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. These include polymer potting compounds, foams, elastomers, films, tapes, insulations, shrink tubing, adhesives, coatings, fabrics, tie cords, and lubricants.

A test procedure for collecting data and a test method for processing and presenting the collected data are included. The quartz crystal microbalances used in this test method provide a sensitive technique for measuring very small quantities of deposited mass. The test apparatus shall consists of four main subsystems: The values given in parentheses are for information only.

Deposition rates are measured during material outgassing tests.

This asym 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. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This test method covers a technique for r1559 data to characterize the kinetics of e155 release of outgassing products from spacecraft materials. Historical Version s – view previous versions of standard. Test Method B allows the flexibility of user-specified specimen and collector temperatures, material and test geometry, and user-specified QCMs. Test Method A uses standardized specimen and collector temperatures.

Pressures external to the sample effusion cell are less than 7 X 10 -3 Pa 5 X 10 -5 torr. There are two test methods in this standard:
