TEOST® Trident

Thermo-Oxidation Engine Oil Simulation Test

Test Methods

  • ASTM D6335 | 33C
    (Chinese SH/T0750)
  • ASTM D7097 | MHT®
    (Moderately High Temperature)
  • ASTM D8447 | TEOST Turbo®

Principle

The three current TEOST® tests operate under temperatures and environmental conditions identified as significant in internal combustion engines to simulate the oxidation and deposit-forming tendencies of engine oils. Oil samples, treated with catalyst, are pumped over a heated steel Depositor Rod on which deposits form. The weight of the Depositor Rod after the test is subtracted from its pre-test weight and added to the particulate weight collected by filtering the remaining oil. The results are reported in milligrams. 

BROCHURE

Features & Benefits

  • Adjustable temperature zones and pump speeds.
  • Clear Glass Mantle with MHT® and Turbo® tests for easy viewing of depositor area during the test.
  • Ability to collect the volatilized material for further analysis and investigation.
