Full Description

1.1''This test method is used to evaluate the sludging tendencies of steam and gas turbine lubricants during the oxidation process in the presence of oxygen and metal catalyst (copper and iron) at an elevated temperature. This test method may be used to evaluate industrial oils (for example, circulating oils and so forth).

1.2''This test method is a modification of Test Method D4310 where the sludging and corrosion tendencies of the same kinds of oils are determined after 1000'''h at 95'''''C in the presence of water. Water is omitted in this modification.

1.3''The values stated in SI units are to be regarded as standard.

1.3.1''Exception'''The values in parentheses in some of the figures are provided for information only for those using old equipment based on non-SI units.
