1.1本规程描述了在粘接试样之前使用的塑料粘附物的表面处理。然而，应注意，本规程仅规定了塑料的预处理条件，不包括试样制备、测试条件或测试评估。具体材料的各种ASTM测试方法或规范中涵盖了这些内容。 1.2 物理治疗 （例如，砂光和溶剂擦拭）用于去除粘合表面的光泽和所有污垢、油脂、脱模或其他污染物的痕迹。 1.3 化学处理 （例如，硫酸重铬酸盐溶液和萘钠络合物）在某些情况下用于化学改变聚合物本身的表层，以改善其粘附特性。 1.4以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 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。 6.1中给出了具体的预防说明。

1.1 This practice describes surface preparations for plastic adherends, to be used prior to adhesive bonding of test specimens. It should be noted, however, that this practice specifies only the pretreating conditions of the plastic and does not cover the preparation of test specimens, testing conditions, or evaluation of tests. These are covered in the various ASTM test methods or specifications for specific materials. 1.2 Physical Treatments (for example, sanding and solvent wiping) are used in order to remove the glossy finish and all traces of dirt, grease, mold release, or other contaminants from the bonding surfaces. 1.3 Chemical Treatments (for example, sulfuric aciddichromate solution and sodium naphthalene complex) are used in some cases to alter chemically the surface layers of the polymer itself to improve its adhesion characteristics. 1.4 The values stated in SI units are to be regarded as the standard. The values 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. Specific precautionary statements are given in 6.1.
