	SwRI offers the oxidation laboratory evaluation method, which determines the oxidation induction time of oil.

Oxidation laboratory evaluation method CEC L-85-T-99 is offered by Southwest Research Institute (SwRI) to determine the oxidation induction time of oil.
 

ACEA 2008 Specifications

The heavy-duty diesel engine oxidation test is part of ACEA 2008 Specifications:

• E4

• E6

• E7

• E9

CEC L-85-T-99 Test Parameters

A small quantity of oil is weighed into a sample pan and placed in a test cell. The cell is heated to a specified temperature and pressurized with air. The cell is held at a regulated temperature and pressure until an exothermic reaction occurs. The extra-polated onset time is measured and reported as the oxidation induction time.
 

Pass/Fail Criteria

Pass limits for oxidation induction time are ≥35 minutes.
