摘要： An apparatus and method is shown for determining the pumpability limit, freeze point and/or pour point of liquids, particularly fuels, at sub-ambient temperatures. A sample is placed in a viscometer which viscometer is rapidly cooled by a chiller. During cooling, after some measurements of temperature and viscosity, further temperatures and viscosity are approximated using the least squares method, which temperature and viscosity are subsequently measured to determine the pumpability limit. Continuation of the method will also give the freeze point and pour point of the sample being tested.
