UNSPSC 41111620: Etalon wedge

UNSPSC 41111620 Etalon wedge is a Commodity code, but the recent state and local opportunities tagged under it do not reflect procurement of optical or measurement wedges. Instead, the code shows activity driven by laboratory and analytical equipment solicitations that have been miscoded or tagged with a broad taxonomy entry. The City of Fort Worth Purchasing Division's RFQt for a programmable TKN/TPO4 Digestion Block System for water quality analysis (posted March 19, 2026, due March 25, 2026) and the County of Santa Clara's RFI for a lab information management system (LIMS) replacement (posted April 7, 2026, due April 22, 2026) represent the recent tagged opportunities, but neither involves etalon wedges or optical instrumentation in their actual scope. State and local governments are using this code primarily to solicit water quality testing equipment and laboratory information systems from city water departments and county public health agencies.

Activity under this code is concentrated in California and Texas, with the City of Fort Worth and County of Santa Clara appearing in recent months. The Fort Worth digestion block solicitation specifies technical requirements including EPA Method 351.2 and 365.4 compliance, 380-degree temperature capability, digital controller with method storage, and comprehensive insurance and warranty terms, with award to the lowest responsive and responsible bidder. The County of Santa Clara's LIMS RFI seeks vendors capable of delivering scalable, compliant lab information systems supporting complete public health lab workflows, though no budget, incumbent vendor information, or specific evaluation criteria are disclosed in the available materials. The code shows limited recent relevant activity; vendors evaluating this code should note the mismatch between the nominal commodity scope (optical wedges) and the actual laboratory equipment procurement now appearing under it.
