FEDERAL LAW
183.552 - Plastic encased fuel tanks:
Installation
(c) If the plastic is bonded to the surface
of a metallic fuel tank, the adhesive strength of the
metal to the plastic bond must exceed the cohesive strength
of the plastic.
|
Encasement of metallic (only non-ferrous tanks
are permitted) fuel tanks must be done carefully to avoid
accelerated corrosion. The adhesion of the encasement materials
to the surface of the fuel tank must prevent water from contacting
the fuel tank’s metallic material. This is the reason
for the requirement that the plastic’s cohesive strength
be less than the strength of the adhesive bond to the fuel
tank. If a failure of the encasement material is to occur,
it should fail within the encasement material rather than
pulling away from the surface of the fuel tank.
FIGURE
24 - Failure of Encasement Materials
TO COMPLY WITH THE LAW
- Should a failure occur to the encasement
material used with a metallic tank, the failure will
not occur at the joint to the surface of the fuel
tank.
