Standard Test Method for Calculation of Viscosity-Gravity Constant (VGC) of Petroleum Oils
|Publication Date:||1 June 2014|
|ICS Code (Petroleum products in general):||75.080|
This test method covers the calculation of the viscositygravity constant (VGC) of petroleum oils2 having viscosities in excess of 5.5 mm2/s at 40°C (104°F) and in excess of 0.8 mm2/s at 100°C (212°F).
Annex A1 describes a method for calculating the VGC from Saybolt (SUS) viscosity and relative density.
The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
The SI unit of kinematic viscosity is mm2/s.
Exception-Fahrenheit temperature units are used in this practice because they are accepted by industry for the type of legacy conversions described in this practice.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
