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, Z1.3/ American Society for Quality Control (ASQC) B.1, B.2, and B.3 that systematically reduce excess variations. Objective evidence shall be available that demonstrates overall measurement adequacy techniques and controls. These techniques shall ensure quality levels to, or greater than, those cited in applicable technical document or, herein.
5.2.2 End item inspection/testing may be used by the offeror 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.
5.2.3 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 either one refill, pen or one pen set. 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 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.
5.3 Performance Testing: Testing should be performed on components whenever practical so long as recordkeeping renders traceability. Unless otherwise specified test shall be conducted in an atmosphere of ,twenty-one (21) degrees Centigrade ± five (5) degrees centigrade and 50 % ± 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 per the most current TAPPI T538 test method. Alternately, paper conforming to JCP-O-60 can be used as an alternate source.
