Particle Size Distribution (PSD) Analysis & Certification

The contract requires comprehensive particle size distribution analysis of ORCAlloy-21 powder using ASTM B214 sieve analysis and ASTM B822 light scattering methods to ensure compliance with strict size specifications: D10 must exceed 15 micrometers, D50 must remain below 45 micrometers, and D90 must not surpass 85 micrometers. These tests are critical for verifying the powder’s suitability for specialized applications, likely in aerospace or advanced manufacturing, where consistent particle size directly impacts performance and reliability. The analysis must be performed in accordance with established ASTM standards and the results must be formally certified to demonstrate conformance. Issued by the NASA Shared Services Center under the NAICS code 541380, this is a subcontract opportunity with a response deadline of June 23, 2026, at 7:00 PM. The solicitation was posted on June 17, 2026, providing a six-day window for qualified vendors to submit proposals. While no specific set-aside or point of contact details are provided, the requirement is clearly defined and focused on technical accuracy and certification, emphasizing the need for precise methodology and documented validation. The place of performance and detailed address information are not specified, indicating flexibility in where the testing may be conducted, as long as the analytical standards and deliverables are met.
