Standards can be obtained from appropriate standards authorities. ISO also uses Type 1C Ubbelohde viscometer, rather than the 1B, and reports viscosity number, rather than inherent viscosity. The RPV-2 software automatically calculates the Intrinsic Viscosity from each single determination using the Billmeyer equation. The time for the solution to flow from the upper to lower graduation marks is recorded.
