薄膜氧吸收试验仪（TFOUT）
Passenger-car engine oil QC and treat-rate optimisation call for an oxidation test that is quicker than full engine runs. TFOUT puts 1.5 ± 0.01 g in a vessel charged to 620 kPa oxygen at 160 ± 0.2 °C, rotating at 100 ± 5 rpm until pressure drops 175 kPa. Tests last about 50–300 min; choose 1–4 positions.
