1.1 本试验方法涵盖亚麻纤维的仪器测色。 1.2 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值不一定是精确的等价物；因此，为确保符合本标准，每个系统应独立使用，且两个系统的值不得组合。 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 客观判断亚麻品质的标准不多。颜色是影响亚麻纤维质量的重要因素。原亚麻纤维的自然变化、各种加工步骤、纤维混合以及广泛的最终用途，都需要一种客观测量亚麻纤维颜色的标准方法。分光光度数据可以准确、精确地测定亚麻纤维的颜色。如实践中所述，通过将样本光谱数据与代表CIE标准观察者和CIE标准光源的数据相结合，通过样本测量获得色度数据 E308年 . 5.2 如果两个（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，则应使用主管统计协助进行比较测试，以确定它们之间是否存在统计偏差。 作为最低要求，使用尽可能同质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。相关实验室的结果应使用未配对数据的统计测试进行比较，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，必须调整该纤维样品类型的未来测试结果。

1.1 This test method covers the instrumental color measurement of flax fiber. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 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 Few standards exist to objectively judge flax quality. Color is an important factor in the quality of flax fiber. Natural variations in raw flax fiber, various processing steps, fiber blending, and a wide range of end uses contribute to the need for a standard method of objectively measuring the color of flax fiber. Spectrophotometic data provide an accurate, precise determination of the color of flax fiber. Colorimetric data are obtained through specimen measurement by combining specimen spectral data with data representing a CIE standard observer and a CIE standard illuminant, as described in Practice E308 . 5.2 If there are differences of practical significance between reported test results for two (or more) laboratories, comparative tests should be performed to determine if there is a statistical bias between them, using competent statistical assistance. As 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 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 a bias is found, either its cause must be found and corrected, or future test results for that fiber sample type must be adjusted in consideration of the known bias.
