BS 2000-182:2006 Methods of test for petroleum and its products. Determination of inorganic acidity of petroleum products. Colour indicator titration method
This standard specifies a method for determining the water soluble inorganic (strong) acid content of used and unused lubricating oils, fuel oils, and petrolatum.
NOTE 1 - Oils containing additives that can be extracted
with water may give erroneous results.
NOTE 2 - The results may not be numerically identical with those obtained when other colour indicators or techniques are used.
