ASTM D6278 PDF

Method Ball Rust Test Measures the ability of an engine oil to protect valve train components against rusting or corrosion under low temperature, short-trip service. Acidic corrosion results in wear, which can lead to component failure. The range is 1A the best and 4 the worst , 1B is typical. ISO Accredited. ASTM D Oxidation Characteristics This test attempts to determine the expected turbine oil life by subjecting the test oil to oxidative stress using oxygen, high temperatures, water and metal catalysts, all of which increase sludge and acid formation.

ASTM D Oxidation Characteristics This test attempts to determine the expected turbine oil life by subjecting the test oil to oxidative stress using oxygen, high temperatures, water and metal catalysts, all of which increase sludge and acid formation.

Test is complete when the sample acid number reaches 2. ASTM D Oxidation Stability, Bio-Diesel Fuel Test determines of the oxidation stability of fuels for diesel engines, by means of measuring the induction period of the fuel up to 48 hours. EN Oxidation Stability, Grease This test determines resistance of lubricating greases to oxidation when they are stored in an oxygen atmosphere in a sealed system at an elevated temperature.

Reported in minutes to a Test can also be run to a hard break for research purposes. Also formerly known as RBOT. ASTM D Rust Prevention D is available in 4 hour and 24 hour versions and can be run with distilled water and simulated seawater.

Measures the deposit-forming tendencies of an engine oil in the turbocharger at very high temperatures. Reported in milligrams of deposit. Measures the deposit-forming tendencies of an oil at piston ring-pack operating temperatures. Reported in minutes of resistance until the oxygen pressure falls sharply indicating the anti-oxidant has been overwhelmed or until the oil surpasses minutes without overwhelming the anti-oxidant.

After the air flow is stopped, the time required for the air entrained to release from the sample. It is used for specification of new oils and monitoring of in-service oils.

Under these circumstances, precipitates can form that impair the filterability of the oil the next time the engine is run. It simulates a problem that may be encountered in a new engine run for a short period of time, followed by a long period of storage with some water in the oil.

ASTM D Evaporation Loss, Grease Determination of the loss in mass by evaporation of lubricating greases and oils for applications where evaporation loss is a factor. Both the foaming tendency and stability of the foam are rated using Sequences I-IV and reported in mL and minutes, respectively. Measures percent oil volatilized during the test. ASTM D Phosphorus Emission Index Analysis of the volatilized oil to determine the amount of catalyst-contaminating phosphorus compounds volatilized with the oil.

Determines the milligrams of phosphorus volatilized per liter of the engine oil tested. Reported as an index value. Determines the milligrams of sulfur volatilized per liter of the engine oil tested. Useful test where only a sample amount of sample is available. ASTM D
