13、rade 52HS as per CEMS G-5, Part V, prior to their first use in production. In addition, parts primed with the materials and applications processes/methods to be used by the supplier shall be approved by Materials Engineering and, after approval, no deviation in materials and/or manufacturing process
14、es are permitted without approval by Materials Engineering. 4.2 Qualification Of Paint 4.2.1 Material The initial qualification tests 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 co
15、ated with the paint to be tested using the procedure listed below. In cases where a primer is specified in addition to the topcoat, the panels shall contain both coatings applied by the intended production process. These panels shall be submitted to Materials Engineering at TDTC for approval with th
16、e vendors test results. Final qualification shall be performed on the finished part prior to production release. 4.2.2 Sample Preparation 4.2.2.1 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 clean
17、ers as necessary. This operation shall simulate production procedure. 4.2.2.3 The paint/primer shall be applied to a minimum dry film thickness 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 pr
18、oduction procedures. Baking cycles shall not be detrimental to the base plastic. 4.3 Testing Finish painted parts, primed or unprimed, when topcoated with approved materials will meet the applicable requirements listed in the Table below.
