.... Dynamic mechanical testing provides a quantity—called the complex viscosity ( µ *)—that has been shown by Cox and Merz 2 to equal the apparent viscosity ( µ a ) determined in steady-shear measurements. Yasuela et al. 3 recently confirmed this relationship with'a wide variety of instruments. Use...

... of a "foam viscosity" as measured in any standard viscometer. To explain this view, and to justify a more modest description in terms only of measurable quantities, we present a section on the rheological background of the problem.
