PSC H252

Overview

The Product Service Code (PSC) framework is the federal government’s standardized taxonomy for classifying purchased products and services reported in procurement systems such as FPDS and SAM; the PSC Manual on Acquisition.gov documents the codes, usage rules, and management processes that govern those classifications. PSC H252 is the service-category entry within the Equipment-Related Services family for “Equipment and Materials Testing — Measuring Tools.” The PSC Manual lists H252 under the Equipment and Materials Testing group (Group 52), indicating the code is intended to record testing, calibration, and related quality-control services associated with craftsmen’s and precision measuring tools on contract actions reported in FPDS. ¹

What this PSC covers

• Testing and calibration services for craftsmen’s measuring tools (calipers, micrometers, levels). ¹
• Inspection and verification of inspection gages and precision layout tools. ¹
• Acceptance and functional testing of measuring-tool sets, kits, and outfits. ¹
• Generation of test reports, certificates of calibration, and measurement traceability documentation — not specified in detail by the PSC Manual. ¹
• On-site or laboratory-based evaluation of measuring-tool performance against standards — not specified in detail by the PSC Manual. ¹

Product examples (official product-class linkage)

• Craftsmen’s measuring tools: calipers, micrometers, levels, squares, height gages (PSC product class 5210). ¹
• Inspection gages and precision layout tools: Go/No-Go gages, profile and fixture gages (PSC product class 5220). ¹

Frequently asked questions

• Q: What specific services should be coded to PSC H252?
  A: Services that are predominately testing, calibration, or quality-evaluation of measuring tools should be coded to PSC H252 when that testing/calibration is the primary service on the procurement action. See the PSC Manual for the official listing. ¹

• Q: How does H252 differ from inspection codes such as H352?
  A: PSC H252 is a testing-category service code for measuring tools; PSC H352 is an inspection-oriented code. Agencies select the code that best matches the work scope (testing/calibration vs. inspection/verification). ¹

• Q: Are specific measuring-tool models or calibration standards mandated by the PSC Manual?
  A: The PSC Manual enumerates product classes and examples (for instance, product class 5210 lists calipers and micrometers) but does not mandate specific models or calibration standards; technical specifications and standards are handled in the contract statement of work and technical attachments. ¹

• Q: Where should a contracting officer look to validate PSC selection for a measuring-tool procurement?
  A: Use the PSC Manual’s Group 52 entries for authoritative product-class descriptions and the FPDS ezSearch/help pages for coding and reporting guidance; FPDS is the primary reporting tool for PSC selections. ²
