Section 5:
REPAIR AND OVERHAUL
5.1
Introduction. Periodically, unmanned pressure test
facilities require repair or overhaul wherein industrial work is
performed within the certification boundary beyond that which is
normally conducted during routine maintenance procedures. During
such industrial periods, system certification should be
terminated until the requirements for re-certification, specified
in Section 2, have been satisfied.
During significant configuration changes, the responsibilities of
the acquisition manager may shift from the user command to
another command or program office. However, the user command to
which the system is assigned should remain the applicant for
system certification. Close coordination between the acquisition
manager, the applicant and the SCA is crucial to ensure that the
system certification process does not become disjointed and
unmanageable.
In all instances, the number and extent of technical design
reviews should be negotiated between the applicant and the SCA.
It is the responsibility of the system applicant to ensure that
the requirements for re-certification are satisfied during repair
or overhaul periods. As stated in Section 1, the line of
communication concerning certification is between the SCA and the
system applicant and not between the SCA and the activity
responsible for the performance of the work. The applicant may
designate an individual or organization to act as certification
manager, who will be the single point of contact for liaison both
with the overhaul organization and with the SCA on matters
concerning certification.
5.2
Certification Status During Repair Or Overhaul. When
the supporting building facilities undergo any major facility
upgrade that would affect the performance or operational
integrity of the unmanned pressure test facility, system
certification is terminated.
Often, component or minor system repair is required between
scheduled overhauls. Minor work on the facility that does not
involve hot work (welding/brazing) and that does not modify the
certified system configuration does not terminate system
certification if the work and testing are documented under re-
entry control. Though notification to the SCA is not required,
all documentation of the minor work and testing will be reviewed
at the next certification on-site survey. Examples of minor work
that does not terminate or suspend system certification are:
a)
Repairing leaking valves by replacing valve
software
b) Replacing unmanned pressure test facility
components (mechanical joints) with the same kind as specified by
51
