UNSPSC 41104503: Ageing ovens

UNSPSC 41104503 Ageing ovens, a Commodity code, captures forced-air and mechanical convection laboratory ovens that state and local transportation and environmental agencies procure for materials testing, asphalt analysis, and quality-control operations. Recent solicitations show state departments of transportation leading activity, purchasing ovens to support pavement and materials testing at district laboratories; the code also appears tagged to an unrelated laboratory testing services contract (City of Palm Bay) and a health information system RFI (Santa Clara County), indicating occasional misclassification in state procurement systems. The actual buying under the code centers on equipment meeting precise technical specifications—forced-air units with stainless steel interiors, digital PID temperature control, tight uniformity and stability tolerances, and single-phase 230-volt power, typically in the 27–28 cubic foot range, shipped to specific district facilities.

Texas Department of Transportation (TxDOT) and Illinois Department of Transportation (IDOT) District 6 dominate recent activity. TxDOT issued three solicitations between May and July 2026—a mechanical convection oven for the Childress District (due July 23, 2026), laboratory ovens and NCAT asphalt furnaces for the Abilene District (due July 13, 2026), and a forced convection oven for horizontal air flow (due May 4, 2026)—all requiring registration on the Euna Procurement platform and the Texas Comptroller of Public Accounts Centralized Master Bidders List. IDOT District 6 rebid a 28 cubic foot forced air unit in June 2026 (due June 25, 2026) and again in May 2026 (due May 8, 2026), with detailed specifications requiring exterior dimensions not exceeding 43×35×86 inches, temperature uniformity within 2.5 degrees Celsius, stability within 0.3 degrees Celsius, UL certification, and delivery to 2420 South Dirksen Parkway, Springfield, Illinois; respondents must carry $1 million per-occurrence and $2 million annual-aggregate general commercial liability coverage and comply with Illinois prevailing wage and equal opportunity requirements. Activity concentrates in Texas and Illinois; vendors must verify current registration and NIGP code classification before submitting bids under either state's procurement platform.
