include requirements for documenting brazier/brazing operator
qualification and criteria for brazed joint acceptance. The
applicant must make available the written brazing procedures and
destructive test records required for proof of brazier/brazing
involving heat or brazing should be accomplished in accordance
with approved written requirements and subjected to, as a
minimum, the tests and inspections specified for construction.
only for those brazed joints located between the chamber hull and
the first manually operated stop valve external to the chamber
hull. When ultrasonic testing or other nondestructive tests are
required on brazed joints within the SOC, the test records should
be made available to the SCA for review. All records should
clearly indicate that each joint has met the specification
requirements and must be signed by a qualified inspector.
3.3.5
Non-Destructive Testing. All nondestructive test (NDT)
records of welds performed within the SOC should be made
available to the SCA for review. All NDT records should clearly
indicate that each joint has satisfactorily met or exceeded the
specification requirements and must be signed by a qualified
inspector.
Assembly Procedures. Special procedures for assembly

of components and systems (e.g., torque specifications,
lubrication requirements, etc.,) should normally be called out in
technical manuals and on approved drawings. Where used, assembly
procedures should be issued prior to the start of production and
should be followed by personnel performing the work. All
assembly procedures to be used should be called out in the
fabrication/assembly procedure. When assembly procedures are
provided as drawing notes or technical manuals, the
fabrication/assembly procedure should call out the specific
paragraphs that apply. Assembly procedures should be verified as
completed by the person responsible for the work and these
records should be available for SCA review during the on-site
survey.
Cleaning Procedures. Where applicable, cleaning of
3.3.7
written cleaning procedures. Cleaning may be accomplished during
fabrication/assembly, upon final completion of assembly, or in a
combination of both, in accordance with the overall contamination
control process developed by the production activity or invoked
by the applicant. Cleaning procedures should include methods for
sampling and criteria for acceptance. Quantitative analysis to
verify system cleanliness must be performed prior to use of the
because hydrocarbons may be flammable. For guidance in cleaning
