2-5 Detailed Test Procedures.
a.
Water test after repair, After any major repair to an empty container, or when leaking is suspected, stream water
from a hose with an 0.5-inch nozzle at 15 psi against all repaired joints and seams for at least five seconds per
seam. Water entering the container indicates that the repair or gasket condition is unsatisfactory. Refer a badly
repaired container to direct support maintenance. If checking gasket condition, go on to repair procedures in
paragraph 2-7.
b. Light leak test.
(1)
Enter container and close doors completely.
(2)
Allow eyes to get used to the dark.
(3)
Turn on flashlight for orientation only. Do not shine flashlight beam on area you are inspecting.
(4)
Look for light from pin holes in container.
(5)
Mark pin hole locations with chalk for repair.
(6)
With flashlight on and aimed at inspection pointsclosely examine all welds, particularly where corrugations
and door posts join. Mark holes with chalk and refer to direct support for repair.
Section III. CARGO CONTAINER REPAIR
2-6. Container Body. Inspect corrugations for holes, tears, punctures and dents more than 1/4" deep. Damaged empty
containers and containers with holes larger than 144 square inches should be referred to the direct support level. Holes,
tears and punctures in the corrugations of a full container may be repaired by patching with fiberglass according to
paragraph 2-6.a.
Inspect the condition of the corner posts, corner fittings, and structural rail members. Containers showing damage to the
corner posts, side rails or corner fittings should be referred to direct support maintenance. Corner posts having a small
vertical dent which does not exceed 1/2 inch in depth and 12 inches in length do not require repair providing the corner
post/corner fitting joint is not affected.
