本文件总结了评估基材上涂层附着力的常用方法，基材可以是下面的另一层涂层，也可以是基材本身。试验方法和评估方法见第4、5和6条。对于标准化试验方法，在程序和评估方面参考相应的标准。附录A比较了天气表A.1、A.2和A.3中的方法。 通常，单一方法无法充分评估粘合强度。 测量粘合强度的纯物理方法是直接测量机械量（如力或扭矩）的方法。 所有其他方法都基于根据实际情况评估机械应力下的行为。对于这些方法，粘弹性特性对粘合强度的评估有广泛的影响，因此只能在一种方法中进行比较测试。 每种方法都有其特定的应用。不合适的方法可能会导致错误信息。所有用于评估粘合强度的测试方法都需要测试人员的特定常规，尤其是在识别分离线方面。对于大多数测试方法，测试结果取决于待测试涂层的膜厚度。此外，对于几种方法，由于基板的粗糙度不同，在测试板上进行的测试与实际测试之间可能会出现差异。 由风化或腐蚀影响引起的分层影响不在本文件范围内。 如果粘结强度试验期间主要发生粘结失效，则这不是粘结强度的衡量标准。但是，可以提供有关涂层防腐效果的信息。

This document summarises the common methods for evaluating the adhesive strength of coatings on a substrate, which can be another coating beneath or the substrate itself. The test methods and evaluation methods are described in Clauses 4, 5, and 6. In the case of standardized test methods the respective standard is referenced in regard to procedure and evaluation. Annex A compares the methods in the synoptic Tables A.1, A.2, and A.3. Often the adhesive strength cannot be sufficiently evaluated by means of a single method. The purely physical methods for measuring the adhesive strength are such in which mechanical quantities (e.g. force or torsion moment) are measured directly. All other methods are based on the evaluation of behaviour under mechanic stress according to practical conditions. For these methods the viscoelastic properties have a wide influence on the evaluation of the adhesive strength, so that it can only be tested comparatively within one method. Each method has its specific application. An unsuitable method can lead to false information. All of the test methods for the evaluation of the adhesive strength require a certain routine of the test person, especially in regard to identifying the separation line. For most of the test methods the test results, among other things, depend on the film thickness of the coating to be tested. In addition, for several methods differences between tests on a test sheet and in practice can occur, due to different roughness of the substrate. Effects of delamination caused by weathering or corrosion influences are not subject of this document. In case cohesion failures predominantly occur during an adhesive strength test, this is no measure for the adhesive strength. However, information can be given on the protective effect of the coating against corrosion.
