X-Ray Computed Tomography (XCT) System

AMENDMENT 1 - Please see attached "RFQ Questions" document for answers to questions recieved.  Due date for quotes has also been extended.THIS IS A COMBINED SYNOPSIS SOLICITATION FOR COMMERCIAL ITEMS PREPARED IN ACCORDANCE WITH THE FORMAT IN FAR SUBPART 12.6-STREAMLINED PROCEDURES FOR EVALUATION AND SOLICITATION FOR COMMERCIAL ITEMS-AS SUPPLEMENTED WITH ADDITIONAL INFORMATION INCLUDED IN THIS NOTICE. THIS ANNOUNCEMENT CONSTITUTES THE ONLY SOLICITATION; QUOTATIONS ARE BEING REQUESTED, AND A SEPARATE WRITTEN SOLICITATION DOCUMENT WILL NOT BE ISSUED. THE SOLICITATION IS BEING ISSUED USING SIMPLIFIED ACQUISITION PROCEDURES FOR CERTAIN COMMERCIAL ITEMS UNDER THE AUTHORITY OF FAR Part 13.Background: The Dimensional Metrology Group (DMG) and the Production Systems Group (PSG) at NIST require an industrial X-Ray computed tomography (XCT) system to be used for several different research and measurement purposes. The system will be used in the DMG development of error models that predict how

different errors in the XCT system, such as geometric misalignments of the components, manifest themselves in XCT measurement results. This would enable NIST to determine a set of test positions for use in performance evaluation standards (ISO 10360 series and ASME B89 series, in particular), which are adequately sensitive to known error sources. For this, NIST requires a system with hardware and software flexibility, especially in access to machine control and the reconstruction process. NIST will use an understanding of the effect of error sources on measurement results along with an error map that NIST generates of the system (using laser interferometry and other tools) to provide estimates of the uncertainty of measurements that are made using the system. This would allow NIST to eventually offer low-volume, specialized, measurement services (calibrations) using the CT system. Subsequently, NIST requires the lowest uncertainties possible. Measurement speed is generally not a concern.Protection and Encryption of Sensitive Data: To ensure secure, email communications, it is strongly recommended that all prospective offerors obtain email encryption capability. Use of unencrypted email by the submitter is done at the submitter’s own risk but will be accepted by the Contracting Officer. E-mails from the Contracting Officer may, at some point, be limited to prospective offerors with encryption capability.******************************Attachments:SpecificationsInstructions to OfferorsEvaluation CriteriaQuotation ChecklistProvisions and Clauses
