2、RMANCE, FUNCTIONAL EXTERIOR PARTS - MODERATE DUTY ESB-M2P29-A PAINT PERFORMANCE, FUNCTIONAL EXTERIOR PARTS - LIGHT DUTY ESB-M2P30-A NOT TO BE USED FOR NEW DESIGN 1. SCOPE: These specifications define the quality of a painted finish required for partially visible or non-visible exterior surfaces of a

3、utomotive parts. Two levels of quality are defined as follows: ESB-M2P29: For parts which are subject to less severe weathering, corrosion or functional requirements. ESB-M2P30: For parts which are primarily hidden but which require moderate weather corrosion resistance. 2. APPLICATION: This specifi

4、cation was released originally for a finish specified where adequate weather corrosion resistance is necessary. Two quality levels provide flexibility of application and are specified depending on use, position and exposure resistance required. 3. REQUIREMENTS: 3.1 SYSTEM COMPONENTS . Phosphate coat

5、 ESB-M3P1 or ESB-M3P2. . One coat baking enamel or primer system. Variation in durability is obtained by quality of the primer or enamel used and variation in film thickness. 3.2 FILM PROPERTIES 3.2.1 Initial Hardness Shall be sufficiently cured at time of packing to withstand normal handling and sh

7、.2.4 Film Thickness, min ESB-M2P29 . 0.0004 in (10 m). Primer or enamel may be applied by either spray, dip or flow coat methods. Minimum film thickness does not apply to areas less than 1/2 in (13 mm) from upper edges, holes, embossments, lap joints or seam extension, when parts are dipped or flow

8、coated. ESB-M2P30 . 0.0003 in (8 m), excluding areas within 1/2 in (13 mm) of upper edges, holes, embossments, lap joints or seam extensions. Primer or enamel is generally applied by dipping or flow coat, but may be electrostatic spray painted. 3.3 SALT SPRAY (FLTM BI 3-1) Finished parts or polished

9、 steel control panels shall withstand exposure to 5 % salt spray with no failure as follows: Polished Panels (Refer 3.3.2) Finished Parts (Refer 3.3.3) Hours Minimum Hours Minimum ESB-M2P29 120 48 ESB-M2P30 96 24 3.3.1 Failure is defined as (1) blistering in any area or (2) corrosion creepage or los

10、s of adhesion more than 1/8 in (3.2 mm) from scratches, scar marks, or sharp edges. Blistering, corrosion creepage or loss of adhesion in areas 1/4 in (6.2 mm) from upper edges, holes, embossments, lap joints or seam extensions of dipped or flow coated parts or panels shall not be considered failure

11、. 3.3.2 Production 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, polished steel panels of a

12、ny convenient size, scribed as specified in FLTM BI 3-1 before exposure. 3.3.3 Parts tested need not be scribed. They shall be representative of production and shall be exposed in a manner similar to panels. Because of variation in steel surface conditions which cannot be controlled in the cleaning

13、or painting process, minimum salt spray requirements for parts are lower than for control panels. 3.4 SUPPLIERS RESPONSIBILITY Material supplied to this specification must be equivalent to that originally approved. Changes in formulation or processing shall not be made without prior approval as desc
