to perform safely. This document describes the procedures and
criteria used by the SCA that must be followed by the applicant.
Sections 2 through 5 provide detailed information about the
certification process and the documentation required by the SCA.
Appendices A and B provide technical requirements that must be
met to successfully achieve certification. Appendix C provides
guidance for the required documentation. Glossary contains a
list of definitions. In hopes of achieving a more comprehensive
understanding, readers are encouraged to review these definitions
before proceeding with the remainder of the document.
1.4
Scope and Applicability. As stated previously, the
scope of this document includes unmanned pressure test facilities
used for testing and evaluation purposes or for unmanned medical
or physiological experiments. It also includes the associated
piping, mechanical, and electrical subsystems required to operate
these pressure vessels. It further ensures the safety of
operating personnel and the protection of property. Safety of
the objects or subjects being tested is not within the scope of
this document.
More specifically this document applies to pressure vessels of
the classes described in Tables 1 and 2. Examples include, but
are not limited to:
a) Pressure vessels used to subject test article(s) to a
simulated Deep Ocean Environment using a liquid
(incompressible) or gaseous (compressible) media
b) Pressure vessels that perform Medical Research using
compressible test media (air, helium, helium/oxygen,
hydrogen, hydrogen/oxygen, etc,)
c) Pressure vessels that perform helium soak (integrity)
testing of components that will later be subjected to a
Manned Hyperbaric Environment
Pressure vessels used for the storage of gases or liquids are
covered by other standards such as MIL-HDBK-1152, American
National Standards Institute (ANSI) NB-23, National Board
Inspection Code, or Department of Transportation (DOT)
specifications. Also, open tanks and towers used for testing
equipment are not within the scope of this document.
1.4.1
Unmanned Pressure Test Facility Classification
Criteria. Classification of the unmanned pressure test facility
should be determined as follows:
a) First, choose the appropriate classification with
regard to design pressure and size of the vessel in accordance
with Table 1.
b)
Secondly, review pressurization media of the test
