Pressed Steel HP100 - Special Considerations for Hydro?

[NJdiver85]

I am looking for information on any special considerations or guidelines for hydro testing HP PST-100 tanks (not the E-series). Specifically those guidelines that differ from Aluminum tanks. The issue is that I plan to have these tested in Bermuda, where the hyro facility sees mostly AL-80 like 99.9% of the time. They may have never tested an Pressed Steel HP-100 before. If there are some guidelines / testing procedures that I could present to the Hydro facility along with the tanks, I would feel a lot better.

I wish I could give you a link but there is a special procedure for doing a hydro on PST cylinders. It is not limited to HP pst's.

I'm pretty sure the link may break some rule, however it is the only source I found showing the PST hydro instructions.

Thanks! This is exactly what I was looking for.
