GB/T 12005.10-1992 specifies the method for determining the intrinsic viscosity of polyacrylamide (PAM) using the dilute solution viscosity method (typically with an Ubbelohde viscometer), and thereby calculating its average molecular weight. This is a classical method that indirectly characterizes the molecular weight of polymers through their hydrodynamic volume.
