UNSPSC 41113810: Hydrothermal testing equipment

Equipment that experiments how it is changed for rock or mineral of certain kind when the environment is set differently to the conditions of temperature and pressure at the time the rocks or minerals are generated.

UNSPSC 41113810 Hydrothermal testing equipment (Commodity) covers soil compaction and analysis instruments, electrical insulating oil testing services, and geotechnical field and laboratory testing equipment and services that state and local governments procure for transportation, utilities, and construction infrastructure assessment. State and local issuing bodies soliciting under this code include state departments of transportation, city utilities boards, county governments, and municipal public works departments. The work ranges from equipment purchases—such as Proctor soil compactors with integrated soil analyzers—to comprehensive multiyear testing services, including annual sampling and laboratory analysis of power transformer insulating oil, concrete and soil compressive strength testing, asphalt extraction and grading analysis, embankment compaction verification, and in-place soil density testing performed to ASTM and state transportation agency standards. Qualifications typically require licensed Professional Engineers with geotechnical or materials-testing experience, state certifications (such as Georgia Department of Transportation prequalification or state Certificate of Authorization), current nuclear density gauge and American Concrete Institute credentials, and professional liability insurance ranging from $1 million to $2 million.

Recent activity spans Texas, Florida, Georgia, and Michigan.
