records required by the fabrication specifications and drawings
should be completed, signed, dated, and made available, as
appropriate, for review by the SCA.
The hazards associated with the performance requirements of an
unmanned pressure test facility dictate that only the highest
quality workmanship be acceptable. Consequently, the evaluation
of the workmanship evident in the finished system is a
significant factor in determining the acceptability of the
individual system. Acceptance standards to verify high quality
workmanship are available from both military and commercial
sources that establish acceptance/rejection criteria.
3.4.4
Cleanliness Control. The applicant should show that
the program for achieving and maintaining cleanliness of all
piping systems is under the close control of the builder during
and after system assembly.
The applicant should use only SCA approved cleaning procedures
during and after system fabrication. Failure to keep these
systems clean may cause serious injury or death to the system
operators. Appendix B provides additional guidance concerning
cleanliness control of unmanned pressure test facilities.
Once a system is verified clean within acceptable limits, no re-
entry is allowed into that system without strict adherence to re-
entry controls. Any uncontrolled opening of an unmanned pressure
test facility to the surrounding atmosphere may require re-
cleaning of the entire system to re-establish system cleanliness.
The final levels of cleanliness should meet the requirements that
have been specified and justified by the applicant and that have
been accepted by the SCA. Records of the date, method and
results of sampling should be kept and made available to the SCA
for review. Documentation of system cleanliness should include
cleaning sheets and sketches and should indicate that each
component, section or subsection of a system has been
satisfactorily cleaned and that the entire system is free of
Testing and Inspection Control. The applicant should
3.4.5
show that there is an effective test and inspection system in
place. The system must establish the inspections and tests
necessary to substantiate that items within the SOC are in
conformance with the specified requirements. All inspection and
test requirements should be identified in the
fabrication/assembly procedures. The inspection system should
incorporate clear, complete, and current instructions for
inspection and should include criteria for acceptance and
rejection. Records of all inspections and tests should be
maintained and should indicate the nature and number of
observations made the number and type of deficiencies found and
the nature of the corrective action taken. Where no deficiencies
are found, the satisfactory condition should be noted. All test
and inspection documents should clearly show the following as a
