FORWORD

NAAMM published the first edition of this manual in 1974. This first edition was entitled "Fire-Rated Custom Metal Doors and Frames". Much progress has been made in the development of door and frame assemblies capable of providing fire protection in wall openings since the publication of the first edition. The second edition was published in 1983.

It is the purpose of this third edition to present data on current practices within the industry with emphasis on the requirements of the National Fire Protection Association (NFPA) and Model Codes within the United States. Fire testing, listing, labeling and certification services are thoroughly covered. The section on hardware and its proper use with fire-rated doors has been considerably expanded. The section on fire-rated products describes classified doors and frames currently available from NAAMM/HMMA member companies. It is believed that this third edition will prove to be a valuable reference manual to those responsible for specifying fire protection products. NAAMM will welcome any comments regarding the content of the manual and will appreciate suggestions for improvement of future editions.
