The test sstm shall consists of four main subsystems: 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.

Test Method A uses standardized specimen and collector temperatures.

ASTM E1559 – 09(2016)

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

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. Historical Version s – view previous versions of standard. A test procedure for collecting data and a test method for processing and presenting the collected data are included.

There are two test methods in this standard: Deposition rates are measured during material outgassing tests. Deposition rates are measured during material outgassing tests.

These include polymer potting compounds, foams, elastomers, films, tapes, insulations, shrink tubing, adhesives, coatings, fabrics, tie cords, and lubricants. Test Method B allows the flexibility of user-specified specimen and collector temperatures, material and test geometry, and user-specified QCMs. The values given in parentheses are for information only. A test procedure for collecting data and a test method for processing and presenting the collected data are included.
