UNSPSC 41104503: Ageing ovens

UNSPSC 41104503 Ageing ovens (Commodity) covers laboratory and testing ovens and furnaces that state and local transportation and materials departments procure for asphalt, concrete, and materials characterization work. Recent opportunities reveal state departments of transportation soliciting forced-air convection ovens, NCAT asphalt content furnaces meeting ASTM and AASHTO burn-off test standards, and specialized lab ovens with digital temperature control and stainless steel interiors. The Texas Department of Transportation (TxDOT) and Illinois Department of Transportation (IDOT) District 6 are the primary repeat buyers under this code. TxDOT applies Texas procurement preferences including Texas-produced supplies, USA-produced equipment, service-disabled veteran-owned business priority, and energy-efficiency considerations; both agencies enforce registration requirements on their centralized bidder lists (Texas Comptroller CMBL, Illinois standard vendor systems) and require compliance with prevailing wage and equal opportunity certifications where applicable. Most recent solicitations specify delivery to district lab facilities and acceptance testing windows (15 to 45 calendar days failure-free operation for asphalt furnaces).

Texas and Illinois dominate recent activity. TxDOT's Abilene District posted three related opportunities between June and July 2026: IFB 601340000066830 (due August 6, 2026) for two 10.6-cubic-foot digital ovens and three NCAT asphalt furnaces with Gilson equipment specifications or TxDOT-approved equals; IFB 601340000066278 (due July 13, 2026) for similar laboratory ovens and NCAT furnaces; and a mechanical convection oven from the Childress District (due July 23, 2026) with limited scope detail available. IDOT District 6 issued two rebids for 28-cubic-foot forced-air lab ovens with identical specifications: solicitation 26494DOTFINADB52235 (due May 8, 2026) and a reissued 27494DOTFINADB52856 (due June 25, 2026), each requiring single-phase 230V 60Hz power, stainless steel interior, temperature uniformity within 2.5 degrees Celsius, digital PID control, and UL listing or national lab certification. TxDOT also solicited a horizontal air flow cabinet oven (IFB 601310000101248, due May 4, 2026). All opportunities require submission through state procurement portals and vendor registration compliance; most specify 12-month warranties and comprehensive documentation including parts lists and authorized service-dealer networks.
