It is the responsibility of the user of this standard to sstm appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Deposition rates are measured during material outgassing tests. The test apparatus shall consists of four main subsystems: Test Method A uses standardized specimen and collector e1559.

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. Pressures external to the sample effusion cell are less than 7 X 10 -3 Pa 5 X 10 -5 torr. 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.

ASTM E1559 – 09(2016)

This abstract is a brief summary of the referenced standard. Deposition rates are measured during material outgassing tests. This test method covers a technique for generating data to characterize the kinetics of the release of outgassing products from spacecraft materials.
