Description

ASTM D8447-22e1

Active Standard: Standard Test Method for Determination of Turbo Charger Deposits by Thermo-Oxidation Engine Oil Simulation Test

ASTM D8447

Scope

1.1 This test method covers the procedure to determine the amount of deposits formed by automotive engine oils utilizing the thermo-oxidation engine oil simulation test (TEOST2).3 The range and applicability of the TEOST Turbo2 test method as derived from an interlaboratory study is approximately 5 mg to 90 mg. However, experience indicates that deposit levels of up to 150 mg or greater can be obtained.

1.2 This test method uses a patented instrument, method and patented, numbered, and registered depositor rods traceable to the manufacturer4 and made specifically for the practice and precision of the test method.

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 Milligrams (mg), grams (g), milliliters (mL), and liters (L) are the units provided because they are an industry accepted standard.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
