Particle Size Distribution Analysis

This contract specifies specialized testing services to validate the particle size distribution and Hall Flow characteristics of metal powder, with strict criteria requiring the d90 to be no greater than 50 micrometers and the d10 to be no less than 18 micrometers. The work involves precise analytical methods to ensure the powder meets defined specifications critical for aerospace applications, particularly in additive manufacturing or propulsion systems where consistency in particle morphology directly impacts performance and safety. The testing must be performed under standardized protocols to deliver reliable, repeatable data that can be used for quality control and regulatory compliance. The contract is a subcontract categorized as a Total Small Business Set-Aside under the SBA program, meaning only small businesses are eligible to compete, and it is classified under NAICS code 541380 for other scientific and technical consulting services. It is issued by the NASA Shared Services Center on behalf of the National Aeronautics and Space Administration, reflecting its alignment with NASA’s supply chain requirements for advanced materials. The solicitation was posted on May 12, 2026, with a response deadline of May 19, 2026, at 7:00 PM, indicating a tight turnaround window for interested parties to submit proposals. The place of performance and point of contact details are not specified, suggesting deliverables may be delivered remotely or at the contractor’s facility, with final validation data submitted electronically.
