How to test an unmarked capacitor?


Is it possible to test an unmarked capacitor for "uf" and "vdc" specifications using a hand held fluke meter?

Assuming that "fluke meter" refers to a multimeter/vom (volt-ohm-milliameter), the answer is no. You need a capacitance meter to measure uf. And I doubt that it is practical to test for the voltage rating by any means. You would have to raise the applied voltage to the point where leakage current started rising excessively, which could very conceivably inflict permanent damage.
