PSC H947

Overview

The Product Service Code (PSC) system is the standardized federal taxonomy used to classify services and products for U.S. government procurement, enabling consistent reporting in FPDS, SAM, and other acquisition systems. The PSC Manual on Acquisition.gov is the authoritative maintenance instrument for PSC assignments, revisions, and guidance for contract data reporting and selection. The PSC entry H947 identifies inspection, testing, verification, and quality-assurance services specifically applied to pipe, tubing, hose, and fittings—covering on-site or shop inspections, non‑destructive testing, laboratory sampling, dimensional and materials checks, and certification activities that support acceptance and contract reporting for these fluid- and conduit-related hardware categories.¹

What this PSC covers

• Quality-control inspection services for pipe and tubing.
• Non‑destructive testing and test reports for hoses.
• Dimensional and materials verification for fittings.
• Laboratory testing and sampling associated with piping components.
• On-site or shop inspection of assembled conduit systems.
• Documentation, acceptance testing, and certification services for installed piping assemblies.²

Contracting considerations

• Statement of work clarity: Performance work statements should define inspection standards, test methods, acceptable tolerances, and required certifications to align contract reporting under PSC H947. Not specified by official sources¹.
• Pricing approach: Typical procurements use time-and-materials, firm-fixed-price, or unit-rate line items based on inspection scope and laboratory needs; specific federal pricing guidance for PSC H947 is not specified by official sources¹.

Typical government uses

• Pre-delivery inspection of contractor-fabricated piping spools prior to installation in facilities or ships (quality assurance and acceptance). Not specified by official sources².
• Surveillance testing and periodic re-certification of hoses and fittings used in mission-critical systems. Not specified by official sources².

Frequently asked questions

• What is the official authority for PSC definitions and updates?

  • The PSC Manual on Acquisition.gov is the official source that defines and maintains PSC entries and guidance used by contracting officers and data reporters; it explains maintenance procedures and how PSCs must be applied for reporting. ¹

• Is H947 a supply or service code for catalog purchases?

  • PSC H947 is a service-class PSC used to report and classify inspection, quality-control, and testing services associated with pipe, tubing, hose, and fittings rather than commodity-only purchases. ²

• How should a contracting officer choose H947 versus another inspection PSC?

  • Selection depends on the procurement’s primary subject. Use PSC H947 when the primary service targets pipe, tubing, hose, or fittings; otherwise select the PSC that matches the primary inspected item per the PSC Manual. ¹

• Are standard test methods (e.g., ASTM, ASME) prescribed by the PSC entry?

  • The PSC entry describes the classification purpose only; specific standards or test methods are not prescribed by the PSC entry and must be specified in contract quality requirements. Not specified by official sources¹

• Can H947 be used for recurring maintenance inspections?

  • PSC H947 may be reported for recurring inspection and testing services when the service’s primary scope matches pipe, tubing, hose, and fittings; contracting documentation should state frequency and acceptance criteria. Not specified by official sources¹
