本SAE推荐规程为汽车行业中使用的有限数量的丙烯腈/丁二烯/苯乙烯（ABS）以及与聚碳酸酯（ABS+PC）塑料的混合物提供了分类和规范系统。基于ASTM D 4673（ABS）成型材料分类系统，它要求汽车行业常用的附加描述性特征和特性。本规程仅适用于天然、非配色的黑色和镀灰色化合物。颜色匹配化合物应由专有OEM标准定义。本规程允许使用回收、再造和再研磨材料，前提是满足本文件中规定的要求，材料未被改变或修改，以改变其安全加工和使用的适用性，并且材料应进行标识。

This SAE Recommended Practice provides a system for classification and specification for limited number of acrylonitrile/butadiene/styrene (ABS) and blends with polycarbonate (ABS+PC) plastics used in the automotive Industry. Based upon ASTM D 4673, Classification system for (ABS) Molding Materials, it calls for additional descriptive characteristics and properties commonly used in the Automotive industry.This practice applies to natural, non-color matched black, and plating gray compounds only. Color matched compounds shall be defined by the proprietary OEM standards.This practice allows for the use of recycled, reconstituted, and regrind materials provided that the requirements as stated in this document are met, the material has not been altered or modified to change its suitability for safe processing and use, and the material shall be identified as such.
