汽车聚酰胺(PA)塑料分类系统

[中文适用范围]： 本 SAE 推荐做法为汽车行业中使用的有限数量的聚酰胺（尼龙）提供了分类和规范系统。基于 ASTM D 4066@ 尼龙注射和挤出材料 (PA)@ 分类系统@，它需要汽车行业常用的附加描述性特征和属性。本文件仅适用于天然和非颜色匹配的黑色@热稳定聚酰胺化合物。颜色匹配的化合物应由专有的 OEM 标准定义。本文件允许使用回收@重组@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@并且材料应被标识像这样。目的 - 本文档的目的是：标准化用于汽车工业的未增强和增强聚酰胺（尼龙）66@ 6@ 和 66/6 的等级 b．标准化用于表征这些材料特性的测试方法 c．提供一种通过使用简单的线条标注指定来指定这些材料的方法 [外文原描述]： This SAE Recommended Practice provides a system for classification and specification for limited number of polyamides (nylons) used in the Automotive Industry. Based upon ASTM D 4066, Classification System for Nylon Injection and Extrusion Materials (PA), it calls for additional descriptive characteristics and properties commonly used in the Automotive Industry.This document applies to natural and non-color matched black, heat-stabilized polyamide compounds only. Color matched compounds shall be defined by the proprietary OEM StandardDetails.This document 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.Cross Reference: ASTMD3763,ASTMD4066,ASTMD5279,ASTMD789,ASTME831,FMVSS302,ISO/DIS294-1,ISO/DIS294-3,ISO/DIS294-4,ISO105/A02,ISO1183,ISO178,ISO180,ISO1874,ISO188,ISO295,ISO3146,ISO3167,ISO3451/4,ISO3795,ISO527,ISO62,ISO75,ISO960,J1344_201703,J1756,J1885,J1960,J1976_201204,J1976_202205,J369_201306,J369_201908
