PART IB - PAINT MATERIAL REQUIREMENTS This part of the specification covers general requirements and methods of 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 OR
11、DERS 5 PACKING AND SHIPPING 6 5.0 CLASSIFICATION OF PAINTS Paints are classified by use of designations for both appearance and grade, 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
12、 special requirements are specified in the grade designation. A typical paint identification number is shown by the following example: 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, iv
13、ory) 5 = Green 6 = Blue 7 = Violet (mauve) 8 = Gray 9 = White Shade of Basic Color Gloss 60 Industry Designation for NAVISTAR Color numbers NA Textured 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
14、, pink, etc.) on the basic color code chart are intermediate colors arbitrarily classified under the basic color to avoid confusion. A = 85 5 B = 75 5 C = 65 5 D = 55 5 E = 45 5 F = 35 5 G = 25 5 H = 15 5 J = 10 5 K = 15 - 20 L = 10 - 15 M = 5 - 10 N = 2 - 5 Note: when the first digit is zero and th
15、e second is a number other than zero, the second digit will designate the color family. Example: 0311 Orange.

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 involved except for Grades 17, 18,
17、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 paint, and the “T” a special
18、 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 Black 5.1.1 When referring o
19、nly 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 indicating the basic color a
20、nd 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 be used when full gloss is req
21、uired 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 QUALITY All paints furnished under this specification will be f
22、ormulated 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 materials are furnished in advance o
23、f 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 compatible with zinc coated steel.
24、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 samples received in small u
