Using glass hooks, dip and swirl the panels for not more than one s in the hydrobromic acid solution. Within one s dip the panels into a sample of t
6、he rust preventive at 23 +/- 2 C. Immerse and remove the panels 12 times over a period of 60 s in the rust preventive oil to assure that the panels are wetted thoroughly. 3. Hang the panels from glass hooks for 4 h at 23 +/- 2 C. 4. Examine and report any corrosion, staining or other corrosive attac
7、k occurring on the significant area of the panel as per the applicable Engineering Material Specification or Material Standard. Note: Do not evaluate the area 4 mm from the hole (used to hang the part) or the area 4 mm from the outside edge of the panel (refer to Figure 1). Chemicals, materials, par
