I am not doubting you on your information. I assume the value you cite is from a ASTM E-582 test. You cite the minimum ignition energy for methane as being .29 mJ. I have some questions based on the information contained in the standard. What was the test that produced that value? How many times were the test run? Were the results exactly the same each time. What was the concentration used in the test? Was there any variance in the concentration? If I were to have altered the concentration by .01% how much would that have changed the value, if any?
