Fuel cell power systems convert the energy of a fuel and an oxidant directly into electrical energy and heat using an electrochemical process. Fuel cell power systems consist of electrochemical reactors and the balance of plant. Electrochemical reactors convert the energy from chemical to electrical form. Balance-of-plant provides the required reactant and product flows, to […]

1.2.1 This Code provides instructions in Part I for flow capacity testing and in Part II for in-service and bench testing. Testing of reclosing and nonre-closing pressure relief devices is conducted under various inlet and outlet conditions using steam,gases, and liquids for which valid physical properties are known.

This Code applies to all sizes and types of hydraulic turbines or pump-turbines. It defines methods for ascer-taining performance by measuring flow rate (discharge),head, and power, from which efficiency may be deter-mined. Requirements are included for pretest arrange-ments，types of instrumentation， methods of measurement, testing procedures, methods of calcula-tion, and contents of test reports.

The Codes provide test procedures which yield results of the highest level of accuracy consistent with the best engineering knowledge and practice, taking into account the cost of tests and monetary value of efficiency to industry. Performance of equip-ment is determined in part by measurements of physical quantities. A measurement consists of sens-ing a physical
