 System Certification Scone.
The next step in the
4.2.3
certification process is the development of a certification scope,
The scope,
or scope of certification (SOC), for the system.
developed by the sponsor and command, is a list of those subsystems
required to ensure the safety and well-being of the system
occupants and divers. Systems which pertain to diving systems and
hyperbaric complexes are defined in Chapter 2 of SS521-AA-MAN-010.
The scope also includes a list of the operating, emergency,
and maintenance procedures for those subsystems, as well as any
emergency or back-up systems required to rescue and return the
occupants to safety after a noncatastrophic accident. In addition,
the scope should include the criteria and justification for
establishing the limits of the certification scope.
The sponsor
must look at each of the systems within his facility and evaluate
the effects of specific failure which could occur during a mission.
The SCA will provide assistance if the sponsor is not sure whether
a system should be included within the scope.
There is no rigid
format for presenting the scope, however, the SOC usually includes
a list of subsystems with detailed descriptions and a system
schematic (or drawings) that clearly show the boundaries of the
system that are within the scope. The most important consideration
is that the certification scope be clearly and explicitly defined.
The sponsor should submit the scope to the NAVFAC SCA for review
and approval.
Maintenance of Certification Documentation.
4.2.4
When
the certification scope and the PSOB have been approved, the
sponsor shall assemble the documentation necessary to support the
request for certification or recertification.
SS521-AA-MAN-010

there are many diving and chamber systems in service that predate

in addition to those listed above that provides information as to
the replacement of components, repair of a component, and the
operating and testing of components/systems should also go into
the sponsor's file of certification documentation.
The sponsors of newly developed and constructed diving and
chamber systems must provide the documentation required by SS521-
AA-MAN-010.
