Anotation

This test method covers a technique for generating data to characterize the kinetics of the release of outgassing products from spacecraft materials. This technique will determine both the total mass flux evolved by a material when exposed to a vacuum environment and the deposition of this flux on surfaces held at various specified temperatures. The quartz crystal microbalances used in this test method provide a sensitive technique for measuring very small quantities of deposited mass. There are two test methods in this standard: Test Method A and Test Method B. The test apparatus shall consists of four main subsystems: a vacuum chamber, a temperature control system, internal configuration, and a data acquisition system. A test procedure for collecting data and a test method for processing and presenting the collected data are included.
