1.1 本试验方法涵盖了羽毛成分的定量测定。本试验方法适用于散装或成品消费品中的羽毛。 1.2 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 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 本试验方法可用于散装羽毛商业装运的验收试验。散装羽毛的买方和卖方之间必须确定含量的验收公差，这也必须符合州和联邦机构的规定（视情况而定）。 5.1.1 如果因使用测试方法时报告的测试结果的差异而产生争议 D4524 对于商业装运的验收测试，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，双方应尽可能均匀地从大量相关类型的材料中选取一组试样。 然后，应将试样以相同数量随机分配给每个实验室进行测试。两个实验室的平均结果应使用学生的 t -测试未配对数据和双方在测试开始前选择的可接受概率水平。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根据已知偏差解释测试结果。 5.2 本试验方法也适用于将羽毛用作填充材料的消费品的验收。 这些消费品包括枕头、被子、睡袋、服装、家具和床垫。内容物的验收公差由分销商、进口商、州或联邦监管机构确定。看见 5.1.1 .

1.1 This test method covers the quantitative determination of the components found in plumage. The test method is applicable for plumage found in bulk form or in finished consumer products. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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 This test method may be used for acceptance testing of commercial shipments of bulk plumage. Acceptance tolerances of content must be established between the purchaser and seller of bulk shipments of plumage, which also must comply with state and federal agency regulations, as appropriate. 5.1.1 In case of a dispute arising from differences in reported test results when using Test Method D4524 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 test specimens that are as homogeneous as possible and that are from a lot of material of the type in question. The test specimens should then be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using Student's t -test 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 the supplier must agree to interpret test results in the light of the known bias. 5.2 This test method may also be applicable to the acceptance of consumer products that use plumage as a filling material. Such consumer products include pillows, comforters, sleeping bags, garments, furniture, and mattresses. Acceptance tolerances of content are established by distributors, importers, state or federal regulatory agencies. See 5.1.1 .
