PSC L052

Overview

The Product Service Code (PSC) is the federal government's standardized classification scheme for products and services used in procurement reporting and analysis. PSCs enable consistent tagging of contract actions in systems such as FPDS and SAM, support spend analytics, and are maintained and published through the official PSC Manual on Acquisition.gov.¹

The PSC entry L052 is listed in the PSC Manual as "Technical Representative- Measuring Tools" under Category L. The official manual provides the code title and category placement but does not enumerate a detailed activity list or an exhaustive scope of work for L052; agencies interpret and apply the code to procure technical‑representative services associated with measuring tools as appropriate to the requirement.²

What this PSC covers

• Technical representative services for measuring tools (title‑derived)
• On‑site product demonstration and user training
• Field liaison for warranty, service, and vendor coordination
• Calibration coordination and verification support
• Field troubleshooting and equipment configuration assistance
• Documentation of service actions and technical reporting

Note: The PSC Manual supplies the code name and Category L placement but does not define a prescriptive list of activities specific to L052; detailed inclusions and exclusions are determined by the procuring agency in the solicitation or contract statement of work.²

When agencies typically assign L052

Assign L052 when the procurement's primary deliverable is vendor or manufacturer technical liaison, on‑site support, or similar services tied to measuring tools rather than the acquisition of measuring‑tool hardware as an end item. Agencies choose the PSC that best represents the predominant product or service for FPDS reporting and follow FPDS/PGI reporting guidance when making that assignment.³

Contracting considerations

Solicitations and contracts must state the technical‑representative tasks, deliverables, and performance standards since the PSC itself does not prescribe those details. Agencies should pair L052 with an appropriate principal NAICS code in solicitations per FAR reporting requirements; contracting officers must document and justify the principal NAICS selection in the solicitation/award per FAR guidance.⁴
