UNSPSC 12142208: Calibration sources

UNSPSC 12142208 Calibration sources (Commodity) covers EPA Protocol calibration and audit gases — certified gas mixtures in cylinders prepared to federal emissions standards and traceable to National Institute of Standards and Technology reference materials. State and local governments buy these gases primarily to support continuous emissions monitoring systems at municipal facilities subject to air quality regulation, particularly cogeneration plants and industrial equipment requiring compliance certification. The work involves supply and delivery of mixtures conforming to EPA G1 methods, typically priced per 144-cubic-foot cylinder with initial setup including redundant in-use and standby inventory and ongoing fast-turnaround replenishment. Issuing bodies include county public works departments and municipal utilities managing emissions compliance infrastructure.

The contract is available as a cooperative purchasing vehicle to other municipalities, public utilities, educational institutions, and nonprofits upon execution of subordinate agreements. A 5% local small business and disabled veteran business enterprise bid preference applies with a maximum deduction of $100,000. Performance and labor and material payment bonds are required, and bids are valid for 365 days following the closing date.
