ASTM D2649 Test Method for Corrosion Characteristics of Solid Film Lubricants
9. Procedure
9.1 Arrange the panels (see Fig. 1) by placing a coated panel against an uncoated panel at a 90-° angle to each other; place them between the aluminum channel, insert the bolts, and tighten the nut and bolt combination to a constant load of 2.8 N•m (25 lb•in.) using a torque wrench.
9.2 Run a blank assembly with uncoated panels concomitantly with each set of samples as a check on the whole process of panel preparation.
9.3 If it is planned to make inspections prior to the completion of the normal 500-h period, prepare additional assemblies so that no reassembly will be required.
9.4 Place the assembly in a preheated oven at 65.6 +/- 4°C (150 +/- 8°F) for 2 h.
9.5 Remove the assembly after 2 h and immediately place the assembly into the humidity cabinet at 49 +/- 3°C (120 +/- 5°F), 95 +/- 3 % relative humidity.
NOTE 2 - Assemblies may be placed in the cabinet in any suitable way to avoid interference with each other and drippage of condensate. Hanging from the rotor is permissible but not specifically recommended.
9.6 Disassemble and inspect the coated and uncoated contact surfaces at 500 h unless some other test period is specifically required.
