Note! Viscosity conversions are based on fluids with specific gravity of one. SpectraSyn 100 Polyalphaolefin (PAO) Fluid Product Description SpectraSyn High Viscosity Polyalphaolefin (PAO) basestocks feature low temperature properties (pour point and viscosity), low volatility, and improved thermal stability. Compressor oils Learn More > CETUS HIPERSYN ISO 32,46, 68, 100, 150, 220, 320. Check ASTM D 2161 "Standard Practice for Conversion of Kinematic Viscosity to Saybolt Universal Viscosity or to Saybolt Furol Viscosity"Ģ) Water at 68.4 oF (20.2 oC) has an absolute viscosity of one - 1 - centiPoise. CENTIPO ISE 1.00 2.00 3.00 5.00 7.50 10.0 15.0 20.0 25.0 30.0 40.0 50.0 60.0 70.0 80.0 90. The viscosity in centiStokes at 100C and the viscosity index. For example, a lubricant with an ISO grade of 32 has a viscosity within the range of 28.8-35.2, the midpoint of which is 32.1) The Saybolt Universal SUS viscosity equivalent (SSU or SUS) to a given kinematic viscosity varies with the temperature at which the determination is made. The term viscosity refers to the thickness or flow-ability of a liquid. Everyone involved in lubrications has a viscosity equivalents chart but does anyone know how they went about lining up the Kinematic Viscosity (in cSt) 40. Use this calculator to find the viscosity in centiStokes of an oil at a temperature of 40C. Each ISO viscosity grade number corresponds to the mid-point of a viscosity range expressed in centistokes(cSt) at 40☌. Many petroleum products are graded according to the ISO Viscosity Classification System, approved by the international standards organization (ISO). SAE 90 to 250 and 20 to 50 specified at 100☌. Viscosities based on 96 VI single grade oils.Įquivalent viscosities for 100° & 210☏ are shown Viscosities can be related horizontally only A more familiar viscosity term is kinematic viscosity, which takes into account the fluid density as a quotient of the fluid’s dynamic viscosity and is usually reported in stokes (St) or centistokes (1 St 100 cSt). The diagram below indicates the minimum and maximum viscosities in centistokes for equivalent ISO-VG grades at temperature 40 o C. an ISO grade 32 has a viscosity within the range ot 28.8 352, the midpoint ot which is 32.
