UNSPSC 41114631: Stress tester

Equipment that tests the resistance arising from the object when it is applied with the external force (load) as the stress.

UNSPSC 41114631 Stress tester — a Commodity code — covers laboratory and field testing equipment used by state and local agencies to measure performance, material properties, and system integrity across water utilities, educational institutions, transportation authorities, and specialized laboratories. Recent solicitations reflect a diverse mix of precision measurement and analysis instruments: optical surface profilometers for lens manufacturing education, airfield photometric test systems for runway lighting compliance, high-voltage capacitance measurement modules for utility transformer diagnostics, three-phase meter test boards for electric utility metering programs, atmospheric monitoring sensors for water and wastewater facilities, and specialized analyzers for oil quality, water chemistry, and drug discovery research. Issuing bodies span municipal water and electric utilities (City of Ocala Electric Utility, Kissimmee Utility Authority, City of Tampa Water Quality Laboratory, Lee County Port Authority), public universities (Valencia College, Jackson State University, Texas State University, Texas A&M University System), specialized state health and transportation agencies (Texas Department of State Health Services, Colorado State Patrol), and county governments (Collier County, Marion County). The code encompasses both capital equipment purchases and service agreements for calibration, repairs, maintenance, and technical support; many solicitations combine the instrument itself with required training, installation, commissioning, and ongoing OEM-certified field service.

Geographic activity concentrates in Florida and Texas, with recent opportunities from the City of Tampa, City of Ocala, Kissimmee Utility Authority, Lee County Port Authority, Collier County, Valencia College, Jackson State University (Mississippi), Texas State University, Texas A&M University System, Texas Department of State Health Services, and Colorado State Patrol. Representative solicitations include the City of Ocala Electric Utility's RFP for a fully integrated Three-Phase Meter Test Board system (response deadline April 30, 2026, best-value evaluation weighted toward technical compliance and experience), Lee County Port Authority's e-quote for Airfield Photometric Testing at Southwest Florida International Airport (response deadline October 29, 2026, three-year service contract with FAA compliance and specialized equipment), Kissimmee Utility Authority's IFB for an OMICRON CP TD12 High-Voltage Capacitance Measurement Module (response deadline September 22, 2026, one-time purchase under $250,000), and Jackson State University's sole-source notice for the Schrodinger Small Molecule Drug Discovery Suite software platform (objection period October 13, 2026, $65,318.25 five-year license with academic discounts). Many recent opportunities are sole-source procurements or notes of intent, reflecting the specialized and proprietary nature of precision testing equipment and the OEM certification requirements that often restrict competition.
