Without digging up the references. They are tanks in the carbon fiber group that because of some regestry listing says only the manufacturer or a certified PSI inspector can do a valid visdual inspection on them.
Let me add one more thing. A big portion of the PSI thing is that when complying with thier practices you are to some degree pretected from suit. If a carbon tank blows and it is found that it was not inspected by wither the manufacturer or a PSI inspector it is considered as not being inspected at all. I am not sure if that applies to ALL forms of CF tanks but certainly some of them it does. So by virtue of this reg being placed in the federal registry it is LAW that only a manufactorer or PSI inspection is valid.
