inspection system or quality program. The absence of any inspection requirements in the specification shall not relieve the contractor of the responsibility of ensuring that all products or supplies submitted to the Government for acceptance comply with all requirements of the contract. Sampling inspection, as part of manufacturing operations, is an acceptable practice to ascertain conformance to requirements, however, this does not authorize submission of known defective material, either indicated or actual, nor does it commit the Government to accept defective material.
4.2 Classification of inspection. The inspection requirements specified herein are classified as follows:
a. Conformance inspection (see 4.3)
4.3 Conformance inspection. The conformance inspection shall consist of all the examinations and tests specified in table I. In the event that a test sample fails to meet any requirement of this specification, the lot (see 4.3.1) represented by the sample shall be rejected. At the option of the procuring activity, reduced testing may be permitted (see 6.2 and 6.2.1). Certification of conformance to the storage stability requirement (see 3.8) is permitted.
4.3.1 Lot formation. A lot shall consist of all the primer coating, of the same type, class, and color, manufactured at one time, forming part of one contract or order, and submitted for acceptance to the procuring activity.
4.4 Sampling.
4.4.1 Sampling for tests. Conformance inspection samples shall be selected in accordance with FED-STD-141, method 1022.
4.4.2 Sampling of filled containers. A random sample of filled containers shall be selected in accordance with ASQC-Z1.4 (see 6.4).
4.5. Test panels. When test panels are required for testing, they shall be prepared under laboratory conditions (see 4.6). With the exception of surface appearance (4.6.3) and flexibility (4.6.6), all tests panels shall be aluminum alloy 2024,conforming to QQ-A-250/4 (T3 temper), with approximate dimensions of 0.020 by 3.0 by 6.0 in. (0.5 by 76.2 by 152.4 millimeters (mm)), and treated with chemical conversion materials conforming to MIL-C-81706, class 1A.
4.5.1 Primer coating application. Primer coating shall be applied to test panels (see 4.5) to a dry film thickness of 0.6 to 0.9 mils (15 to 23 microns ( m)). When required for spray
application, the viscosity of the packaged primer coating may be reduced with thinner conforming
MIL-T-81772, type III. Do not add thinner to the type II primer coating if the addition of the primer will increase the VOC above 340 g/l (2.8 lb./gal). Unless otherwise stated in the test
