It involves exposing steel panels which have been coated with the rust preventative o

3、r draw compound in question to a condensing water vapor atmosphere. The panels are then evaluated, cleaned and phosphated and subsequently reevaluated.

Conditioning and Test Conditions All test values indicated herein are based on material conditioned in a controlled atmosphere of 23 +/- 2 C and 50 +/- 5 % relative humidity for not less th

8、an 24 h prior to testing and tested under the same conditions unless otherwise specified. Procedure Procedure “A“ - Drawing Oils and Compounds 1. Lay steel panels horizontally on a flat surface over paper toweling. Wipe polished surface clean with isopropanol. Air dry thoroughly. 2. Mix compounds as

9、 specified by plant use, Manufacturing Standard or supplier recommendations. 3. Apply oil or mixed compound to upper quarter of panel face, drawing down with applicator (draw bar clearance equal to 0.08 mm) to achieve a wet film 50 mm wide. 4. Hang or stand panels upright; allow to air dry 8 h at 23

10、 +/- 2 C or 30 minutes at 60 C. 5. Redraw over material film with clean applicator. Corrosion (Rust and Stain) 6. Place panels (with test surface face down) on condensing humidity unit maintained at 38 C and 100 % humidity for 72 h. A currently approved material may be used as control. Note: Test pa

Cleanability/Phosphatability 8. Rust-free panels shall be wiped with kerosene, washed and phosphated through assembl

13、y plant system. Include a clean steel panel as control. 9. Report evidence of unremoved drawing oil or compound on test panel, if present. 10. Evaluate control and test panels for zinc phosphate coating weight (FLTM AQ 101-02 and FLTM AQ 101-03), texture and appearance. Note: The coating weight of t

14、he test and the control panels should meet the applicable Engineering Specification and the texture and appearance of the test panel(s) should be equal to or better than that of the control panel. Procedure “B“ - Rust Preventative Oils 1. Lay steel panels horizontally on a flat surface over paper to
