1.1 本试验方法涵盖了测定应用于平面刚性表面（如金属板）的涂层上的有机涂层对泰伯研磨机产生的磨损的耐受性。 1.2 在确定涂层厚度时，以国际单位制表示的数值应视为标准值，但密耳除外。 1.3 本标准在内容上与ISO 7784–2相似（但在技术上不等同）。 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。 1.5 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 基材上的涂层在其使用寿命内可能因磨损而损坏。该试验方法有助于评估涂层的耐磨性。该试验方法产生的额定值与试验方法中下降磨料值产生的额定值密切相关 D968 . 5.2 对于某些材料，由于试验过程中车轮磨损特性的变化，使用泰伯研磨机的磨损试验可能会发生变化。根据磨料类型和试样，由于试验过程中产生的碎屑粘附，车轮表面可能会发生变化（即堵塞），并且必须按照相关方约定的更频繁的间隔重新表面。为了确定是否需要更频繁地重新铺筑表面，绘制每50个循环的总重量损失。如果在500个循环之前观察到坡度显著负变化，则坡度变化的点决定了重铺频率。 5.3 在评估两个或多个涂层的耐磨性时，可能需要考虑其他因素以进行准确比较。包括夹带气泡的柔性涂层可能会在比较试验期间改变质量损失。包含致密填料的涂层可能会导致更大的质量损失，但涂层厚度变化较小。包括二氧化硅、金属氧化物或其他密度极高的颗粒的涂层可能会磨损砂轮。包含极致密颗粒的磨损碎屑可能会导致三体磨损，从而导致断裂- 如果未通过真空抽吸系统去除，则涂层会向下移动。硬度值或摩擦系数大于砂轮的涂层可能会导致砂轮更快分解。在比较试验期间，必须考虑具有不同摩擦系数额定值的涂层。可能受到影响的涂层示例包括但不限于:；环氧树脂、聚甲基丙烯酸甲酯（PMMA）、聚氨酯甲基丙烯酸酯（PUMA）、甲基丙烯酸甲酯（MMA）和碳树脂。 注1: 实例 -20密耳厚的聚氨酯涂层嵌入1.2µm钛颗粒，导致涂层厚度损失2.1密耳，质量损失110 mg。没有钛颗粒的类似氨基甲酸乙酯涂层，导致2.9密耳至3.1密耳 mil涂层厚度损失和44 mg质量损失。

1.1 This test method covers the determination of the resistance of organic coatings to abrasion produced by the Taber Abraser on coatings applied to a plane, rigid surface, such as a metal panel. 1.2 The values stated in SI units are to be regarded as the standard, with the exception of mils when determining coating thickness. 1.3 This standard is similar in content (but not technically equivalent) to ISO 7784–2. 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 Coating on substrates can be damaged by abrasion during its service life. This test method has been useful in evaluating the abrasion resistance of coatings. Ratings produced by this test method have correlated well with ratings produced by the falling abrasive values in Test Method D968 . 5.2 For some materials, abrasion tests utilizing the Taber Abraser may be subject to variation due to changes in the abrasive characteristics of the wheel during testing. Depending on abradant type and test specimen, the wheel surface may change (that is, become clogged) due to the adhesion of debris generated during the test and must be resurfaced at more frequent intervals as agreed upon by the interested parties. To determine if more frequent resurfacing is required, plot the total weight loss every 50 cycles. If a significant negative change in slope is observed prior to 500 cycles, the point at which the slope changes determines the resurfacing frequency. 5.3 When evaluating resistance to abrasion of two or more coatings, other factors may need to be considered for an accurate comparison. Flexible coatings that include air entrainment bubbles could alter the mass loss during comparison tests. Coatings that include dense fillers may result in greater mass loss but have less change in coating thickness. Coatings that include silica, metal oxides or other extremely dense particulates, may wear the abrasive wheel. Wear debris that includes extremely dense particulates may cause three-body abrasion that contributes to the break-down of the coating if not removed by the vacuum suction system. Coatings that have a hardness value or coefficient of friction greater than the abrasive wheel may cause the abrasive wheel to break down faster. Coatings that have different coefficient of friction ratings, must be taken into consideration during comparison tests. Examples of coatings that may be impacted include, but are not limited to; epoxies, polymethyl-methacrylate (PMMA), polyurethane-methacrylate (PUMA), methyl-methacrylate (MMA), and carbon resin. Note 1: Example —A urethane coating of 20 mil thickness, embedded with 1.2 µm titanium particles resulted in a 2.1 mil loss in coating thickness and 110 mg mass loss. A similar urethane coating without titanium particles, resulted in a 2.9 mil to 3.1 mil loss in coating thickness and 44 mg mass loss.
