SCOPE These specifications def

3、ine the performance of a painted finish required for partially visible or non-visible exterior surfaces of automotive parts. Three levels of quality are defined as follows: ESB-M2P28: for parts which are primarily visible and are subject to severe weathering, corrosion or are required to be function

4、al over a long period of time. ESB-M2P29: for parts which are subject to less severe weathering, corrosion or functional requirements. ESB-M2P30: corrosion resistance. 2. APPLICATION These specifications were released originally for a finish specified where adequate weather corrosion resistance is n

5、ecessary. Three quality levels provide flexibility of application and are specified depending on use, position and exposure resistance required. 3. REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements

The specified minimum film thickness applies to all areas. . 0.0005 in (13 m) when parts zinc phosphate coated per ESB-M3P

9、1, are painted with electrocoat primer. . 0.0005 in (13 m) acceptable on dip or flow coat paint processes, provided the painted parts pass 96 h salt spray test without failure as defined in para 3.3.1. ESB-M2P29 . 0.0004 in (10 m). Primer or enamel may be applied by either spray, dip or flow coat me

ESB-M2P30 . 0.0003 in (8 m), excluding areas within 1/2 in (13 mm) of upper edges, holes, embossments, lap joints o

11、r seam extensions. Primer or enamel is generally applied by dipping or flow coat, but may be electrostatic spray painted. 3.3 SALT SPRAY RESISTANCE (FLTM BI 103-01) Finished parts and control panels shall withstand exposure to 5% salt spray with no failure as follows: Finished Parts (Refer 3.3.3) Co

15、oduction systems painting parts under this specification shall be tested periodically by running control panels through the complete system including metal cleaning and phosphate coat. Film thickness shall be representative of parts. Control panels shall be flat, 4 x 12 in (100 x 300 mm) approximate

16、ly 20 gauge unpolished, CRLC body steel identified as Paint Testing Quality (PTQ) steel by an embossed letter “F“ on the test side of the panel. Steel for these test panels is specified by Materials Engineering Department, BEPE and selected periodically from coil(s) representative of production stee

They shall be representative of production and shall be exposed in a manner similar to panels. Because of variation in steel surface conditions whi

18、ch cannot be controlled in the cleaning or painting process, minimum salt spray requirements for parts are lower than for control panels. 5.
