It sounds like you have come across a very valuable resource. If you work with industrial refrigeration, the is considered the "bible" for ammonia piping design and installation.
Unlike generic piping standards, this handbook is specific to the unique thermodynamic properties of Anhydnia (R-717). Ammonia behaves differently than standard fluids or other refrigerants (like HFCs), and the IIAR (International Institute of Ammonia Refrigeration) addresses these nuances specifically.

: Most industrial systems use carbon steel, while stainless steel is often preferred for evaporator coils and internal piping. IIAR Pipe Marking Standards It sounds like you have come across a very valuable resource
The is a comprehensive technical guide published by the International Institute of All-Natural Refrigeration (IIAR). While many search for a "PDF" version, it is formally part of the IIAR’s educational and design series, complementing IIAR Standard 2 (the design, construction, and operation of ammonia refrigeration systems). Ammonia behaves differently than standard fluids or other
The handbook covers critical engineering and safety protocols, including:
