95 -- WHITE CAST IRON SOL 53SBNB967071 DUE 061699 POC Joan M. Smith, Contracting Officer, (301) 975-6458, or Anne McFarlane, Contract Specialist, Tel (301) 975-4648, FAX (301) 963-7732, e-mail anne.mcfarlane@nist.gov WEB: NIST Contracts Homepage, http://www.nist.gov/admin/od/contract/contract.htm. E-MAIL: NIST Contracts Office, Contract@nist.gov. The National Institute of Standards and Technology (NIST) intends to negotiate with Sangre Specialty Materials for NIST reference materials by chill casting. SRMs C1146a and C1150a White Cast Irons and C2425a Ductile Iron are required for instrument calibration standards. Previous standards produced by hot isotstatic pressing to replace the chill cast materials have been unsatisfactory because the instrument responses of the two types of materials are too dissimilar. Sangre Specialty Materials is the only known source that can produce chill cast materials to NIST specifications. Sangre Specialty Materials has the equipment and experience to make chill cast specimens for the "b" renewals that NIST requires, and is the only known source of chill cast materials. The required delivery is 90 days after receipt of order, FOB Destination, Gaithersburg, MD. The statutory authority is 41USC 254 (c)(1), only one responsible source that can meet the requirements of the Government. The proposed contract action is for supplies or services for which the Government intends to solicit and negotiate with only one source under the authority of FAR 6.302. Interested persons may identify their interest and capability to respond to the requirement or submit proposals to NIST, Attn: Anne McFarlane, Building 301, Room B117, 100 Bureau Drive Stop 3572, Gaithersburg, MD 20899-3572. This notice of intent is not a request for competitive proposals. However, all proposals received by 3:00 PM Eastern Time June 16, 1999, will be considered by the Government. A determination by the Government not to compete this proposed contract based upon responses to this notice is solely within the discretion of the Contracting Officer. Posted 06/02/99 (W-SN337934).
