1. PURPOSE

The Cryogenic High-power Integrated Low Loss Motor Demonstration (CHILL) project at NASA Glenn Research Center (GRC) in Cleveland, OH is currently building the Testbed for High Energy cRyogenic Materials And Superconductors (THERMAS) at Building 191 to test materials and components for future high-power, superconducting aircraft powertrains. This facility will accommodate a large cryogenic helium refrigeration system that is housed inside a 40-foot shipping container. This container will be located outside Building 191, with vacuum-jacketed supply and return lines rounded into the test cell and connecting the refrigerator to the test hardware. This Statement of Work (SOW) defines the requirements for procurement of these lines.

2. The Contractor shall deliver one (1) vacuum operator assembly that is compatible with all pump-out ports supplied on each piping spool.

3. The Contractor shall provide an Acceptance Data Package (ADP) that contains all correspondence between the Contractor and NASA; quality control documents; as-built engineering drawings of the piping assemblies; engineering analyses; a signed Certificate of Conformance to ASME B31.3 for all assemblies/components; cleanliness, vacuum retention, and helium mass spec compliance; material certifications, final acceptance inspection records; and any other documentation required to administer the successful completion of the contract.

The test report will list the specifications, including revision numbers or letters, to which the material has been tested and/or inspected and the identification of the material lot to which it applies.

When the material specification requires quantitative limits for chemical, mechanical, or physical properties, the test report will contain the actual test and/or inspection values obtained. For aluminum mill products (except castings), certifications for chemistry may indicate compliance within the allowed range. Certifications for physical properties will show actual values.

When contractor supplies converted material produced by a raw material manufacturer, the contractor shall submit all pre and post conversion chemical/physical tests reports.

8.4.3 AQC08 Special Process Certification

Special processes shall be performed only by sources that have been surveyed and qualified/approved, by the supplier and/or the Customer, to perform those processes.

Unless otherwise specified in the contract, the Contractor may utilize independent inspection and testing laboratories or services that are acceptable to the Government.

8.5.6 Q39 Objective Evidence of Dimensional Inspection

The Contractor shall provide objective evidence with each shipment that all the articles were dimensionally inspected for conformance with drawing and Delivery Order requirements.

Objective evidence shall consist of records of actual dimensional readings taken during inspections, of each part, with the dimension and its tolerance noted. All out of tolerance measurements shall be clearly identified on the records, and the disposition of that part noted by the Organizations quality assurance organization. This information is to be submitted to NASA for acceptance/rejection of the out-of-tolerance condition, prior to submittal of the hardware.

Organization shall identify each inspection data sheet to the related Contract/Purchase Order, part number, revision and when applicable, serial number. The management representative responsible for the Contractor’s inspection activity, will certify that with signer’s title and date of signature indicated that all of the shipped parts were indeed inspected to the criteria specified and those actual measurements are the ones provided. If serial numbers are not assigned, then the supplier shall devise a method of linking the record of dimensional measurements with the specific part measured (e.g., taped, bagged together). Inspection equipment (e.g., tools, gages) used during dimensional measurement shall have its identification numbering recorded and have the ability to recall the parts inspected with that particular inspection device in the event it is subsequently found to be significantly out of tolerance.
