Which agency's code is referenced in defining appurtenances related to boiler operation?

The American Society of Mechanical Engineers (ASME) is recognized for establishing comprehensive standards and codes that govern the design, construction, and operation of various mechanical systems, including boilers. The appropriate definition of appurtenances, which are additional components or attachments that are essential for the safe operation and functionality of a boiler system, falls under the purview of these ASME standards.

These codes help ensure that all components related to boiler operations meet safety and performance criteria, providing guidelines that help maintain boiler efficiency and safety. Appurtenances can include relief valves, gauges, and other necessary fittings that are integral to the boiler's operation. ASME’s role in defining these parameters is crucial for industry compliance, as it lays down the technical specifications that engineers and operators must adhere to in order to uphold safety standards in boiler operation.

In contrast, while organizations such as the National Fire Protection Association (NFPA) provide crucial safety codes, their focus is not exclusively on the mechanical aspects of boiler and pressure vessel operations like ASME. The International Boiler and Pressure Vessel Code also has guidelines, but it operates in association with ASME frameworks. Meanwhile, the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) primarily concentrates
