IIAR 4 Certificate Program    

It is anticipated that course participants will become familiar with the ANSI/IIAR 4-2020 Standard for Minimum System Safety Requirements for the Installation of Closed-Circuit Ammonia Refrigeration Systems and be able to apply those requirements to a safely installed and operated refrigeration system. 

This course is intended to serve as continuing education for industrial refrigeration professionals whose job responsibilities include installation and safe operation of closed-circuit ammonia refrigeration systems. This audience would include plant managers, maintenance directors and supervisors, designers, engineering managers, facilities engineers, facility managers, service technicians, mechanical engineers, and refrigeration engineers, as well as employees who focus on regulatory requirements for ammonia refrigeration systems.

Syllabus for IIAR 4 Certificate Course 

Module 1 
Background, References, and General Requirements for Installation 

This module reviews the first half of the IIAR 4 standard. Content includes an examination of the standard's purpose, scope and applicability to safe installation of closed-circuit ammonia refrigeration systems, along with key definitions of terminology used in the standard. We’ll also address requirements for supervision of an installation, installer qualifications, contractor responsibilities, and safety training. IIAR 4 includes requirements for welding, suitable materials that can be used in the presence of ammonia, and allowable locations for components. The module wraps up with some non-mandatory recommendations for useful documentation that should be collected during the installation process. 

Module 2 
Installation of Piping/Controls/Insulation; Leak/Pressure Testing 

The second module in the IIAR 4 certificate course looks at the second half of the IIAR 4 standard, including requirements for equipment installation and for installation of pipe, valves, and flanges.  Module 2 also reviews installation of visual indicators and dives into both normative and informative specifications for installation of ammonia system insulation.  We wind up with a list of recommended references that would be useful to consult before undertaking an ammonia refrigeration installation project.  


Learning Objectives
After completing this program, learners will be able to:

  • Explain the difference between normative and informative content in the IIAR 4 standard. 
  • Discuss general requirements for installation of an ammonia refrigeration system. 
  • List helpful installation documentation to request during procurement. 
  • Discuss general requirements for installation of an ammonia refrigeration system 
  • Discuss piping installation  
  • Discuss components and controls installation  
  • Identify considerations regarding insulation systems for ammonia refrigeration 

Continuing Education Credits 
After completing an IIAR Academy of Natural Refrigeration certificate course, successfully completing the accompanying quizzes, and passing the final course exam, you will earn the corresponding number of continuing education credits, which can be applied toward maintaining P.E. licensure. IIAR is accredited by the Registered Continuing Education Program for Engineers, Surveyors & A/E/C Professionals (RCEP) as an approved provider of continuing education  

The IIAR 4 certificate course offers 2.0 Professional Development Hours (PDHs) for learners who successfully complete the course. 

The IIAR Academy of Natural Refrigerants is a long-term education program created to address the need for competent professionals in natural refrigeration system design, safety, and maintenance. The objective of the academy is to address the technical training needs of end users, design build contractors, equipment manufacturers, operators, safety/PSM specialists, and consulting engineering sectors of the IIAR membership. As industry codes and regulations change and evolve the need for competent professionals in our industry will continue to grow.  

IIAR Certificate Courses are based on ASTM standards and allow industrial refrigeration professionals to show that they have received documented and standardized instruction regarding the requirements for safe design and operation of ammonia-based refrigeration systems.

How It Works
The IIAR 4 Certificate course includes two training sessions, each approximately 60 minutes long, delivered as a PowerPoint presentation with lecture. At the end of each module, you must successfully complete a short quiz to check your comprehension of the material. To receive a certificate and continuing education credit, participants will be required to pass all quizzes as well as a final course examination, which is included in the course registration fee. 

Final Exam 
The final course examination will be administered online. Qualified registrants MUST have paid their Certificate Course tuition and MUST have successfully completed the Module 1 and 2 Quick Check Quizzes (at least 80% correct on both quizzes).
