In the event the component cannot be restored to "as new"
condition, an in-kind replacement for the required component
should be installed. The in-kind replacement must pass all the
performed and documented. NAVFAC MO-406 may be used as a guide.
In-kind replacement of a component is defined as replacement
with an identical component if that component is still
manufactured. In the event an identical component is no longer
manufactured, the replacement component must meet all of the
original component's design criteria. Should there be any doubt
as to whether a component is an in-kind replacement, contact the
HAZCAT II Systems. All HAZCAT II systems should be
envelope functionally tested to their complete design parameters.
Envelope functional testing is defined as testing each component
of the respective HAZCAT II system to its system design
parameters (i.e., ball valves, completely shut off and fully
open; needle valve, fine tuned and flow as required for original
system was installed, should be conducted for all HAZCAT II
systems. HAZCAT II system components should not be removed or
refurbished, unless the component does not perform or if a
noticeable flaw is found during functional testing of the system.
performed and documented, NAVFAC MO-406 may be used as a guide.
HAZCAT III and IV Systems. All HAZCAT III and IV
systems should be demonstration tested to system design
level performed originally when the system was installed. HAZCAT
III and IV system components should not be removed or refurbished
unless the component does not perform, or if a noticeable flaw is
found during demonstration testing of the system. General
maintenance of all HAZCAT III and IV system components should be
performed and documented, NAVFAC MO-406 may be used as a guide
Routine Maintenance. As defined in Section 2, all
HAZCAT I, II, III AND IV system components should receive routine
maintenance as required by facilities PMS or as required by the
manufacturer of the respective component. General maintenance
should include, but is not limited to: replacement of belts,
pulleys, lubrication, filters, calibration, o-rings, calibration
of gauges, periodic testing of relief devices, replacement of
Document Control. The requirement for adequate
re-certification as it is in the initial certification process.
