1.1 这些测试方法涵盖了可以在四种常用应力模式下测试自粘物的程序，即:压剪、劈裂、爬升滚筒剥离和T形剥离，以及刚性到刚性、柔性到刚性和柔性到柔性粘附物的各种组合，包括木材、铝、钢板和塑料层压板。还提供了涉及冲击形成键的定量测试方法。提供三种压力模式:静态、滚动和冲击。由于有多种类型的接触粘合剂用于在不同的条件下粘接许多不同的材料，因此这些测试方法的设计允许用户选择测试模式、涂层厚度、温度和相对湿度条件、压力大小和模式、打开时间和粘接调节时间。 1.1.1 与autohesives一起使用的粘合剂形成过程不同于所有其他粘合剂，因此，测试autohesives需要的方法不同于其他ASTM标准提供的方法。 看见 附件A1 . 1.2 在每种测试模式下都可以选择粘附物。可以粘合在一起的粘附物的组合仅限于中所示的组合 附录X1 . 1.3 在每种测试模式下都可以使用压力施加方法。对于基板的特定组合，可用于施加压力的方法仅限于中所示的方法 附录X2 . 1.4 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.5 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。 具体预防说明见 7.5 . 1.6 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 这些试验方法中的应用程序产生的薄膜不存在刷洗、喷涂或抹平过程中固有的不规则、伪影和变化。因此，这些测试方法测量两个自粘性膜之间的自粘性结合强度，其形貌是自粘性本身的特征，而不是应用程序的伪影。建议在推断这些试验方法的结果时考虑这些信息。 5.2 测得的粘结强度的大小还取决于其他因素，如薄膜厚度、施加压力的方式、施加压力的大小和持续时间，以及测试各个阶段的温度和湿度。因此，这些参数的选择应与自动感觉的最终用途一致。 5.3 如果在使用这些测试方法进行商业装运验收测试时，由于报告结果的差异而产生争议，买方和供应商应进行比较测试，以诊断其实验室之间缺乏可重复性的原因。建议为精度调查提供称职的统计协助。作为最低要求，双方应选择一组试样，并目视检查其失效模式。然后，应使用学生的数据比较两个实验室的平均结果 t -在开始测试之前，双方应选择未配对数据的测试和可接受的概率水平。 图1 一种刀治疗器

1.1 These test methods cover procedures by which autohesives can be tested in four commonly practiced stressing modes, namely: compression shear, cleavage, climbing drum peel, and T-peel, and in various combinations of rigid-to-rigid, flexible-to-rigid, and flexible-to-flexible adherends that include wood, aluminum, steel flakeboard, and plastic laminates. Quantitative test methods that involve bond formation by impact are also provided. Three pressure modes are provided: static, roller, and impact. Because there are many types of contact adhesives being used to bond many different materials under widely differing conditions, these test methods are designed to allow the user to select the test mode, coating thickness, temperature and relative humidity conditions, pressure magnitude and mode, open time, and bond-conditioning time. 1.1.1 The bond-formation process used with autohesives is unlike that of all other adhesives and in consequence, testing of autohesives requires methods that are unlike those provided by other ASTM standards. See Annex A1 . 1.2 A choice of adherends is available in each test mode. The combination of adherends that can be bonded together is limited to those shown in Appendix X1 . 1.3 Methods for application of pressure are available in each test mode. For a particular combination of substrates, the means available for application of pressure are limited to those shown in Appendix X2 . 1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.5 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. Specific precautionary statements are given in 7.5 . 1.6 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 application procedures in these test methods yield films free of the irregularities, artifacts, and variations inherent in brushing, spraying, or trowelling. Accordingly, these test methods measure the strength of autohesive bonds between two autohesive films whose topography is characteristic of the autohesive itself rather than the artifacts of the application procedure. It is recommended that this information be considered in extrapolating results from these test methods. 5.2 The magnitude of the measured bond strengths also depends on other factors such as film thickness, the manner in which pressure is applied, the magnitude and duration of the application of pressure, and the temperature and humidity at various stages of the test. Accordingly, these parameters should be chosen in a manner consistent with the end use of the autohesive. 5.3 In case of a dispute arising from differences in reported results when using these test methods for acceptance testing of commercial shipments, the purchaser and the supplier should conduct comparative tests to diagnose the causes for lack of repeatability between their laboratories. Competent statistical assistance is recommended for the investigation of precision. As a minimum, the two parties should select a group of test specimens and visually examine their failure modes. The average results from the two laboratories should then be compared using Student’s t -test for unpaired data and an acceptable probability level should be chosen by the two parties before testing is begun.
