I think it's good practice to "explore" your product somewhat before you go for compliance testing. It helps determine just what you need to quantify in the test lab, and what can be ignored. I have not yet met with problems going this route with any agency folks, in fact I would expect them to endorse it. Our lab makes its living helping folks make these decisions before they go to a DLS, Elite, UL etc where the charges are much higher, but the labs are certified.
