PSC H928

Overview

The Product Service Code (PSC) system is a four‑character taxonomy used across U.S. federal procurement to classify what was acquired on each contract action reported in FPDS. PSCs enable consistent reporting, spend analysis, category management and contracting accountability; the authoritative descriptions and code assignments are maintained in the FPDS/PSC Manual. ¹

PSC H928 is the PSC assigned to “Other Quality Control, Testing, and Inspection” activities specifically for engines, turbines, and their components. The PSC Manual lists H928 under Category H (Quality Control, Testing, and Inspection) and directs contracting officers to select H928 when the predominant contract line item is non‑standard or “other” QC/testing/inspection for engines, turbines, or components that do not fit a more specific H‑series code. ¹

What this PSC covers

• Non‑routine quality control services for engines and turbines.
• Specialized testing (functional, endurance, performance) of engine components.
• Third‑party inspection and certification of turbine parts not covered by standard inspection codes.
• Laboratory analysis or materials testing related to engine/turbine components.
• On‑site test and evaluation services focused on powerplant or propulsion components.

Common contract uses

• Task orders and firm‑fixed or time‑and‑materials contracts for specialized engine test laboratories performing endurance, vibration, thermal‑cycle, or performance testing that is not captured by a more specific H‑series PSC. ¹
• Single‑award or IDIQ line items where the principal effort is non‑standard QC/test/inspection for engines, turbines or components and does not match more specific inspection or accessory codes. ¹

Reporting & FPDS usage

• FPDS entry guidance requires selecting the PSC that best represents the predominant product or service; agency PGI/DFARS and FPDS instructions describe how to populate FPDS fields and determine the appropriate code. For FPDS entry responsibilities and administrative guidance, see PGI Part 204. ²

Frequently asked questions

• Q: When should a contracting officer select PSC H928 instead of H328?
  A: Use H328 for standard inspection services specifically described for engines/turbines; select H928 when the work is an “other” or non‑standard QC/test/inspection activity that does not align with a more specific H‑series PSC. See the PSC Manual for code definitions. ¹

• Q: Can engine accessory testing be reported under H928?
  A: Engine accessories are normally reported under accessory‑specific PSCs (for example, H929); use H928 only when accessories are not covered by accessory codes or the effort is broadly categorized as “other” QC for engines/turbines. ¹

• Q: Which FPDS field holds the PSC and how is it chosen?
  A: FPDS data element 8A records the PSC value; the selected PSC should represent the predominant product or service procured and be chosen per FPDS and agency guidance. For FPDS/entry responsibilities consult FPDS and PGI guidance. ³

• Q: Which agencies commonly use H928?
  A: Not specified by official sources. ¹
