Rule 702 sets forth the overarching requirement of reliability, and an analysis of the sufficiency of the expert's basis cannot be divorced from the ultimate reliability of the expert's opinion. In contrast, the "reasonable reliance" requirement of Rule 703 is a relatively narrow inquiry.

The testing procedure worked relatively well in both instances. The testing of the single valve (higher pressure) was more easily accomplished due to the simplicity of the testing procedure. Only a single valve was being tested and isolation was accomplished with blinds rather than double block and bleed valving.

He should use FCI 70-2 for seat leakage tests, for the simple reason that API 598 / API 6D allowable leakages are meant for shut-off valves, therefore much more restrictive than FCI 70-2. Control valves are meant for control, not shut-off. As for the shell test, it's ok to use API 598 / API 6D, since FCI 70-2 doesn't cover such tests.
