21、h no thin spots, runs, wrinkles, porosity, pits, blisters or nodules. Material supplied 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 evalua
22、tion should be submitted to Materials Engineering for approval 5.1 Porosity In instances 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 signif
23、icant 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 require close
