ASTM E1559 – 09(2016)

Pressures external to the sample effusion cell are less than 7 X 10 -3 Pa 5 X 10 -5 torr. Deposition rates are measured during material outgassing tests. The values given in parentheses are for information only. Test Method A uses standardized specimen and collector temperatures. Deposition rates are measured during material outgassing tests. Test Method A uses standardized specimen and collector temperatures.

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. Test Method B allows the flexibility of user-specified specimen and collector temperatures, material and test geometry, and user-specified QCMs.

It is informational only and w1559 an official part of the standard; the full text of the standard itself must be referred to for its use and application.

The test apparatus shall consists of four main subsystems: Historical Version s – view previous versions of standard. The quartz crystal microbalances used in this test method provide a sensitive technique for measuring very small quantities of deposited mass.

Test Method B allows the flexibility of user-specified specimen and collector temperatures, material and test geometry, and user-specified QCMs.
