This standard specifies a method for the detection of  substances  corrosive  to  metal  in lubricating grease under static conditions. The results do not necessarily correlate with greases operating under dynamic conditions.

NOTE 1 - As lubricating greases are employed under a diversity of conditions, it is not possible to specify either the  temperature  or  the  duration  of  the  test,  but  it  is recommended  that   the  test  temperature  be  not  higher than  20°C  below  the  drop  or  dropping-point  of  the sample.
