A certificate of compliance shall be submitted and will be acceptable for the stated requirements.

Only the stain on the polyamide fibers of the color transfer cloth shall be evaluated.

A thickness gauge of the dead-weight type equipped with a dial graduated to read directly to

0.0001 inches shall be used. The presser foot shall be circul~, with a diameter of 0.375 ~

0.0001 inches and with the moving parts weighted to apply a total load of 3.4< 0.1 pounds per square inch to the specimen. The anvil shall be not less than 0.250 inches m diameter.

The presser foot and anvil surface shall be planed to within 0,0001 inches. The micrometer shall be capable of repeating its reading to 0.00005 inches af zero setting or on a steel gauge block.

The pretension load (pounds) shall b equivalent to 1 percent of the minimum rated specification breaking strength requirements.

The test specimens shall be exposed in the accelerated weathering unit as specified in method A.ATCC 111A Option 4. The unbacked specimen shall be placed in a stairdess steal holder or suspended from the rack. Corex D filters and sunshine carbons shall be used. The exposure time shall be 50 hours. The spray heads shall be shut off during the entire exposure period.

The relative humidity conditions shall be 55 ~ 5 percent throughout the test cycle. At the end of the exposure period, the specimens shall be brought to equilibrium under standard ccmd~tionsas defined in AATCC 111A,Option 4. The sp&imens shall then be tested for breaking strength as specified and the percent of breakhg strength (B. S.)loss shall be calculated as follows:

Ori~inal Average B.S. - Ave. B.S. after a~ing X 100=% B.S. loss Original Average B.S.

The test specimens shall be suspended in a circulation air oven a temperature of 1800 C ~ 3° C (3560 F ~ 5oF) for 1 hour. After removal from the oven, the specimen shall be brought to equilibrium under standard conditions (700 F ~ 20 and 65% RH ~ 2%). The specimens shali then be tested for breaking strength as specified in Table I and the percent of breaking strength 10SSshall be calculated as follows:

OriEinal Ave B.S. - Ave B.S. after aging X 1,00= % of B.S. loss Original AVE B.S.

5. PACKAGING

5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see 6.2). When actual packaging of materiel is to be performed by DoD personnel, these personnel need to contact the responsible packaging activity to ascertain requisite packaging requirements. Packaging requirements are maintained by the Inventory Control Point’s packaging activity within the Military Depamment or Defense Agency, or within the Military Department’s System Command. Packaging data retrieval is available from the managing Military Department’s or Defense Agency’s automated packaging files, CD-ROM products, or by contacting the responsible packaging activity.
