Description

1.1 This test method covers the calculation of the viscosity-gravity constant (VGC) of petroleum oils having viscosities in excess of 4 cSt. = 4 X 10-6 m-2/s at 40&degC (104&degF).

1.2 Annex A1 describes a method for calculating the VGC from Saybolt (SUS) viscosity and relative density.

1.3 This standard does not purport to address all of the safety problems, 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.>

1.4 The values stated in either acceptable SI units or in other units shall be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining values in any way.
