Before diving into the Piping Handbook, it is crucial to understand the authority behind it. The International Institute of Ammonia Refrigeration (IIAR) is a non-profit trade association dedicated to the safe use of ammonia as a refrigerant. Their standards (e.g., IIAR 2, IIAR 3, IIAR 4, and IIAR 5) are recognized globally by OSHA (Occupational Safety and Health Administration) and building codes as the benchmark for safe system design.
The IIAR Ammonia Refrigeration Piping Handbook is a companion document to these standards, specifically expanding on piping design requirements found in IIAR 2 (American National Standard for Safe Design of Closed-Circuit Ammonia Refrigeration Systems).
Engineers, designers, piping/fabrication contractors, safety professionals, plant operators, and maintenance personnel involved with ammonia refrigeration systems.
If you work in ammonia refrigeration daily, consider an IIAR Digital Library subscription. For a flat annual fee (often $500–$1,000), you get access to all IIAR standards, bulletins, and handbooks, including the piping handbook, in a searchable PDF interface.
Follow the IIAR handbook as the ammonia-specific complement to mandatory codes (ASME, ANSI, NFPA). Use it to develop project specifications, P&IDs, inspection routines, and safe commissioning procedures. Where local codes conflict, comply with the more stringent requirement and document the rationale.

The Quest for Knowledge
John had been working as a refrigeration engineer for several years, but he had recently taken on a new project that required him to design an ammonia refrigeration system. He knew that ammonia was a highly toxic and flammable substance, and he needed to ensure that his design was safe and compliant with industry standards.
As he began to research the requirements for ammonia refrigeration systems, John realized that he needed to get his hands on a copy of the IIAR Ammonia Refrigeration Piping Handbook. The handbook was published by the International Institute of Ammonia Refrigeration (IIAR) and was widely regarded as the industry standard for designing and installing ammonia refrigeration systems.
John searched online for a PDF link to the handbook, but he couldn't seem to find one. He tried visiting the IIAR website, but the handbook was only available for purchase in print or digital format. John was hesitant to spend the money, especially since he only needed to access the handbook for a short period.
The Solution
Just when John was about to give up, he stumbled upon a post on a refrigeration engineering forum. One of the users had shared a link to a PDF version of the IIAR Ammonia Refrigeration Piping Handbook. John was skeptical at first, but he decided to give it a try.
He clicked on the link and was able to access the PDF handbook. He was relieved to find that it contained all the information he needed to design a safe and compliant ammonia refrigeration system.
The Takeaway
John was grateful to have found the PDF handbook, and he realized that sometimes, it pays to be persistent and look for alternative sources of information. He also learned the importance of verifying the credibility of sources, especially when working with hazardous substances like ammonia.
