Standard Test Method for Resistance to Yarn Slippage at the Sewn Seam in Woven Upholstery Fabrics 机织装饰织物中缝纫接缝处纱线抗滑移性的标准试验方法
发布日期: 2019-11-01
1.1 本试验方法通过比较缝合和未缝合样品的试验曲线差异,使用特定的标准接缝组件测量机织室内装饰织物中经纱在填充纱上或在经纱上填充纱的抗滑移性。 注1: 本试验方法源自试验方法 D434页 ,对其进行了适当的更改,使该方法更适用于室内装饰织物。 注2: 本试验方法设计为织物试验,在技术上与试验方法不同 D1683 ,这被认为是纱线/接缝测试。 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 试验方法 D4034 对于织物纱线滑动阻力的测量,认为其符合机织室内装饰织物的验收测试要求。 5.1.1 如果在使用本测试方法进行验收测试时,由于买方和供应商报告的数值差异而产生分歧,统计偏差(如有),供应商的实验室和买方的实验室之间的比较应基于对从被评估为尽可能同质的大量材料中提取的样本的测试来确定,然后以相等数量随机分配给每个实验室。 5.2 本试验方法旨在在受控条件下测量装饰织物缝合缝处的织物纱线滑移。该测试方法可能无法指示实际的现场性能。 5.3 不符合买方和供应商之间约定要求的织物应归类为“精细纱线抗滑移”,并通知买方和家具制造商。
1.1 This test method measures the resistance to slippage of warp yarns over filling yarns, or filling yarns over warp yarns, in woven upholstery fabrics, using a specific standard seam assembly by comparing the differences in test curves from a sewn and unsewn sample. Note 1: This test method is derived from Test Method D434 , from which appropriate changes have been made to make the method more applicable for upholstery fabrics. Note 2: This test method is designed to be a fabric test and is considered to be technically different than Test Method D1683 , which is considered to be a yarn / seam test. 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 Test Method D4034 for measuring the resistance to fabric yarn slippage is considered satisfactory for acceptance testing of woven upholstery fabrics. 5.1.1 In case of disagreement arising from differences in values reported by the purchaser and the supplier when using this test method for acceptance testing, the statistical bias, if any, between the laboratory of the supplier and the laboratory of the purchaser should be determined with comparisons being based on the testing of specimens taken from a lot of material of the type evaluated to be as nearly homogeneous as possible and then randomly assigned in equal numbers to each of the laboratories. 5.2 This test method is intended to measure fabric yarn slippage at the sewn seam in upholstery fabrics under controlled conditions. This test method may not indicate actual field performance. 5.3 Fabrics that do not meet the requirements agreed upon between the purchaser and supplier should be classified as “delicate yarn slippage resistance” and the purchaser and furniture manufacturer so notified.
