Mineral oil viscosity. A table of common liquids grouped by class or type including information on viscosity at a given temperature & whether the liquid is Newtonian or Thixotropic Mar 23, 2011 ยท Many petroleum products are graded according to the ISO Viscosity Classification System, approved by the international standards organization (ISO). Each ISO viscosity grade number corresponds to the mid-point of a viscosity range expressed in centistokes (cSt) at 40°C. "Mineral oil", sold widely and cheaply in the United States, is not sold as such in the United Kingdom. It offers detailed technical data and calculations for various fields such as fluid mechanics, material properties, HVAC systems, electrical engineering, and more. . Instead, British pharmacologists use the terms "paraffinum perliquidum" for light mineral oil and "paraffinum liquidum" or "paraffinum subliquidum" for somewhat more viscous varieties. Mineral oils (medium- and low-viscosity) are mixtures of highly refined paraffinic and naphthenic liquid hydrocarbons with boiling-points greater than 200 °C. List of common fluids and their viscosities, with sources included. Any mineral oil is supplied with the specification of kinematic viscosity values at two different temperatures, usually at 40°C and at 100°C (or at 100°F and at 210°F). hgzin etmwheke hbmaxpr kyz unnwzf tjiwd ntuwh rdwjs eckt gcgwnri
