1.1 该测试方法基于现有测试方法 D3359 ，经过修改，使其适用于柔性基板、印刷电子设备和薄膜开关。 1.2 尽管在塑料基材上进行胶带测试存在一些问题，但我们相信这仍然是测试薄膜开关或印刷电子设备应用中油墨和涂层附着力的最佳方法之一。在编写本测试方法时，我们正在解决对测试方法的几个异议，这些异议可能会影响其在塑料基材上的精度和重复性。 1.3 这些测试方法涵盖涂层或油墨对基材的附着力是否在可接受水平。它们不区分更高的附着力水平，因此可能需要更复杂的测量方法。 注1: 应当认识到，油墨或涂层表面粘附性的差异可能会影响使用具有相同固有粘附力的油墨或涂层获得的结果。 1.4 在多涂层系统中，涂层之间可能发生粘附失效，因此无法确定涂层系统与基材的粘附力。 1.5 本试验方法专门用于测量厚度小于等于5密耳（125微米）的油墨和涂层（薄膜）在聚酯和聚碳酸酯等塑料上的附着力。 1.6 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和健康实践，并确定监管限制的适用性。 ====意义和用途====== 5.1 如果油墨或涂层要实现其功能，就必须粘附在基材上。基材及其表面处理对油墨或涂层的附着力有显著影响。因此，一种评估油墨或涂料对不同基材或表面处理的附着力，或不同油墨或涂料对同一基材和表面处理的附着力的方法对该行业非常有用。 5.2 在使用之前，应认识到所有粘附方法的局限性以及本试验方法对较低粘附水平的具体局限性。该测试方法的实验室内和实验室间精度正在评估中。 5.3 待测试的打印区域应为足够大的实心区域，以包括整个交叉填充图案。

1.1 This test method is based on existing Test Method D3359 , with modifications to make it suitable for flexible substrates, printed electronic devices and membrane switches. 1.2 Despite the problems associated with a tape test on plastic substrates, it is our belief that this is still one of the best ways to test ink and coating for adhesion for membrane switch or printed electronic device applications. In writing this test method we are addressing several of the objections to the test method that could affect its precision and repeatability on plastic substrates. 1.3 These test methods cover whether the adhesion of coating or ink to a substrate is at an acceptable level. They do not distinguish between higher levels of adhesion, for which more sophisticated methods of measurement may be required. Note 1: It should be recognized that differences in adherability of the ink or coating surface can affect the results obtained with inks or coatings having the same inherent adhesion. 1.4 In multi–coat systems adhesion failure may occur between coats, so that the adhesion of the coating system to the substrate is not determined. 1.5 This test method is specifically designed for measuring adhesion of inks and coatings (films) that have a thickness of 5 mil (125 microns) or less, on plastics such as polyester and polycarbonate. 1.6 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 and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== 5.1 If the ink or coating is to fulfill its function, it must adhere to the substrate. Substrates and their surface preparation have a significant effect on the adhesion of inks or coatings. Therefore, a method of evaluating adhesion of inks or coatings to different substrates or surface treatments, or of different inks or coatings to the same substrate and surface treatment, is useful to the industry. 5.2 The limitations of all adhesion methods and the specific limitation of this test method to lower levels of adhesion should be recognized before using it. The intra– and inter–laboratory precision of this test method is under evaluation. 5.3 Printing area to be tested should be a solid area large enough to include the entire cross hatch pattern.
