What Is the ICC F29-N Examination?

The F29-N examination is the ICC National Standard Master Mechanical examination. Participating jurisdictions may use it as part of a master mechanical contractor, HVAC contractor, qualifying-party, supervisor, or similar licensing process.

The current examination information lists:

• 100 multiple-choice questions
• Four-hour testing limit
• Open-book format

Most ICC Contractor and Trades examinations require at least 70 percent correct, but candidates should confirm the exact F29-N passing requirement before testing.

Passing the examination does not automatically issue a mechanical contractor license. The applicable licensing authority controls experience, insurance, applications, fees, business requirements, and final approval.

F29-N Exam References

The current F29-N package identifies two primary references:

• International Mechanical Code, 2015 Edition
• International Fuel Gas Code, 2015 Edition

The International Mechanical Code supports preparation involving appliances, equipment, ventilation, exhaust systems, ducts, combustion air, chimneys, boilers, hydronic systems, refrigeration, and special mechanical installations.

The International Fuel Gas Code supports preparation involving fuel-gas piping, pipe sizing, valves, regulators, appliance connections, pressure testing, combustion air, chimneys, vents, and fuel-gas safety.

Candidates should confirm that these editions match their scheduled examination before purchasing materials or registering.

How the Two References Work Together

• Use the International Mechanical Code for HVAC equipment, ventilation, exhaust, duct systems, refrigeration, boilers, hydronics, and general mechanical installations.
• Use the International Fuel Gas Code for gas supply piping, regulators, shutoff valves, appliance fuel connections, pressure testing, combustion air, chimneys, and vents.

Some questions may involve both references. A gas-fired furnace, for example, can involve equipment clearances and installation requirements from the mechanical code together with gas supply and venting requirements from the fuel-gas code.

Confirm Local Licensing Requirements

Before purchasing materials or scheduling the F29-N examination, candidates should verify:

• Whether the licensing authority accepts F29-N
• The scope of the master mechanical classification
• The required code editions
• The approved reference list
• The current question count and time limit
• The required passing score
• Rules for tabs, highlighting, and notes
• Required mechanical or HVAC experience
• Insurance and bonding requirements
• Application and examination fees
• Business or qualifying-party requirements
• Renewal and continuing-education requirements
