Open Book Test

The Arizona CR-39 Air Conditioning and Refrigeration examination is an open-book test using approved reference materials. Candidates are responsible for bringing permitted books and following the current testing-provider rules for editions, highlighting, annotations, indexing, permanent tabs, attachments, and book inspection.

An open-book format does not eliminate the need for technical preparation. Candidates must recognize the subject of each question, select the appropriate reference, locate the applicable provision, interpret the information, and apply it to the HVAC or refrigeration condition presented.

All books are highlighted and Tabbed. Highlighting draws attention to useful safety requirements, fuel-gas provisions, mechanical-code rules, equipment information, refrigeration concepts, boiler systems, duct design, formulas, tables, and field procedures. Permanent tabs help candidates move among major sections efficiently.

The references should be used throughout the course rather than opened for the first time on exam day. Repeated navigation practice helps candidates become familiar with indexes, definitions, tables, diagrams, code sections, technical illustrations, and permanent tab locations.

A question involving fuel-gas piping, appliance connections, shutoff valves, combustion air, pressure testing, or venting may require the International Fuel Gas Code. Questions involving air conditioning, refrigeration, heating, ventilation, ducts, boilers, and hydronic systems may require the International Mechanical Code.

Questions involving construction-site safety, ladders, fall hazards, electrical exposure, tools, material handling, or protective equipment may require OSHA 29 CFR Part 1926.

Modern Refrigeration and Air Conditioning supports broader technical preparation involving equipment, refrigerants, electrical principles, controls, service, and troubleshooting. Low Pressure Boilers supports boiler-system review, while Manual D and the Ductulator support airflow and duct-design preparation.
