1.1 本规程涵盖了在绒线地板覆盖物试样上旋转和移动的加重滚筒椅试验装置的操作程序。 1.2 本规程适用于测试所有类型的未使用绒线地板覆盖物。 1.3 以英寸磅为单位的数值应视为标准。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。 1.4 本标准并不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 本规程适用于测试所有类型的绒线地板覆盖物的耐久性。 5.2 该实践旨在模拟长时间内加重滚轮椅脚轮作用在绒线地板覆盖物上的应力。 5.3 样品在可能模拟实际地板安装的条件下进行测试。这可能包括绒线地板覆盖物加上指定的垫层。 5.4 本规程用于制备用于额外测试的试样，包括但不限于: 二次背衬分层的视觉评估，绒头表面的视觉评估、分层阻力测量、绒头粘合和绒头纱线散开。

1.1 This practice covers a procedure for the operation of a weighted roller chair testing device that rotates and moves across a test specimen of pile yarn floor coverings. 1.2 This practice is applicable for testing unused pile yarn floor covering of all types. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 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 practice is applicable for use in testing the durability of pile yarn floor covering of all types. 5.2 This practice is designed to simulate the stress on a pile yarn floor covering from the action of weighted roller chair castors over an extended period of time. 5.3 The specimen is tested under conditions that may simulate an actual flooring installation. This may include the pile yarn floor covering plus a specified underlayment cushion. 5.4 This practice is used to prepare specimens for additional testing, including but not limited to: visual assessment of delamination of the secondary backing, visual assessment of the pile surface, resistance to delamination measurement, tuft bind, and pile yarn raveling.
