BSA and/or their representative shall have the option to witness all the tests defined in this SOW.

4.7 Test and inspection procedures

Test and inspection procedures (e.g. leak and pressure test) required to demonstrate satisfactory completion of requirements shall be prepared by the contractor and submitted to BSA for approval sixty (60) days prior to use of such procedures. BSA reserves the right to modify the tests or to require any additional test procedures or details deemed necessary to determine compliance with the requirements of this SOW and CAD-Spec-1365. Once approved, changes/revisions shall be approved by the BSA technical representative prior to implementation.

4.8 Weld inspection

For the helium vessel a weld inspection traveler shall be submitted as part of the documentation for the ASME BPVC vessel documentation.

4.9 Test Records

Test records shall be prepared and maintained for all tests herein. Records shall show test dates, test conditions, test equipment/instrumentation/gages identification (name, model/part number, serial number), test pressures, test durations, leakage rates, and other system characteristics.

Test records shall be well organized and shall clearly and uniquely identify each test record to the specific item tested, and its final installed location. For this reason, drawings shall be included in test records, with each piping/tubing assembly systematically and uniquely identified.

4.10 Failure Reporting, Analysis and Corrective Action

The contractor shall maintain a failure reporting, analysis, and corrective action program throughout the fabrication and testing process. Any failure or non-conformance of a unit found during the acceptance tests shall be communicated to the BSA technical representative with a non-conformance report. All corrective action of the failure or non-conformance unit shall be approved by the BSA technical representative. The BSA technical representative shall be notified of any drawing changes.

4.11 Rework and Repairs

If failures occur or repairs are required to an assembly or any component during manufacturing or testing that affects form, fit, function, reliability, safety, or interchangeability, the process shall stop and BSA shall be immediately notified. BSA at their discretion may ask for retesting, additional review and evaluation to determine root causes, analyses of failure modes(s) or proposals for repair. Proposals for repair shall include adequate information for evaluating the repair, testing the effectiveness of repair, and methods to prevent damage to the existing work. No proposed repair shall be initiated without the approval of the BSA technical representative. No repair shall be considered successfully accomplished without inspection and written approval by BSA. All repairs shall be at the expense of the Contractor.
