use of Williams-Landel-Ferry equation with Viton

use of Williams-Landel-Ferry equation with Viton

(OP)
I have a pressure test at temperature to validate an assembly.  the assembly uses both a Viton material and a fluorogreen material , depending on the temperature.   Normally we test at temperature and pressure and hold for twice the working time ( usually 72 hours working time).  I would like to use the Williams-Landel-Ferry equation to shorten my test time by increasing the temperature a bit.

Is there a website showing examples of the equation in use?  For Viton, the test temperature is 400F. for 72 hours.  Would like to test a a bit higher temp (ie, 425F) for a shorter time (maybe 4 hours) through superpositioning of the curve.  Thanks.

Have you considered some of the long list of results that Google gives out?
