Minor

1. Corner gap exceeds tolerances.

2. Skin to rail gap exceeds tolerance.

3. Adhesive flash not cleaned off.

4. Rivet too close to edge of skin.

5. Cocked rivet.

6. Weight exceeds maximum.

4.4.2.6. Rejection and retest. When a specified sample (see 4.4.2.2) from a lot fails to meet the

specification, acceptance of all pallets in the lot shall be withheld until the extent and cause of failure

have been determined. The contractor shall fully explain to the Government representative the cause of

failure and the action taken to preclude recurrence. After correction of the lot, all of the sampling tests

shall be repeated on one pallet from this lot.

4.4.2.6.1 Individual tests may continue. For production reasons, individual tests or other sampling

plans may be continued pending the investigation of a sampling test failure. However, final acceptance

of the entire lot shall not be made until it is determined that the lot meets all the requirements of the

specification.

4.4.2.6.2 Defects in pallets already accepted. The investigation of a test failure could indicate that

defects may exist in pallets already accepted. If so, the contractor shall fully advise the procuring

activity of all the defects likely to be found and the method of correcting them.

4.4.3 Adhesive tests. For each 4 hours run of pallets cured, 1 test specimen shall be fabricated for

production rates of 1 to 20 pallets per day; 2 test specimens shall be fabricated for production rates of

21 to 40 pallets per day; for production rates of 41 pallets or more per day three 3 test specimens shall

be fabricated. The specimens shall be 4 x 9 x 2.250 inches thick (tolerances on width and length,

+0.500 -0.062 inch; thickness, +0.125 -0.031 inch). All test specimens shall be fabricated from the

same materials as the pallets, processed and bonded in the same manner as the pallets they represent.

Specimens shall be tested as specified (see 4.5.10).

4.4.3.1 Tensile shear tests. Tensile shear tests shall be performed in accordance with MMM-A-132,

test number 1. These tests shall be performed as specified (see 3.2.3) for quality control of adhesives

and processing solutions.
