The baffle material covered by this specification is intended for use in aircraft fuel tanks using gasoline or kerosene type fuels at temperatures from −48.3° to +71.1°C (−55° to +160°F) for explosion and fire suppression. Types IV and V baffle material may be used in dry bay areas (cavities) up to 71.1°C (160°F) (vapor). Temperatures greater than 71.1°C (160°F) and high humidity conditions will shorten the service life. Use of types I, II, and III baffle material in dry bay areas is not recommended.

The storage life of the baffle material covered by this specification is not limited, provided it is maintained in the original sealed polyethylene bag plus opaque overwrap at temperatures below 32.2°C (90°F). Storage should be in an area cut of direct sunlight and outside weather, including high humidity and temperature. The material should be inspected for evidence of discoloration or surface deterioration (loss in tensile properties) prior to use.
