12、tions processes/methods to be used by the supplier shall be approved by Materials Engineering and, after approval, no deviation in materials and/or manufacturing processes are permitted without approval by Materials Engineering. 4.2 Qualification of Paint 4.2.1 Material The initial qualification tes
13、ts of paint shall be performed on parts molded from the same material and by the same molding process in which the finished parts are specified. These panels shall be coated with the paint to be tested using the procedure listed below. In cases where a primer is specified in addition to the topcoat,
14、 the panels shall contain both coatings applied by the intended production process. These panels shall be submitted to Materials Engineering for approval with the vendors test results. Final qualification shall be performed on the finished part prior to production release. 4.2.2 Sample Preparation 4
15、.2.2.1 A minimum two (2) parts shall be submitted for qualification for each test. 4.2.2.2 Prior to painting, the samples shall be cleaned with solvents or cleaners as necessary. This operation shall simulate production procedure. 4.2.2.3 The paint/primer shall be applied to a minimum dry film thick
16、ness to provide black/grey hiding (Morass chart) per the manufacturers recommended process. 4.2.2.4 The painted samples shall be cured by means which simulate production procedures. Baking cycles shall not be detrimental to the base plastic. 4.3 Testing Finish painted parts, primed or unprimed, when
17、 topcoated with approved materials will meet the applicable requirements listed in the Table below. Test Test Method Requirements Adhesion ASTM D3359, Method B 95% Min.

Porosity that is chronic and requir
25、es significant amounts of rework shall be cause for rejection and it is the responsibility of the supplier to correct this condition. The supplier has the responsibility to provide quality primed parts which will not cause delayed defects after finishing in the using plant. This condition will requi
26、re close cooperation with the paint facility and with Materials Engineering. 5.2 Appearance Requirements Specific appearance requirements are given in Table 1.
