5.3.2 End item inspection/testing may be used by the offerror or the Government representative, as a means to determine the effectiveness of the in process quality controls. While in-process controls shall not be substituted for end item performance testing, they may be used when sampling for visual and dimensional conformance.
5.3.3 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. 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.
5.3.4 An inspection lot shall consist of all like items submitted for inspection at one time. The inspection level for visual and dimensional sampling shall be S-4 with an AQL of 2.5 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 (tests and inspection records) that the presented material meets the requirements of the sampling plan as indicated above.
5.4 Performance Characteristics Tests: Testing shall be performed on components whenever practical as long as recordkeeping renders traceability. Unless otherwise specified tests shall be conducted in atmosphere of twenty-one (21) degrees centigrade + five (5) degrees centigrade and 50% plus or minus 10% relative humidity. Test paper shall be in accordance with A-A-2804A, type III white bond paper having a pH value, average not less than 5.0 with a basis weight of 60 grams per square meter (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 seconds maximum smoothness on both sides using the Sheffield method for the most current TAPPI T538 test method. Alternately, paper conforming to JCP-O-60 can be used as an alternate source.
5.4.1 Drying Time. Place a sheet of paper on a smooth, flat surface and partially cover with a second sheet of paper. Place cylindrical weight, approximately 200 grams and about 25.4 mm (1 inch) on top of the second sheet of paper. Write a five letter word on the exposed portion of the bottom sheet, allow to dry 5 seconds. Immediately thereafter draw the top sheet and weight towards the top of the bottom sheet, across the written characters at a rate of approximately 10 cm per second. The writing should not smear when tested. Examine both sheets for compliance.
5.4.2 Machine Writing Test.
5.4.2.1 The machine test shall be conducted on a Anja model W-10A, Hartley model W10-F, Minitek writing test machines or equivalent capable of testing pens or refills, with the following parameters set:
