This will result in limited areas of lower single value strength. Such areas will not be allowed where they m
33、ay detract from the performance of the component. Therefore, the vendor will request and receive permission for such deviations from the Appropriate International engineering department prior to qualification of the molded part. Such request will detail the location(s), extent of orientation and min
34、imum strength value of all such deviations. * Type III and VI, C normally cannot be achieved by spray-up process. TABLE 3 SUFFIX REQUIREMENTS Property Suffix Requirements Surface Finish Quality A1 A1n Best surface on parts to be painted. Surface quality will be such that, after painting, the finish
35、is equivalent to that of painted sheet metal normal to the using International plant. There will be no visible fiber pattern, pinholing, cratering, waviness or other defects. Type II and Type IV will be made using “low-profile” resin systems. Type I and III will use gel coat and/or “low-profile” res
36、in systems. Achievement of the A1 surface finish requirement may necessitate the use of in-mold coatings. Where the use on in-mold coatings is required by Engineering it will be specified on the engineering drawing by means of a “Z” suffix requirement. Control of production parts will be accomplishe
37、d through comparison with master samples retained from the initial qualification of molded parts or by means of written acceptance standards for the individual part. When a second suffix numeral is shown, this designates a maximum surface finish of 100 times the second digit in microinches. A15 requ
38、ires a finish of 500 in (13m).

39、bility. 2014 by Navistar, Inc. February 2014 Page 5 of 12 TABLE 3 SUFFIX REQUIREMENTS (continued) Property Suffix Requirements Surface Finish Quality A2 Good surface on parts to be painted. After painting, surface will exhibit a finish approaching that of painted sheet metal. However, a very faint f
40、iber pattern will not be cause for rejection. A3 Minimum surface on parts to be painted. Surface preparation need only be sufficient to meet paint compatibility requirements. Fiber pattern and/or slight pinholing will not be cause for rejection. A4 A4n Best surface on parts not to be painted. Parts
41、will be free from fiber pattern (color or roughness), waviness or other defects when viewed with the unaided eye. Type I Prominent fiber pattern will be allowable. A9 Special finish; requirements will be stated on the part drawing. Surface Finish Compat- ibility B1n Parts will be compatible with pai
42、nt finishing operations employed by the using Navistar plant. Surface preparation will be sufficient to allow finishing paint top coat to meet dry film requirements, as well as the finish requirements of Suffix A. The suffix B1n indicates priming is not specifically required. However, priming is not
43、 precluded where necessary to meet the above requirements. After being subjected to standard NAVISTAR finishing operations wherein paint baking temperatures do not exceed the temperature designated by the second suffix numeral as shown below, parts will not delaminate, blister, shrink, warp or sag t
44、o the extent that function or appearance is impaired. The finish paint will not exhibit craters or pinholes. There will be no failure in adhesive bonded joints. The second suffix numerals indicate paint bake temperatures as follows: 0 as stated on drawing 5 - 310 F (154 C) 1 - 190 F (88 C) 6 - 340 F
45、 (171 C) 2 - 220 F (104 C) 7 - 370 F (188 C) 3 250 F (121 C) 8 - 400 F (204 C) 4 280 F (138 C) Example: B13 indicates a paint bake not exceeding 250 F (121 C). B2n Same as B1n except that priming is specifically required. Dry film properties will meet the requirements of CEMS G-5, Grade 52, or other
46、 stated requirements. B3n Same as B2n except that primed surface will be electrically conductive as necessary for electrostatic painting. B4n Same as B2n except that top coat of primer system will have a 60 gloss of 85 minimum for use as an inspection aid. B5n Same as B1n except that primed surface
47、will be electrically conductive as required for electrostatic painting. B8n Same as B1n except that surface preparation will be as specially detailed on the drawing or in referenced documents. B9n Parts will be finish painted by the vendor to match color or colors specified on the drawing. Dry film
48、properties will meet the requirements of the specified Grade per CEMS G-5 or other stated requirements.
