1.1 本试验方法包括使用称重触针测定柔性非导电薄膜和包装材料的耐磨性，该触针通过沿着线性路径来回振荡或往复运动，直到电路完成关闭试验，从而完全磨损薄膜。 1.2 单位- 以国际单位制或英寸磅单位表示的数值应单独视为标准。每个系统中规定的值可能不是完全相等的；因此，每个系统应独立使用。将两个系统的值合并可能导致不符合标准。 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。 1.4 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 诸如工程热塑性薄膜之类的材料通常用于柔性屏障包装。然而，处理和运输可能会导致包装薄膜磨损，并可能损害内容物的完整性（例如，医疗器械的无菌性）。 该测试方法提供了材料性能的比较排名，可作为相对最终使用性能的指示。 5.2 在实验室条件下，在试验机上测量材料表面的耐磨性，这只是在材料的实际使用中影响磨损性能或耐久性的几个因素之一。虽然耐磨性和耐久性经常相关，但这种关系随着不同的最终用途而变化，在根据特定磨损数据计算预测耐久性时，可能需要不同的因素。 5.3 材料表面的耐磨性可能受到以下因素的影响:温度和湿度的测试条件、磨料类型、试样和磨料之间的压力、试样的安装或张力，以及涂层或添加剂等饰面材料的类型、种类或数量。 变化的其他原因包括测试过程中的局部材料移动、材料方向对准、材料特性以及心轴和触针磨损。对于一致性，在特殊环境条件下评估的样品应在相同条件下进行处理。证明测试仪器在特殊环境条件下正常工作是很重要的。 5.4 此测试方法可能不适用于所有薄膜，包括以下情况: 5.4.1 在测试期间在磨损区域中拉伸并产生波纹的膜， 5.4.2 厚度大于0.25毫米（0.010英寸）的薄膜，或具有在心轴上形成会导致削弱薄膜的内应力的刚性的薄膜，以及 5.4.3 导电膜。

1.1 This test method covers the determination of the abrasion resistance of flexible non-conductive films and packaging materials using a weighted stylus that wears completely through a film by oscillating or reciprocating back and forth along a linear path until an electrical circuit is completed shutting down the test. 1.2 Units— The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the 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 ====== 5.1 Materials such as engineered thermoplastic films are often used for flexible barrier packaging. However, handling and transportation can cause abrasion to the packaging film and possibly compromise the integrity of the contents (for example, sterility of a medical device). This test method provides a comparative ranking of material performance that can be used as an indication of relative end-use performance. 5.2 The resistance of material surfaces to abrasion, as measured on a testing machine under laboratory conditions, is only one of several factors contributing to wear performance or durability as experienced in the actual use of the material. While abrasion resistance and durability are frequently related, the relationship varies with different end uses and different factors may be necessary in any calculation of predicted durability from specific abrasion data. 5.3 The resistance of material surfaces to abrasion may be affected by factors including test conditions of temperature and humidity, type of abradant, pressure between the specimen and abradant, mounting or tension of the specimen, and type, kind, or amount of finishing materials such as coatings or additives. Other causes of variation include local material movement during testing, material direction alignment, material characteristics, and mandrel and stylus wear. For consistency, samples to be evaluated under special environmental conditions shall be conditioned under those same conditions. It is important that the test instrument be shown to operate properly under special environmental conditions. 5.4 This test method may not be suitable for all films, including the following cases: 5.4.1 Films that stretch and generate a ripple in the abraded region during testing, 5.4.2 Films that have a thickness greater than 0.25 mm (0.010 in.), or are of such rigidity that forming over the mandrel would cause internal stresses that weaken the film, and 5.4.3 Conductive films.
