Evaluation of rust preventive characteristics
of automotive engine oils - Test method
(First revision)
1.1 This test method covers a Ball Rust Test (BRT) procedure
for evaluating the anti-rust ability of fluid lubricants. The
procedure is particularly suitable for the evaluation of automotive
engine oils under low-temperature, acidic service conditions.
1.2 Information Letters are published occasionally by the
ASTM Test Monitoring Center (TMC)2 to update this test
method. Copies of these letters can be obtained by writing the
center.
1.3 The values stated in SI units are to be regarded as
standard. No other units of measurement are included in this
standard.
1.3.1 Exceptions—Where there is no direct equivalent, such
as the units for screw threads, national pipe threads/diameters,
and tubing size.
1.4 This standard does not purport to address all of the
safety concerns, if any, associated with its use. It is the
responsibility of the user of this standard to establish appropriate
safety and health practices and determine the applicability
of regulatory limitations prior to use.
