13、TAR CEMS GT-23 SSPC-VIS-2 NAVISTAR CEMS GT-4D NAVISTAR CEMS GT-29 NAVISTAR CEMS GT-5A ASTM D 1186 5.0 CLASSIFICATION Paint grades are classified by chemical composition, durability and application. 5.1 Class of FinishThe Class of finish for specific products will be established by appropriate design
14、 engineering personnel in conjunction with the Industrial Design and Materials Engineering Groups. This specification will form the basis for uniform inspection standards for both manufactured and purchased parts. All materials utilized must conform to the requirements for the appropriate Class and
15、Grade for the finish specified. All deviations from this specification must be approved by the appropriate Materials Engineering Department. 6.0 GENERAL REQUIREMENTSThis specification is not intended to limit or specify the metal pretreatment or painting process but note that iron phosphate is not r
16、ecommended for zinc or aluminum coated substrates. When a chemical surface pretreatment is required, any process such as zinc or iron phosphate, acid wash prime or conversion coating applied by spray, immersion, or steam cleaning which results in finished parts meeting the requirements of this speci
17、fication will be approved. However, all systems from new vendors or deviations to this specification or changes in currently approved systems must be approved by Materials Engineering. 6.1 Finish RequirementsAll parts, whether painted by Navistar or purchased, will be finished with paints which meet
18、 all dry film requirements of the CEMS G-5 grade specified unless otherwise designated on the part drawing or purchase order. The resultant coating must match the appropriate Navistar color standard as well as meet ll of the requirements for the appropriate finish classification as shown in Table I.
