This is only applicable to material received in this state by a using Navistar facility. 4.5 Processing Finished painted production parts shall be produced by the same metho
21、ds used on the qualification samples. Changes in processing must be approved by Materials Engineering. 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 shall be free from objection
22、able 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 Materials Engineering for approval 5.1 Porosity In instances where porosity is not detec
23、table 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 of the supplier to correct this co
24、ndition. 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. 5.2 Appearance Requirements Specific appearance
