1.1本试验方法描述了根据粘合剂是否导致应力样品开裂来确定粘合剂与塑料兼容性的程序。 1.2给出了试样配置和测试夹具设计。 1.3本试验方法适用于片状或条状产品。它也可用于注塑拉伸试样或弯曲钢筋。 1.4以国际单位制表示的数值应视为标准。括号中的英寸-磅单位仅供参考。 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和健康实践，并确定监管限制的适用性。 ====意义和用途====== 本试验方法旨在获得塑料和粘合剂兼容性的定性估计。由于与塑料零件制造相关的过程变量很多，因此不可能使用此测试替代实际零件上的兼容性测试。 裂纹或银纹的检测可在有或无光学辅助的情况下确定。仅在采用等效灵敏度裂纹检测方法的试验之间进行比较。

1.1 This test method describes a procedure for determining the compatibility of adhesives with plastics based on whether the adhesive causes cracking of stressed samples. 1.2 Specimen configurations and test fixture designs are given. 1.3 This test method is suitable for products in the form of sheet or strip. It can also be used on injection molded tensile specimens or flexural bars. 1.4 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only. 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 and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== This test method is designed for obtaining a qualitative estimate of the compatibility of plastics and adhesives. Due to the many process variables associated with the fabrication of plastic parts, it is not possible to use this test as a substitute for compatibility tests on actual parts. The detection of cracks or crazes may be determined with or without optical aid. Make comparisons only among tests employing crack detection methods of equivalent sensitivity.
