1.1 本试验方法包括在规定的制备和试验条件下试验时，测定一个刚性被粘物和一个柔性被粘物之间的粘合剂粘合的相对抗剥离性。 1.2 被粘物厚度的变化通常会影响测试值。因此，用于制作试样的板材的厚度应在材料规范中规定。当未指定厚度时，柔性被粘物应为0.63 mm（0.025 in.）厚，刚性被粘物应为1.63 mm（0.064 in.）厚。 1.3 以SI单位表示的值应被视为标准。括号中给出的值仅供参考。 1.4 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。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法规限制的适用性。 1.5 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》中确立的国际公认的标准化原则制定的。 ======意义和用途====== 5.1 使用本试验方法进行验收和过程控制试验。该测试方法可用作测试方法的替代方法 D1781 当该设施不可用时。由于剥离角度较大，因此认为该试验方法更严格。

1.1 This test method covers the determination of the relative peel resistance of adhesive bonds between one rigid adherend and one flexible adherend when tested under specified conditions of preparation and testing. 1.2 A variation in thickness of the adherends will generally influence the test values. For this reason, the thickness of the sheets used to make the test specimens shall be specified in the material specification. When no thickness is specified, the flexible adherend shall be 0.63 mm (0.025 in.) thick and the rigid adherend shall be 1.63 mm (0.064 in.) thick. 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.4 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. 1.5 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 Use this test method for acceptance and process control testing. This test method may be used as an alternative to Test Method D1781 when that facility is not available. This test method is considered more severe since the angle of peel is greater.
