I developed a modern system to replace hardware and supplies that are no longer available that are used used to certify the breathing apparatus used by fire fighters.
Using the old standard using a superior measurement the most popular industry standard failed.
Since the new standard had to be approved by a board of interested parties... including the industry standard group. Not something the government people wanted to do.
I offered an alternative that tweaked the rules to forgive the issues with the industry standard. It was accepted.
That certification lab heavily funded by lobbying by the industry standard.
That is my story and I am sticking with it.
