OCTOBER 2010 Page 2 of 6 4.0 GENERAL REQUIREMENTS 4.1 Finish Classification Class of finish of painted parts shall be specified on the Engineering drawing. Painted parts shall meet all requirements for the specified Type as described herein, includin
12、g both heat and corrosion requirements. 4.1.1 Type 1 For painted parts subjected to a maximum operating temperature of 1000 F (538C). Examples include select hanger brackets, exhaust castings, non-exhaust gas carrying stanchions, etc. These parts require good corrosion resistance combined with a hig
13、h level of heat resistance. 4.1.2 Type 2 For painted parts subjected to a maximum operating temperature of 1200F (650C). Examples include fabricated exhaust stanchion assemblies and other parts which carry hot exhaust gas directly through them. These parts require good corrosion resistance combined
14、with an exceptional level of heat resistance. 4.2 Pre-paint Preparation All surfaces to be painted, including weld metal and surrounding heat-affected zones (HAZ), shall be free of dirt, oil, grease, rust or other contaminants which may inhibit proper adherence of the high temperature paint. Wheneve
15、r possible, surfaces to be painted should exhibit “water-break free” characteristics, indicating a clean surface free of oil and other contaminates. An effective post-weld cleaning procedure is to be utilized and should include either an abrasive (e.g., bead blasting or needle descaler) or chemical
16、acid etch of the welded areas prior to painting. Additional care should be taken if the welded material is stainless steel to assure that any mechanical means of post-weld cleanup does not contaminate the weld and surrounding areas with iron or other elements which could negatively affect paint adhe
17、sion and/or underlying base metal corrosion resistance. The requirement for as-painted parts and assemblies, their weld metal and HAZ is a uniform, continuous paint film with no cracking, peeling, areas of major color change, or other major defects. 4.3 Paint Requirements 4.3.1 Dry Film Properties 4
18、.3.1.1 Thickness Painted parts and assemblies supplied to this specification must maintain a minimum dry film paint thickness per the paint manufacturers recommendation, unless otherwise noted and approved by NAVISTAR Materials Engineering. 4.3.1.2 Color Paint color will typically be black, unless o
19、therwise specified on the engineering drawing. 4.3.1.3 South Florida Exposure Paint must pass a 6-month South Florida Exposure test per the latest version of CEMS GT-7F. 4.3.1.4 Accelerated Weathering Accelerated weathering testing per the latest version of CEMS GT-31 (Method B) will be carried out
20、and color change evaluated. After testing, a E 1000 scfm) to promote rapid cooling. Components and assemblies must withstand eight cycles of this test with no significant change in paint appearance (e.g., fading or chalking), coating delamination, cracking, blistering, flaking, powdering, etc. NUMBE

22、TOBER 2010 Page 4 of 6 4.5 Post-Heat Corrosion Resistance 4.5.1 Type 1 After the heat cycling of section 4.4, Type 1 painted parts and assemblies will be subjected to 250 hours of neutral salt-fog exposure per ASTM B 117. At the conclusion of 250 hours, all major surfaces (excluding tube ends, inter
23、ior assembly surfaces, and sheared or cut edges) shall exhibit a Rust Grade 6 (S, G, and/or P types) or better per SSPC-VIS-2. 4.5.2 Type 2 After the heat cycling of section 4.4, Type 2 painted parts and assemblies will be subjected to 168 hours of neutral salt-fog exposure per ASTM B 117. At the co
24、nclusion of 168 hours, all major surfaces (excluding tube ends, interior assembly surfaces, and sheared or cut edges) shall exhibit a Rust Grade 6 (S, G, and/or P) or better per SSPC-VIS-2. For both Type 1 and Type 2 parts, care should be taken during evaluation to disregard rust bleed-down from bot
25、h edges and corrosion sites. Assessment should focus strictly on the size and density of actual corrosion sites. In addition to corrosion evaluation, there should be no evidence of paint delamination, film breakdown, blistering, porosity, or objectionable color change of the part in high heat exposu
26、re areas after salt-fog testing. 5.0 QUALITY 5.1 Qualification New suppliers shall submit a report certifying compliance to all requirements of this specification. No parts shall be shipped for production use prior to formal approval by TDTC Materials Engineering. 5.2 As-Received Appearance 5.2.1 As
27、-received painted parts and assemblies shall be free of uncoated areas (such as around welds, on edges, in bolt holes, and in crevices), excessive painted-over weld spatter, blisters, cracks and/or other paint-related defects. Painted surfaces shall be uniform in color and gloss and maintain a rough
28、ly flat or slightly glossy black (or other approved color) appearance. Visible surfaces will be free of gouges, scratches, indentations and/or other major surface defects which may negatively affect appearance or function. 5.2.2 Type 2 painted stanchion assemblies supplied to this specification shal
29、l be delivered in a clean and dry condition, without damage to the painted exterior surfaces and without uncoated areas. There should be no visible stencil markings on exterior visible surfaces. All inlet and outlet tubes shall be protected from damage during shipping and handling and will be adequa
30、tely sealed to protect against corrosion of the unpainted internal pipe surfaces. This should result in no significant corrosion scale being present on interior unpainted surfaces at the time of delivery. 5.3 Quality Control Plan A Quality Control Plan for this product will be established by mutual
31、agreement between NAVISTAR and the supplier. Unless specific exception is noted, the following characteristics, where applicable*, shall be included in the plan as features for management by statistical process control.* 1.
