4.7.2
Test Criteria and Requirements
a.  Hyperbaric Facility Support Pressure Vessels (Strength,
Leak and Operational).
The primary guidance document for test
criteria  and  requirements  for  pressure  vessels  is  provided  by
NAVFAC MO-324, Inspection and Certification of Boilers and Unfired
Pressure Vessels.  By definition, pressure vessels include manned
chambers  and  all  hyperbaric  facility  support  pressure  vessels
(e.g., flasks, filters, separators, etc.) with an internal diameter
of three inches or greater.  NAVFAC MO-324 references the following
codes for the conduct of inspection and testing of unfired pressure
vessels:
o
ASME  Boiler  and  Pressure  Vessel  Code  (Section  VIII,
Divisions I and II).
o
ANSI/NB-23, National Board Inspection Code.
o
NFPA National Fire Codes (See Appendix A for applicable
NFPA codes).
When there is a conflict between NAVFAC MO-324 and any of the
above codes, NAVFAC MO-324 shall govern.
Additionally, the U.S.
Navy Diving Manual (Volume I, Appendix D) requires a pressure test
on every U.S. Navy recompression chamber as follows:
o
When initially installed.
o
When moved and reinstalled.
o
At two-year intervals at a given location.
b.
Piping Systems (Strength, Leak and Operational).
The
guidance document for test criteria and requirements for piping
These  criteria  and
systems is ANSI/ASME B31.1, Power Piping.
requirements apply to:
