PSC H228

Overview

The Product Service Code (PSC) is the U.S. federal government’s standardized classification system for labeling goods and services in procurement records. PSCs enable consistent reporting, budgeting, trend analysis, and contract management across agencies and appear in systems such as FPDS and SAM; the PSC Manual is the authoritative source for structure and usage. ¹

PSC H228 — Equipment and Materials Testing- Engines, Turbines, and Components — identifies testing, inspection, and laboratory services focused on engines, gas and steam turbines, and their constituent parts. The published PSC entry provides the high-level scope used for FPDS reporting and contract classification; specific tasks, deliverables, and standards are defined at the solicitation or order level. ²

What this PSC covers

• Engine and turbine performance testing, calibration, instrumentation verification, and diagnostic services to evaluate power, efficiency, emissions, and reliability. ²
• Component-level materials and failure analysis for blades, shafts, seals, bearings, and seals, including metallurgical, fracture, and wear examinations. ²
• Vibration, thermal, acoustic, and rotor-dynamics testing for rotating machinery, including modal analysis and balance/coupling assessments. ²
• Propulsion-system endurance, lifecycle, and acceptance testing, including bench, cell, and full-system runs under specified operational profiles. ²
• Test-stand design support, sensor and data-acquisition integration, and generation of characterization and compliance reports used for certification or fielding decisions. ²

Typical procurement notes

Contract line items under PSC H228 commonly describe discrete test services, characterization reports, acceptance testing, or certification runs required prior to equipment fielding; agencies specify technical performance parameters, deliverable formats, schedules, and data deliverables within solicitations or task orders. Not specified by official sources. ¹

Technical compliance considerations

Test laboratories and service providers performing work under PSC H228 frequently follow recognized industry and laboratory standards and best practices for engine and turbine testing, but the PSC Manual itself does not prescribe particular technical standards or accreditations; agencies set required standards, test methods, and any necessary certifications in the solicitation. Not specified by official sources. ¹

Frequently asked questions

• Q: What kind of solicitations use PSC H228?
  A: Solicitations that procure laboratory testing, inspections, acceptance tests, or characterization services focused on engines, turbines, and related components will record PSC H228 in FPDS reporting; the solicitation will provide the detailed scope, CLIN structure, and applicable standards. ²

• Q: Does PSC H228 require specific laboratory accreditation?
  A: The PSC Manual does not mandate accreditations for H228; procuring agencies typically require specific accreditations or qualifications (for example, ISO/IEC 17025) in the statement of work or evaluation criteria when appropriate. Not specified by official sources. ¹

• Q: How is H228 used in federal spending reports?
  A: Agencies record PSC H228 on contract actions and award summaries in FPDS to categorize expenditures for engine- and turbine-related testing; this enables analysts to track spending by product/service category and supports interoperability of procurement data across systems. ¹

• Q: Are component repairs or overhaul services covered under H228?
  A: PSC H228 is specific to equipment and materials testing for engines, turbines, and components; maintenance, repair, overhaul, and rebuild services are normally classified under separate PSCs and should be confirmed against the PSC Manual or agency guidance. Not specified by official sources. ¹
