6.6 Material certification. Materials to be installed in submarines are to be controlled to prevent off-gassing
which contaminates the atmosphere and can result in health hazards to personnel or deleterious effects on
machinery. These controls are accomplished through the Submarine Material Control Program, which is described
in the Nuclear Powered Submarine Atmosphere Control Manual, S9510-AB-ATM-010 chapter titled "Material
Control Program". Under the Submarine Material Control Program, all materials considered for use on submarines
require certification and assignment of a usage category. Under the certification process, candidate materials are
selected by Navy activities or contractors, and a request for certification is submitted to the Naval Sea Systems
Command, ATTN: SEA 05S, 1333 Isaac Hull Avenue, SE, Stop 5160, Washington Navy Yard, DC 20376-5160 or
emailed to CommandStandards@navy.mil. The certification request is accompanied by detailed information,
including descriptions of the material, method of application, usage, and storage. A chemical analysis is conducted,
which is normally accomplished through off-gas testing. The off-gas test is required to be conducted in a
Government approved laboratory designated by the preparing activity. Information pertaining to this test
requirement may be obtained from the Naval Sea Systems Command, ATTN: SEA 05S, 1333 Isaac Hull Avenue,
SE, Stop 5160, Washington Navy Yard, DC 20376-5160 or emailed to CommandStandards@navy.mil. Based on
the chemical analysis results, a usage category is assigned to the material defining whether, and to what extent, the
material may be used on submarines.
