1.1 本试验方法描述了在干燥和潮湿条件下对人造纤维纱线耐磨性能的测量。 1.2 本试验方法适用于绳索和针织软管制造中使用的人造纱线。 1.3 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者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。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ===意义和用途====== 5.1 本试验方法旨在测试人造纤维纱线的干耐磨性和湿耐磨性。该试验方法适用于海洋环境中使用的绳索和各种应用的编织软管。该测试方法已用于线密度在65特至335特之间的纱线，但也可用于这些范围之外的纱线。 5.2 已知纱线与纱线之间的摩擦对耐磨性有显著影响。使用试验方法测定摩擦系数 D3412 。 5.3 迄今为止，已经进行了有限的实验室间相关性测试。已根据ASTM惯例进行了单实验室测试。应谨慎使用测试结果。 5.4 该测试方法旨在为特定应用提供额外数据，如 5.1 并且不用于质量控制或测试报告。 5.5 如果两个或多个实验室报告的测试结果之间存在实际意义上的差异，则应使用主管的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，所用的测试样本应尽可能均匀，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。具有既定测试值的其他材料也可用于此目的。两个或多个实验室的测试结果应使用未配对数据的统计测试进行比较，测试前应选择概率水平。如果发现偏差，必须找到并纠正其原因，或者必须根据已知偏差调整未来的测试结果。 5.6 该测试方法在一个或多个施加的张力下进行，该张力可能取决于纱线材料和尺寸。施加张力的数量和大小以及八个样本组的数量通常在材料规范或合同订单中达成一致。关于确定施加张力的适当数量和大小的指南，请参见 附件A2 。

1.1 This test method describes the measurement of abrasion resistance properties for manufactured fiber yarns in dry and wet conditions. 1.2 This test method applies to manufactured yarns used in rope and knitted hose making. 1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are provided for information only. 1.4 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. 1.5 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 This test method is intended for testing dry and wet abrasion resistance of manufactured fiber yarns. This test method is useful for ropes intended for use in the marine environment and for knitted hoses for various applications. The test method has been used with yarns having linear densities ranging from 65 tex to 335 tex, but may be used with yarns outside these ranges. 5.2 Yarn to yarn friction is known to have a significant influence on abrasion resistance. To determine the coefficient of friction, use Test Method D3412 . 5.3 Limited interlaboratory correlation testing has been conducted to date. Single-laboratory testing, in accordance with ASTM practices, has been conducted. Test results should be used with caution. 5.4 This test method is intended to provide additional data for specific applications such as mentioned in 5.1 and is not intended for quality control or test reports. 5.5 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 the test samples used should be as homogeneous as possible, be drawn from the material from which the disparate test results were obtained and be randomly assigned in equal numbers to each laboratory for testing. Other materials with established test values may be used for this purpose. The test results from the two or more laboratories should be compared using a statistical test for unpaired data, at a probability level chosen prior to testing. If a bias is found, either its cause must be found and corrected, or future test results must be adjusted in consideration of the known bias. 5.6 This test method is conducted at one or several applied tensions that may depend upon the yarn material and size. The number and magnitudes of applied tensions and the number of eight specimen sets generally are agreed upon in a material specification or contract order. Guidance on determining the appropriate number and magnitudes of applied tensions is given in Annex A2 .
