NIST is conducting market research for a potential requirement to acquire a portable X-ray Diffraction system for multiaxial stress measurements on steel, with optional components for aluminum, liquid cooling, and spatial mapping. The system must be delivered to Gaithersburg, MD within 120 days after an order, with installation and training required on-site within 14 days of delivery. This is strictly a Request for Information to determine acquisition strategy and is not a solicitation.
