As part of an EEC Science Stimulation programme on extensional viscosity, two major conferences were organised on the subject. The second of these [1] was devoted to the results obtained on a standard fluid, Ml. The data obtained in shear flow was remarkably consistent from laboratory to laboratory. Extensional flow results presented quite a different picture. Using a series of nonequilibrium techniques such as the spinline rheometer, opposing jet, falling drop and converging flow, extensional viscosity results were obtained which differed by as much as 2 to 3 orders of magnitude. Nevertheless, it was apparent that consistency did exist within similar techniques. It is in the context of this information that the measurements described below have been made.
