UNSPSC 41114627: Proving ring

A standard device used for the calibration test of tension and compression load of all-purpose material tester. It is designed to use for load inspection and ordinary management of the material tester.

UNSPSC 41114627 Proving ring is a Commodity code that spans laboratory and field testing equipment used across state and local public bodies to measure force, load capacity, and material properties. Recent state and local opportunities under this code show a divergence from the abstract commodity name: the actual procurements reflect a much broader range of precision testing and measurement systems, including optical surface profilers, spectrophotometers, brake testers, high-voltage capacitance modules, meter test boards, and laboratory sterilization and oil analysis equipment. State and local issuing bodies range across higher-education institutions (Valencia College, Jackson State University, Texas State University, Texas A&M University System), municipal utilities (City of Ocala Electric Utility, Lee County Port Authority, Lubbock Power & Light, Kissimmee Utility Authority, City of Tampa), county and state agencies (Colorado State Patrol, Marion County, Texas DSHS, Collier County), and regional authorities. Jackson State University, Lee County Port Authority, and the City of Tampa appear in multiple recent solicitations. Higher-education institutions drive significant activity through their research and instructional laboratory needs, while municipal utilities concentrate on equipment for water quality, electrical metering, and airfield operations testing.

Geographic spread across recent opportunities spans Florida (Valencia College, Lee County Port Authority, City of Ocala, City of Tampa, Collier County), Texas (Jackson State University, Texas State University, Texas A&M University System, Texas DSHS, Lubbock Power & Light), Colorado (Colorado State Patrol), Oregon (Marion County), and Arizona (City of Phoenix). Representative recent opportunities include Lee County Port Authority's request for quotations on airfield photometric testing at Southwest Florida International Airport (RFQ 2026115BW, due October 29, 2026), Kissimmee Utility Authority's IFB for a precision high-voltage capacitance measurement module (IFB 26046JG, due September 22, 2026), City of Ocala Electric Utility's RFP for a Three-Phase Meter Test Board system (RFP ELE/260570, due April 30, 2026), and Texas DSHS's IFB for laboratory equipment repair and maintenance services covering Lancer and Getinge sterilization systems (HHS0017421V2, due August 26, 2026). Many procurements under this code are sole-source awards or notices of intent to single-source, reflecting vendor lock-in around proprietary equipment integrations and specialized calibration requirements inherent to precision testing.
