本手册旨在介绍一种在真空环境中，通过光学表面、热控制表面或其他污染敏感表面的视线系统筛选非金属材料的方法。使用本文所述方法进行的排气测量将支持对材料表面分子污染物释放的构型分析，并有助于预测可冷凝材料在一个或多个相邻表面上的沉积。

The purpose of this handbook is to present a methodology for the systematic screening of nonmetallic materials with a line of sight to an optical surface, thermal control surface, or other contamination sensitive surfaces in a vacuum environment. The outgassing measurements made using the methods described here will support configurational analysis of the release of molecular contamination from the surface of a material and facilitate the prediction of the deposition of condensable materials on one or more adjacent surfaces.
