5.2.4 An inspection lot shall consist of all like items submitted for inspection at one time. The inspection level for end product examination (visual and dimensional) shall be S-4 with an AQL of 4.0 percent defective. The inspection level for performance testing shall be S-2 with an AQL of 4.0 percent defective. The supplier must provide objective evidence (tests and inspection records) that the presented material meets the requirements of the sampling plan as indicated above.

5.3 Performance Characteristics Tests: Testing shall be performed on components whenever practical so long as recordkeeping renders adequate traceability. Unless otherwise specified tests shall be conducted in an atmosphere of 295.15 degrees Kelvin + 2 degrees Kelvin temperature (22 degrees Centigrade + 2 degrees Centigrade) and 60% + 12% in relative humidity. Test paper shall be 25 percent white bond paper having a PH value, average not less than 5.0 with a basis weight of 75 grams per square meter (20 pounds, 17 x 22-500). A tolerance of + 5% is allowable. Paper for the Machine Writing Test shall have an additional requirement of 160-140 seconds maximum smoothness on both sides using the Sheffield method per the most current TAPPI T538 test method. Alternately, paper conforming to JCP-O-60 can be used as an alternate source.

5.3.1 Driving Time. Place a sheet of paper on a smooth, flat surface and partially cover with a second sheet of paper. Place a 200 gram weight on top of the second sheet of paper. Write a five letter word on the exposed portion of the bottom sheet, allow to dry (10 seconds, and immediately draw the top sheet and the weight across the writing at a rate of 10 cm per second. The writing shall not be smeared when tested. Examine both sheets for compliance.

5.3.2 Cap Off. With the cap removed, expose the rollerball writing instrument to the atmospheric conditions specified in the performance characteristics test for a period of 24 hours. Writeout requirements shall meet those specified in writing characteristics.
