PART IB - PAINT MATERIAL REQUIREMENTS This part of the specification covers general requirements and methods of
11、 test which apply to all paints. 3.0 CONTENTS PAGE CLASSIFICATION OF PAINTS 2 GENERAL REQUIREMENTS 3 QUALITY 3 METHODS OF TEST 5 DESIGNATION ON DRAWINGS AND PURCHASE ORDERS 5 PACKING AND SHIPPING 6 5.0 CLASSIFICATION OF PAINTSPaints are classified by use of designations for both appearance and grade
12、 separated by a dash. Color and gloss are specified in the appearance designation with gloss being 83 min unless otherwise indicated by a letter. Paint properties and special requirements are specified in the grade designation. A typical paint identification number is shown by the following example
13、 Appearance Designation Grade Designation 4 3 8 4 M T - Basic Color 0 = Black 1 = Brown (buff, tan, cream) 2 = Red (coral, pink) 3 = Orange 4 = Yellow (chartreuse, ivory) 5 = Green 6 = Blue 7 = Violet (mauve) 8 = Gray 9 = White Shade of Basic Color Gloss 60 Industry Designation for NAVISTAR Color n
14、umbers NATextured 2 9 T A - Hot Spray Applied T - Higher Baking Temperature W - Water Borne HS - High Solids Special Requirements The colors in parentheses (buff, tan, pink, etc.) on the basic color code chart are intermediate colors arbitrarily classified under the basic color to avoid confusion.

Suppliers are required to assume all patent liability. 2008 by Navistar, Inc. 5.1 Grade Designation The grade designation consists of two digits. The first indicates the Part of the specification involv
18、ed except for Grades 17, 18, and 19 which are covered in Part II, and the second refers to the requirements within the appropriate specification. A suffix is also occasionally used to indicate a special requirement. For example: “-29T.” The “2” represents Part II, the “9” quality requirements of the
19、 paint, and the “T” a special requirement (higher baking temperature). When referring to a specific paint, such as on a purchase order, the complete appearance and grade designation will be specified along with the color name. This will help avoid confusion. Examples: NAV 0483-18 Yellow NAV 0001L-29
20、 Black 5.1.1 When referring only to color, as in pamphlets or letters, appearance designation and color name will be specified. The grade designation is not necessary. Examples: NAV 4421 School Bus Yellow NAV 0311 Omaha Orange 6.0 GENERAL REQUIREMENTS 6.1 Color Requirement This consists of one digit
21、 indicating the basic color and either three digits or a letter and two digits indicating the serial number of the particular shade of the basic color. 6.2 Gloss Requirement Minimum gloss requirements are indicated by suffix letters to the color number in the appearance designation. No suffix will b
22、e used when full gloss is required or when specifying primers and casting sealers. 6.3 Texture Requirement When texturing is desired, the suffix “T” is added after the gloss indicator in the appearance designation. Texturing always requires a gloss designation. 7.0 QUALITYAll paints furnished under
23、this specification will be formulated and manufactured with good paint practice to comply with all applicable OSHA, FDA, and EPA regulations in addition to all details of the specification. They will be free from foreign matter and relatively toxic materials unless details of such hazardous material
24、s are furnished in advance of qualification. Primers will not contain chlorinated hydrocarbon solvents or possess an odor which is objectionable. Primers sprayed under normal conditions will atomize (break-up) properly and build without “orange peel.” Grades -54, -55, and -56 primers will be compati
25、ble with zinc coated steel. 7.1 Sampling Procedure To ensure correct results, tests for conformance to the requirements of this specification will be conducted on samples of the paint prepared according to the following procedure: 7.1.1 For initial qualification samples and representative production
26、 samples received in small unpressurized containers, stir the paint by hand with a spatula for one to two minutes. If the paint does not mix readily, do not proceed but contact the vendor. 7.1.2 Using mechanical shakers for small containers such as 3.8 liter (one gallon) cans and rolling machines fo
27、r large containers such as 208 liter (55 gallon) drums, thoroughly mix the paint in the as-received containers for at least 15 minutes. Do not mix water borne paints on shaker or excessive foam JUNE 2008 Page 3 of 6 Copyright Navistar International Corporation Provided by IHS under license with INTE

Mix pressurized containers for two to three minutes and immediately perform spray out tests. For a catalyzed system, mix the paint portion only. Do not mix the catalyst. 7.1
30、3 After mixing, allow sufficient time for bubbles of entrained air to dissipate. One to two minutes is generally sufficient. Puncture pressurized containers at highest point to allow propellant to escape slowly, then enlarge hole to permit removal of the paint. 7.1.4 With the paint at a temperature
31、 not less than 18C (65F), draw off into a clean, dry metal sample container enough paint to perform the tests required. With pressurized containers, transfer entire contents. Seal the sample container immediately. 7.1.5 Immediately before each test is started, stir the paint in the sample container
32、with a spatula to insure uniform sampling. 7.1.6 For one component system (standard type), draw off sufficient sample from the sample container for the particular test being conducted and immediately reseal the sample container. 7.1.7 For catalyzed systems, draw off a sufficient sample from the samp
33、le container and catalyst from the catalyst container keeping sample and catalyst in separate test containers. 7.1.8 For catalyzed systems, measure out the proper ratio of sample to catalyst from the test containers per manufacturers recommendations and mix them together thoroughly. 7.1.9 For single
34、 component systems, repeat (7.1.5) and (7.1.6) each time a sample is drawn from the sample container. 7.1.10 Repeat (7.1.2) each time a test requires the use of the pressurized container, except for CEMS GT-3F. 7.1.11 For two component systems, repeat (7.1.7) and (7.1.8) each time a sample and catal
35、yst are drawn from their respective containers for a catalyzed system. 7.1.12 For one component systems, all extra sample material may be saved for further use. For two component systems, discard all extra mixed sample material in a safe and proper way. 7.2 Engineering Qualification Production mater
36、ial can be furnished under this specification only after formal Engineering Qualification. The Purchasing department will request Materials Engineering at Truck Development and Technology Center to issue an Engineering Qualification to the supplier. Material submitted for qualification will be accom
37、panied by a sample part, detailed test information, and also certification that the material meets all requirements of this specification. 7.2.1 After the material has been tested by the approved facility, manufacturing plant trials will be conducted to assure that the proposed material is compatibl
38、e with production processes. On completion of these tests, all departments involved will be notified that the material has been either qualified or rejected. Prior to regular purchase, samples must be submitted for Manufacturing approval. 7.2.2 Material subsequently supplied to this specification wi
39、ll have the same formulation as the qualification samples. No change in composition or method of manufacture will be permitted without approval of Materials Engineering. Refer to the “Engineering Qualification” section in Volume 1 of the International Material Specifications Books for an outline of
40、how this procedure works. Note: Where there is no specific grade designation for a water borne, powder coat, or other non-classified paint, it may be qualified to the specification of the solvent system it replaces based on dry film properties.
