Antirust Properties of Petroleum Products by NACE Corrosion 1
Protective gloves should be worn throughout testing. 2
Clean beakers with detergent rinsing thoroughly with DI water prior to drying in oven at 100°F. 3
Stirrers and beaker covers are cleaned using isooctane, followed by DI water, then dried using lint-less cloth. 4
Ensure bath temperature is 100±2°F (reading is taken from ASTM thermometer located at rear of bath cover). 5
Add 300 mL sample to beaker(s). 6
Place beaker(s) in oil bath ensuring that bath oil level is not below fuel level in test beaker. 7
Place stirrer(s) through appropriate opening in plastic cover and place cover(s) on beaker(s). 8
Rotate beaker(s) so that baffles are 90 degrees from test specimen hole. 9
Start the stirrers and allow approximately 30 minutes for sample(s) to reach 100±2°F. 10
Clean test specimen with acetone – test specimen must not be touched with bare hands at any time after cleaning. 11
Mount test specimen on grinding chuck and tighten firmly.
CAUTION: Test specimen may rotate during polishing causing it to fall off chuck. Close attention should be paid to test specimen and fingers or any loose clothing, hair, badge lanyards, etc. to ensure no entanglement occurs. Stand to side of chuck while apparatus is rotating. 12
Apply abrasive cloth to test specimen and continue grinding until any rust or irregularities are removed. 13
Final polishing is performed using a new piece of abrasive cloth and is performed immediately prior to running test.

NOTE: Test specimens may be stored in isooctane after preliminary grinding but prior to final polishing. 14
Attach test specimen to holder then rinse with toluene followed by acetone. 15
Perform final rinse of test specimen with isooctane and immediately insert test specimen assembly through hole in beaker cover. 16
Allow sample(s) to stir for 30 minutes then, with stirrers still rotating, add 30 mL distilled water, using a long-necked funnel, into the bottom of the beaker. 17
Continue stirring sample(s) for 3.5 hours then turn off stirrers and remove beaker(s). 18
Remove test specimen(s) and rinse with toluene followed by acetone. 19
Rate test specimen using 2x lighted magnifying glass according to the following table:
Rating Percent of Test Surface Corrosion A
B Less than 0.1 (2 or 3 spots, no more than 1 mm diameter)
B Less than 5
B – 25
C – 50
D – 75
E – 100
