1. SCOPE:

1.1 Form: This specification covers a low-outgassing silicon (PVMQ) rubber compound in the form of molded rings.

1.2 Application: Primarily for us in interplanetary space and other hard vacuums from −75° to +150° C (−103° to + 302° F), with a minimum of condensable outgassing products. While within the earth's atmosphere, the silicone rubber compound is resistant to deterioration by ozone, smog, and weathering.

1.2.1 Seals conforming to this specification are intended for us in electrical connectors, components, assemblies, and vehicle segments on the external configuration of spacecraft, where no condensation can be tolerated on critical surfaces windows, optics, thermal control coatings, etc) when 0such critical surfaces may be as cold as 23° C (73° F) and the seal may be as hot as 150° C 302° F). Seals for man-inhabited areas of spacecraft may require additional testing and approval.

1.3 Safety - Hazardous Materials: While the materials, methods, applications, and processes described or referenced in this specification may involve the us of hazardous materials, this specification does not address the hazards which may be involved in such use. It is th sole responsibility of the user to ensur familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensur the health and safety of all personnel involved.
