The Vitamin D Standardization Program (VDSP) has collaborated with numerous groups and agencies to assemble a set of tools, i.e. a reference measurement system

Viscosity Measurements of R32 and R410A to 350 MPa

Author(s)
Arno D. Laesecke, Scott Bair
Viscosity measurements were performed with a falling cylinder viscometer on difluoromethane (R32) and the refrigerant blend R410A (R32+R125 with 50 % by mass)
