Immediately after weighing, place the watch glass and oil in the test jar and add 50.0 0.5 mL of
reagent water. Place the lid on the jar, then swirl the jar and contents vigorously for one minute.
Be careful to prevent any of the mixtures from splashing onto the inside surface of the jar lid.
Mount the steel panel on the Monel (TM) metal framework, place the panel in the jar and replace
the jar lid immediately. Mount the panel so that the polished side faces the center or the jar.
Maintain the temperature of the test unit at 25 3C for 10 to 15 minutes, place the unit in a
mechanical convection oven at 54 3C for 16 hours, then expose it for 6 hours at 4 3C,
followed by 18 hours at 54 3C. Position the jars in the oven so that the polished surface of the
panel is facing toward the direction of airflow. After the specified period examine the panels for
corrosion dots, disregarding any corrosion appearing within 6 mm of any edge, or any surface
stain that can be removed by absorbent tissue and naphtha. The panels shall exhibit a combined
total of not more than three corrosion dots, none of which exceed 1 mm in length, width or
diameter (see 3.3.2.2).
4.2.2.2.3 Corrosion protection (vapor phase after evaporation).
4.2.2.2.3.1 Test panels. Prepare three panels measuring 76 x 51 x 3.2 mm of the same
material and cleaned in the same manner as specified for the humidity cabinet test (see 4.2.2.2.1).
4.2.2.2.3.2 Polishing test panels. Polish the test panels in accordance with the procedure
specified for the vapor phase protection test (see 4.2.2.2.2.2).
4.2.2.2.3.3 Test apparatus. Use the test apparatus specified for the vapor phase
protection test (see 4.2.2.2.2.3).
4.2.2.2.3.4 Cleaning of apparatus before the test. Clean the test apparatus in accordance
with the procedure specified for the vapor phase protection test (see 4.2.2.2.2.4).
4.2.2.2.3.5 Test procedure. Evaluate a 15.00 0.05 g sample at 100 3C in accordance
with ASTM D972, except that the exposure period shall be 6 hours instead of the 22-hours
period specified. At the completion of the test, transfer the sample to a glass container, stopper
the container, and permit the sample to cool. Then evaluate the oil in accordance with the
procedure specified for the vapor phase protection test (see 4.2.2.2.2.5), using the quantity of oil
specified in Table IV.
