5.2 Examination and Testing.
5.2.1 Suppliers are encouraged to use quality control (QC) techniques that exhibit control over their processes (e.g. (Statistical Process Control) SPC Techniques) as defined in American National Standards Institute (ANSI) Z1.1, Z1.2, and Z1.3 / American Society for Quality Control (ASQC) B.1, B.2 and B.3 that systematically reduce excess variations. If used, objective evidence shall be available that demonstrates overall measurement adequacy techniques and controls. These techniques shall ensure quality levels equal to, or greater than, those cited in applicable technical document or, herein.
5.2.2 End item inspection / testing may be used by offeror or the Government representative, as a means to determine the effectiveness of the inprocess quality controls. In process controls shall not be substituted for end item performance testing.
5.2.3 For those characteristics for which there are no such controls, or for end item performance test, lot by lot sampling for inspection / test shall be required. The sample unit shall be one marker. Sampling shall be in accordance with the American National Standards Institute (ANSI) / American Society for Quality Control (ASQC) Z1.4, Sampling Procedures and Tables for Inspection by Attributes.
5.2.4 An inspection lot shall consist of all like items submitted for inspection at one time. The inspection level for visual and dimensional testing shall be S-3 with an AQL of 4.0 percent defective. The inspection level for performance characteristics testing shall be S-1 with an AQL of 6.5 percent defective. The supplier must provide objective evidence (test and inspection records) that the presented material meets the requirements of the sampling plan as indicated above.
6. Performance Test: Unless otherwise specified, the test shall be conducted in an atmosphere of 210 ± 30C (64.50 – 75.20F) and a relative humidity of 50% ± 5%. Test paper shall be in accordance with A-A-2804A, type III white bond paper having a pH of 5.0 with a basis weight of 60 grams per square meter 7.6 kg (16 pound, 17 x 22 – 500). A tolerance of 5% is allowable. Paper for the Machine Writing Test shall have an additional requirement of 160-140 second 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.
6.1 Drying Time. Place a sheet of paper on a smooth, flat surface and partially cover with a second sheet of paper. Place a 115 gram weight 4.0 oz), approximately 31.75 mm (1.25 inches) in diameter, on top of the second sheet. Write a line on the exposed portion of the bottom sheet, allow to dry three seconds, and immediately draw the top sheet and the weight across the writing at a rate of approximately 101.6 mm (4.0 inches) per second. The writing shall not smear or smudge.
