1.1 This test method covers the procedure to determine the mass of deposit formed on a specially constructed test rod exposed to repetitive passage of 8.5 g of engine oil over the rod in a thin film under oxidative and catalytic conditions at 285 °C. The range of applicability of the Moderately High Temperature Thermo-Oxidation Engine Test (TEOST MHT2) test method as derived from an interlaboratory study is approximately 10 mg to 100 mg. However, experience indicates that deposit values from 1 mg to 150 mg or greater may be obtained.

1.2 This test method uses a patented instrument, method and patented, numbered, and registered depositor rods traceable to the manufacturer3 and made specifically for the practice and precision of the test method.4

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

1.3.1 Although not an SI unit, the special name liter (L) is allowed by SI for the cubic decimeter (dm3) and the milliliter (mL) for the SI cubic centimeter (cm3). Likewise, the special name millimeter (mm) is allowed by SI as a measurement of length.

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.
