Outgassing of adhesives and coatings can cause problems in optics used in space applications. The actual test NASA runs on candidate materials is very expensive and time consuming. End users will typically test every batch of material they receive and reject any that do no pass the requirements. This paper discusses a test which acts as an indicator to measure the relative performance and determine if the manufactured material will pass the outgassing requirement without going through the actual ASTM test. This is not a substitute for the final test. Its purpose is for screening materials being used in manufacturing or research.
