JUNE 2009 Page 2 of 7 approval, no deviation in materials and/or manufacturing processes are permitted without approval by Materials Engineering. 4.2 Qualification Of Coatings 4.2.1 Material The initial qualification tests of paint shall be performed
12、on parts formed from the same material and by the same process in which the finished parts are specified. These panels shall be coated with the materials 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 coat
13、ings applied by the intended production process. These panels shall be submitted to Materials Engineering at TDTC 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 4.2.2.1 A minimum of two (2)
14、 parts shall be submitted for qualification for each test. 4.2.2.2 Prior to coating, the samples shall be cleaned with solvents or cleaners as necessary. This operation shall simulate production procedure. 4.2.2.3 The primer, if applicable, shall be applied to a minimum dry film thickness per the ma
15、nufacturers recommended process. 4.2.2.4 The coated samples shall be cured by means which simulate production procedures. 4.3 Testing Finish painted parts, primed or unprimed, when coated with approved materials will meet the applicable requirements listed in the Table 1. 4.4 Material Properties Tab
16、le 2 lists the required cured material properties. 4.5 Chemical Properties Table 3 lists the as-received chemical properties of the raw materials. This is only applicable to material received in this state by a using Navistar facility. 4.6 Processing Finished painted production parts shall be produc
17、ed by the same methods used on the qualification samples. Changes in processing must be approved by Materials Engineering at TDTC. 5.0 QUALITY Painted parts shall be adherent and uniform in color and texture, with no thin spots, runs, wrinkles, porosity, pits, blisters or nodules. Material supplied
18、shall be free from objectionable odor, be of uniform quality, and shall match performance properties of pre-production approved material. Pre-production samples of material sufficient for complete test and evaluation should be submitted to TDTC Materials Engineering for approval 5.1 Porosity In inst
19、ances where porosity is not detectable until after the primed substrate has been painted, isolated cases of porosity as defined in Table 4 shall not be cause for rejection. Porosity that is chronic and requires significant amounts of rework shall be cause for rejection and it is the responsibility o
20、f 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 require close cooperation with the paint facility and with Materials Engineering at TDTC. NUMBER:
