This Code Section establishes rules for piping systems within various types of buildings and their property limits. It addresses the design, materials, fabrication, installation, inspection, examination, and testing of these systems, specifically for industrial, institutional, commercial, and public buildings, as well as multi-unit residences. The scope is defined by its exclusion of systems requiring the broader range of sizes, pressures, and temperatures covered by ASME B31.1. This standard provides a framework for ensuring the safe and effective operation of building service piping.

This standard is a technical document intended for professionals involved in the design and construction of building services. Its authority derives from its publication by The American Society of Mechanical Engineers, a recognized body for establishing engineering codes and standards. The document's structured approach to piping systems suggests it is a foundational reference for engineers, contractors, and inspectors working within the specified building types. Its utility lies in providing clear, actionable requirements for ensuring the integrity and safety of building service piping.
