There is something called the Fligner-Killeen test, which has a bit of messy arithmetic but is nevertheless straightforward. It and numerous other tests for differences in variation (actually relative variation) are documented and carefully compared w.r.t. Type I and Type II error in:

Steven M. Donnelly and Andrew Kramer. 1999. "Testing for multiple species in fossil samples: An evaluation and comparison of tests for equal relative variation." American Journal of Physical Anthropology. 108: 507-529.
