I missed to mention part number in message description. P/N: LMZ14202HEVAL. I would like to know the test environment (radiated/conducted emissions during no load/minimum load), length of Vout cable to load, Vin cable to the module.

There is some information about the testing shown in the data sheet curves. The kind of detailed information you are looking for may not be available, so long after the release of this product. As you know the EMI performance depends critically on the physical set-up of the test; the best way to determine the EMI performance in you application would be to test it in your environment. I will try to locate the engineer that took the measurements for the data in the app note, to try and answer some of you questions.
