摘　　要：目的论述如何通过内、外饰零部件耐候性技术要求的控制,来满足整车在不同地区、不同气候的使用要求。方法通过分析户外自然老化结果的相关性,制定氙灯加速老化测试方法,并在此基础上制定相关要求。结果氙灯老化测试中辐照剂量的控制应以零部件进行分类,技术要求及外观评价应按材料种类进行分类,并分别制定限值要求。结论汽车内、外饰零部件耐候性质量的管控应从测试方法、技术要求、外观评价三方面加以严格控制。Objective To introduce a controlling method through the control of weathering technology requirements of inner/exterior parts, so as to meet the requirements of the vehicle in different regions and climate. Methods Through analysis the correlation of outdoor natural aging results, the test method of xenon lamp aging and relevant requirements was formulated. Results The irradiation dose test of xenon lamp aging should be classified base on the components and parts, the technical requirements and appearance evaluation should be classified according to the type of material, and then the limit requirements were respectively set out. Conclusion The quality control of interior / exterior parts of weathering test should be strengthened from the test methods, technical requirements, and the appearance evaluation.
