1.1 这些试验方法涵盖了在以下工作荷载和条件下测量饰面地板性能的程序: 部分 负荷试验 集中装载 7. 小面积荷载引起的地板表面压痕 12 落球压痕 18 滚动载荷 23 机械试验 耐磨性 28 摩擦系数 33 水分测试 表面润湿 38 1.2 以英寸-磅单位表示的数值应视为标准值。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。 1.3 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前建立适当的安全、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====== 3.1 本文提出的试验方法旨在提供评估饰面地板适用性的事实和比较方法。开发的程序模拟了一些使用条件，这些条件可能需要进行超出正常范围的维护或更换地板表面材料。 3.2 对于某些评估而言，重要的是要复制饰面地板下方使用的基材，因为支撑的类型和程度将直接影响从测试中获得的值。 例如，在一些现代建筑中，低密度材料用于紧靠饰面地板下方的隔音。该基材分布载荷和吸收能量的方式将对诸如滚动和集中载荷的评估产生影响。 3.3 本文提出的试验方法可用于比较不同饰面地板对严重和普通工作荷载的耐受性，也可作为设定规范限值的手段。除了刚度、强度、硬度和尺寸稳定性等基本材料性能外，还需要通过这些试验方法获得的性能。 3.4 任何特定调查可能不需要进行所有测试。两个测试之间可能存在相互关系，当证明了相互关系时，只需要在研究的最后阶段进行完整的评估。 因此，在每种情况下，有必要确定应进行哪些评估以实现目标。

1.1 These test methods cover procedures for measuring the performance of finish flooring under the following service loadings and conditions: Section Loading Tests Concentrated Loading 7 Floor Surface Indentation from Small Area Loads 12 Falling-Ball Indentation 18 Rolling Load 23 Mechanical Tests Abrasion Resistance 28 Coefficient of Friction 33 Moisture Tests Surface Wetting 38 1.2 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. 1.3 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 ====== 3.1 The test methods presented herein are intended to provide both a factual and comparative means of appraising the suitability of finish flooring. The procedures developed simulate some conditions of use that may require either maintenance beyond that considered normal or replacement of the floor surface material. 3.2 It is important for some of the evaluations that the substrate to be used beneath the finish flooring be duplicated because the type and degree of support will have a direct influence on the value obtained from test. For example, in some present-day construction, low-density materials are used for sound-deadening immediately below the finish flooring. The way this substrate distributes loading and absorbs energy will have an influence on evaluations such as those in rolling and concentrated loads. 3.3 The test methods presented herein may be used to compare different finish floorings as to their resistance to severe and ordinary service loads and also may serve as the means to set specification limits. The properties obtained by these test methods are needed in addition to such basic material properties as stiffness, strength, hardness, and dimensional stability. 3.4 All tests may not be required for any specific investigation. There may be an interrelation between two tests, and when it has been demonstrated what the interrelation is, a complete evaluation is only required as a final stage of a study. In each instance, therefore, it is necessary to determine which evaluations shall be made to fulfill the objectives.
