in equal numbers to each laboratory for testing. The test results from the two laboratories should be compared using a 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.
