1.1 本试验方法 2. , 3. 以定性方式模拟金属粘合剂/底漆界面处粘合剂粘结接头上的力和影响。事实证明，它在确定和预测粘附体表面制剂的环境耐久性方面具有很高的可靠性。该方法已被证明与使用性能相关，其可靠性远高于传统的搭接剪切或剥离试验( 附注2 ). 注1: 虽然本试验方法适用于铝对铝的应用，但只要考虑到被粘物的厚度和刚度，它也可用于确定其他金属和塑料的表面耐久性。 注2: 该试验方法不是定量断裂强度试验方法。要测量断裂强度，请参见试验方法 D3433 . 1.2 以国际单位制表示的值应被视为标准。括号中给出的值仅供参考。 1.3 本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。本标准的使用者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 该测试主要是定性的，但在确定被粘物表面制备参数和粘合剂环境耐久性的变化方面非常有区别。该测试已在控制表面处理操作和筛选表面处理、底漆和粘合剂系统的耐久性方面得到应用。除了确定裂纹扩展速率并为其赋值外，还对粘合接头失效进行了评估和报告。例如，粘附失效；衔接失败；在测试期结束时打开试样后，注意到被粘物失效。

1.1 This test method 2 , 3 simulates in a qualitative manner the forces and effects on an adhesive bond joint at metal-adhesive/primer interface. It has proven to be highly reliable in determining and predicting the environmental durability of adherend surface preparations. The method has proven to be correlatable with service performance in a manner that is much more reliable than conventional lap shear or peel tests ( Note 2 ). Note 1: While this test method is intended for use in aluminum-to-aluminum applications it may be used for determining surface durability of other metals and plastics provided consideration is given to thickness and rigidity of the adherends. Note 2: This test method is not a quantitative fracture strength test method. To measure fracture strength see Test Method D3433 . 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 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 The test is primarily qualitative, but is very discriminating in determining variations in adherend surface preparation parameters and adhesive environmental durability. The test has found application in controlling surface preparation operations and in screening surface preparations, primer and adhesive systems for durability. In addition to determining crack growth rate and assigning a value to it, the adhesive–joint failure is evaluated and reported. For example, adhesion failure; cohesion failure; or adherend failure are noted after opening up the specimen at the conclusion of the test period.
