Which code or standard governs ground source heat pump loop system tests in this context?

• A. NFPA 70
• B. IPC
• C. ASHRAE 90.1
• D. IMC 2000 1208.1.1

Answer: (D)

Ground-source heat pump loop tests fall under the mechanical code that governs how mechanical systems and their piping are installed and verified. The International Mechanical Code (IMC), in the 2000 edition, section 1208.1.1, provides the specific testing requirements for ground-loop (closed-loop) geothermal piping, outlining how these loops should be pressure-tested and inspected to ensure there are no leaks and that the installation is sound before the system operates. Electrical codes (NFPA 70) cover wiring and electrical safety, not the mechanical testing of buried loop piping. The plumbing code (IPC) deals with general plumbing installations but doesn’t typically specify the testing procedures for geothermal loop fields used by heat pumps. ASHRAE 90.1 focuses on energy performance and efficiency requirements, not the testing procedures for loop integrity. Therefore, the IMC provision is the appropriate authority for governing ground loop test requirements in this context.
