24、Miami area, facing south at 5 deg from horizontal) In order to monitor interim durability, a panel shall be exposed for 12 months in Florida concurrently with the 18 month panel. Final approval shall be based on performance of the 18 month Florida exposure panel. Returned, completed Florida exposure
25、 panels shall be washed in their entirety with a soft foam pad using a 25 % Ford M-1034 soap solution. Next, the panels are rinsed with tap water, blown dry with clean compressed air, and then placed in a deionized water bath (temperature maintained at 32 +/- 1 C) for 16 h per FLTM BI 104-01. After
26、panels are removed from water bath and thoroughly blown dry, an “X“, to be located at the center of panel and 50 mm from the bottom, is scribed. This “X“ shall be 30 mm in height and 20 mm wide. The scribed “X“ is then tape-pulled with 3M brand 898-2 tape. There shall be no evidence of peeling or bl
27、istering. Note: If the completed Florida exposure panels require more thorough cleaning to facilitate proper evaluation, the lower 1/3 of the panels may be polished with Ford Custom Silicone Gloss cleaner, part number B7AZ-19530-AA, using a soft cloth. This procedure is performed only after the pane
28、ls have been previously washed and subjected to water immersion and the “X“ scribe tape pull. The panels shall show no more evidence of chalking, dulling, fading or other color change than the standard master sample on file in the Body Exterior Materials Engineering Section. Also, the panels shall b
29、e free from cracking and microchecking when examined with the aid of a light source such as a Berkey Colortran Multi-10Z Lamp, Model 100-301 using a Sylvania 120V FBY bulb. Any evidence of such cracking or microchecking is considered to be a failure. Note: The performance rating assigned to a comple
30、ted 18 months Florida exposure panel takes precedence over a panel of the same material exposed for 750 h per para 3.9.5.2. ENGINEERING MATERIAL SPECIFICATION WSB-M1J214-A1/A2 Page 7 of 7 Copyright 2003, Ford Global Technologies, Inc. 3.9.5.2 Accelerated Exposure 750 h (SAE J2020, Fluorescent UV and
31、 condensation apparatus cycle is 4 h condensing humidity at 50 C followed by 8 h fluorescent UV at 70 C) After panels are removed from apparatus and allowed to dry, an “X“, located at the center of panel and 50 mm from the bottom, is scribed. The “X“ shall be 30 mm in height and 20 mm wide. The scri
32、be is then tape-pulled with 3M 898-2 tape. There shall be no evidence of loss of adhesion, blistering or cracking. Dulling, chalking, or fading shall not exceed established limits. 3.9.6 Electrical Resistance The electrical resistivity of the paint must be such that it satisfied the requirements of the equipment in the plant using it.
