MORE STRINGENT REQUIREMENT FOR OUTGASSING: The acceptance limits can be made more stringent if the materials concerned are used in critical areas.

The use of materials that are deemed acceptable according to the general requirement does not ensure that the spacecraft system or component remains uncontaminated. Outgassing data, derived from tests at K ( degree C) for 24 hours in vacuum as per ASTM Ehave been compiled for numerous materials for spacecraft use.

The data presented are the. The practice described here for the collection and compilation of vacuum outgassing data is used in conjunction with a number of other processes in the selection of materials. Vacuum outgassing tests are conducted on materials intended for space flight use, and a compilation of outgassing data, Reference 1, is maintained and constantly updated.
