MFSC-SPEC-2223 (REV A), OUTGASSING TEST FOR MATERIALS ASSOCIATED WITH SENSITIVE SURFACES USED IN AN AMBIENT ENVIRONMENT (29 JUN 2007)., This specification covers the control of materials used in air volumes of controlled environments. These environments may be clean rooms, environmental chambers, or shipping containers. This document establishes requirements and defines test methods to evaluate these materials. This test method is primarily a material screening technique and is not necessarily valid for computing actual contamination on a system or component. The use of materials deemed acceptable in accordance with this test method does not ensure the system or component will remain uncontaminated. Contributing factors not addressed in this test which should be considered include quantity of material used, line-of-sight to sensitive surfaces, and hardware exposure environments, e.g. process cleanliness, ect. Therefore, subsequent functional, developmental, and qualification tests should be used as necessary to ensure material’s satisfactory performance. The purpose of this specification is to present the specification for materials that are used in ambient environment at temperatures of 40 degrees Celsius (C) or less and associated with contamination sensitive surfaces. These surfaces may include but are not limited to optics, windows, thermal “control” or “protective” surfaces.
