use of Williams-Landel-Ferry equation with Viton

[awol]

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.
