4.7 TESTING AND INSPECTION QUALITY CONTROL
Test Plan. A test plan shall be developed for the
facility which clearly defines all required testing within the
certified boundaries. This test plan shall include as a minimum:
Test criteria requirements.
Test frequencies and requirements for conducting (e.g.,
initial installation, annually, after repairs, etc.).
c . Flow diagram similar to Figure 4-3, which shows all tests
required in support of certification.
d . Test and inspection procedures index.
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
ASME Boiler and Pressure Vessel Code (Section VIII,
Divisions I and II).
ANSI/NB-23, National Board Inspection Code.
NFPA National Fire Codes (See Appendix A for applicable
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:
When initially installed.
When moved and reinstalled.
At two-year intervals at a given location.
Piping Systems (Strength, Leak and Operational).
