Statistics work as impressive as ever. Two questions Alex;
What specific legal requirement are you referring to in the first statement, curious.
The reference to He & CO2 increasing the possibility of a tox, have you found much tangible evidence to get some conclusions from on this? Any suppositions you might want to share?
On your first question, EN14143:2003 makes it a requirement to meet EN 61508. That contains the 1 billion hour requirement in part 0.
On the second item, it is in the papers we cited in the pdf I posted. The reference section has links to the papers online, so it easy to download them.
We also kept our list of citations down to the minimum so we do not lose the important information in noise. The papers we cited have a good list of other references on this same topic.
Cheers,
Alex
