ASTM D6557-10
(Test Method)Standard Test Method for Evaluation of Rust Preventive Characteristics of Automotive Engine Oils
Standard Test Method for Evaluation of Rust Preventive Characteristics of Automotive Engine Oils
SIGNIFICANCE AND USE
This bench test method was designed as a replacement for Test Method D5844. Test Method D5844 was designed to measure the ability of an engine oil to protect valve train components against rusting or corrosion under low temperature, short-trip service, and was correlated with vehicles in that type of service prior to 1978.
Correlation between these two test methods has been demonstrated for most, but not all, of the test oils evaluated.
SCOPE
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) 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. See 7.1.1-7.1.3 and 8.2.1.1.
