Open a dialogue immediately with the Engineer/Surveyor responsible for periodic inspection of the installation for the purposes of burst and fire indemnity insurance.

You can find general guidance in ASME PCC-2 and this document:

http://www.hse.gov.uk/research/crr_pdf/1998/crr98168.pdf

And search this site (and others) for more general guidance, eg. ensure all air out of high points, .......

Check 49 CFR section 180. This is 2 times working pressure. Dry properly.
