SECTION II.

Maintenance Standards

5. Corner Casting (Fittings).

Replace the corner casting if cracked or broken. No repair is allowed no matter how small the crack. This

is critical for the safe handling of the container.

6. Corner Posts.

Replace corner post if torn, distorted or kinked. A small vertical or horizontal dent is acceptable if the

post/corner casting joint is not affected. Repair if not more than .75 inches (3/4 inch/19 mm) in depth, and

not more than 12 inches (.305 m) in length. If the dent exceeds these dimensions and the post/corner casting

joint is not affected, it must be straightened by heating or replacement. If the corner casting joint is

affected it must be repaired. After straightening, alignment of the comer casting must be within the

original design dimensions tolerance.

7. Side, Top and Bottom Rails.

a. If 10 feet or more (3.05 m) of the bottom rail is cut, torn, distorted or damaged by severe (stage IV)

corrosion, the entire length of the rail is to be replaced. If less than 10 feet (3.05 m), the damaged sec-

tion/area is to be removed and spliced with new material. No more than two splices per bottom rail is per-

mitted. The splice must extend for 12 inches (.305 m) minimum on each side of the damaged area. When the

damaged area is near the corner fitting so that the splice would end less than 12 inches (.305 m) from the

corner fitting, extend the splicing material and weld to the corner fitting. When the structural cross

members (SCM) fall in the area of the side rails that have been cut out, a 1.31 inch X 1.50 inch X .1345 inch

(.4 m X .458 m X .041 m) pad will be installed between the SCM and the splice plate (Drawing No.

13222E7283 applies).

b. If 10 feet (3.05 m) or more of the top rail is cut, torn, distorted or damaged by severe (stage IV) corro-

sion, the entire length of the rail is to be replaced. If less then 10 feet (3.05 m), the damaged section/area is

to be removed and spliced with new material. No more than two splices per top side rail is permitted. The

splice must extend 12 inches (.305 m) minimum on each side of the damaged area. When the damaged area

is near the corner fitting, so that the splice would end less than 12 inches (.305 m) from the corner fitting,

extend the splicing material and weld to the corner fitting. Drawing No. 13222E7283 applies.

8. Front and Rear, Top and Bottom Rail.

a. Front. If the top 4 feet (1.22 m) or more of the top or bottom rail is cut, torn, distorted or damaged by

severe stage IV corrosion, the entire length of the rail is to be replaced. If the damaged section is less than

4 feet (1.22 m), the damaged area is to be removed and spliced with new material. No more than one splice

per rail is permitted. The splice must extend for 12 inches (.305 m) minimum on each side of the damaged

area. When the damaged area is near a corner fitting, extend the splicing material and weld to corner fit-

ting. Drawing No. 13222E7283 applies.

b. Door Sill and Header. If the sill is cut, torn or distorted 4 feet (1.22 m) or more, the entire sill is to be

replaced; if less than 4 continuous feet (1.22 m), one splice is permitted. A splice must not interfere with

either the door seal or the operation of the locking mechanism. If the splice is within 12 inches (.305 m) of a

corner fitting, it is to be extended and welded to the corner fitting. If the sill is completely severed, it is to

be replaced. Drawing No. 13222E7283 applies.
