- Standard: TDS 679-2018
- Kinematic viscosity at 40 °C: 29.0–35.0 mm²/s (Turbo 32) · 41–51 mm²/s (Turbo 46)
- Viscosity index: min 95, both grades
- Demulsification number: max 180 s (Turbo 32) · max 210 s (Turbo 46)
- Mechanical impurities and corrosion on steel rods: none, both grades
Grades
Türkmen Turbo 32
ISO VG 32. Kinematic viscosity at 40 °C 29.0–35.0 mm²/s and at 50 °C 20.0–23.0 mm²/s, flash point (open cup) min 190 °C, pour point max −15 °C, acid number max 0.05 mg KOH/g, sulfur max 0.5%, colour ASTM max 1.0. The lighter grade, and the tighter specification on acidity, oxidation sludge and demulsification.
Türkmen Turbo 46
ISO VG 46. Kinematic viscosity at 40 °C 41–51 mm²/s, flash point (open cup) min 195 °C, pour point max −10 °C, acid number max 0.5 mg KOH/g, sulfur max 0.8%, colour ASTM max 2.0. Specified where a heavier turbine oil is called for.
