Metallic paints and plastics, key to the automotive industry, are characterized by luster and goniochromism, while the field’s terminology continues to evolve. ASTM has standardized methods for characterizing metallic surfaces, and modern portable multi‑angle instruments provide rapid, easy measurements under controlled viewing conditions. New instrumentation has been developed to deliver controlled viewing conditions for evaluating metallic materials. © 1996 John Wiley & Sons, Inc.
The use and characterization of metallic paints and plastics have been important, particularly in the automotive industry, throughout the last half of this century. The scientific concepts and terminology of this field are still evolving. The principal appearance characteristics of these materials, when viewed at a distance, are luster and goniochromism. Methods of characterizing and measuring metallic surfaces are being standardized by a committee of the American Society for Testing and Materials. New instrumentation has been developed to provide controlled viewing conditions for judging these materials. Modern portable multi-angle measuring instruments are easy to operate and take measurements very quickly. © 1996 John Wiley & Sons, Inc.
