The rules say,

"Custom made components, or parts operating above the suppliers maximum working pressure, must beindependently tested and certified at 120% of the maximum system pressure available at that point."

Please can someone tell me of a person/organisation who can provide this service. I have a full CO2 pressure ram that needs certifying. I also need to know the pressure to which it needs testing. As I will have a 1000psig bursting disc, this would seem to be a sensible test pressure. It is also about 120% of the likely maximum system pressure. I am happy to be guided by others.
