UNSPSC 41114602: Compression testers

UNSPSC 41114602 Compression testers is a Commodity code that encompasses specialized equipment for laboratory and field testing of materials—primarily concrete, plastic pipe, and load cells—used by state and local transportation departments, utilities, and water authorities. State and local governments purchase compression testing machines, load cell calibration services, and related materials-testing equipment under this code to support quality assurance and compliance verification during construction and infrastructure maintenance projects.

The issuing bodies are predominantly state departments of transportation (Georgia DOT, Illinois DOT) and municipal utilities (Kissimmee Utility Authority, Wayne County Water Resource Recovery Facility, City of Fort Myers). Illinois DOT appears as a repeat buyer, posting multiple rebid solicitations for large-bed and small-bed compression machines, as well as load cell calibration services. Georgia DOT has posted several construction engineering and inspection opportunities that incorporate materials testing requirements. Geographic activity concentrates in Illinois, Georgia, Florida, and Michigan, with recent opportunities spanning late May through mid-October 2026. Representative solicitations include the Illinois Department of Transportation's rebid for a Large Bed Compression Machine (IFB 27494DOTFINADB53631, due September 9, 2026) seeking a newly manufactured unit capable of testing plastic pipe per AASHTO and ASTM standards with specified load capacity and crosshead speed; the Illinois Department of Transportation's rebid for ASTM E74 load cell calibrations (IFB 27494DOTFINADB53622, due September 15, 2026) requiring ISO/IEC 17025 accreditation and NIST traceability; and the City of Fort Myers' ongoing material testing services contract (RSQ 25054, due May 23, 2025) seeking Florida-registered Professional Engineers to provide field investigations, laboratory testing, concrete and bituminous services, and materials inspections on an as-needed basis. The Kissimmee Utility Authority procured a single precision high-voltage test module (IFB 26046JG, due September 22, 2026) compatible with existing OMICRON systems. State contracting vehicles favor fixed-price purchases for equipment and ISO/IEC 17025 certified calibration services structured as multi-year contracts with renewal options; professional liability and commercial general liability insurance are standard requirements.
