The Department of Defense, specifically the U.S. Army Contracting Command at Redstone Arsenal, is seeking accredited calibration and repair services for fifteen specialized test unit items, including various attenuator sets and resistors. This procurement action is a follow-on requirement based on previous calibration conducted by APSL, which identified the necessity for specific brand calibration due to unique mission requirements and increased costs from NIST. The contract may include both cost reimbursable and fixed-price elements, with the equipment being shipped overseas for servicing, emphasizing the importance of brand-specific calibration for the Army's operational needs.
