NFPA 220 STANDARD ON TYPES OF BUILDING CONSTRUCTION
NFPA 220 建筑物分类标准

1.1* Scope. This standard defines types of building construction based on the combustibility and the fire resistance rating of a building’s structural elements. Fire walls, nonbearing exterior walls, nonbearing interior partitions, fire barrier walls, shaft enclosures, and openings in walls, partitions, floors, and roofs are not related to the types of building construction and are regulated by other standards and codes, where appropriate.
Build in fire safety from the start by making informed construction classifications based on the 2012 NFPA 220.
NFPA 220 Standard on Types of Building Construction defines construction assemblies based on the combustibility and the fire resistance rating of their structural elements. It is an extract document of Section 7.2 NFPA 5000? Building Construction and Safety Code -- the only ANSI-approved building code that spans new construction and building rehabilitation.
Revised to reflect current construction descriptions and technologies, the 2012 NFPA 220 includes new extracted language from NFPA 90A Standard for Installation of Air Conditioning and Ventilating Systems on ceiling cavity plenums and new definitions of 'limited-combustible material' and 'non-combustible material'.
Architects, engineers, authorities having jurisdiction (AHJs), and anyone responsible for making construction classifications needs the 2012 edition to maximize fire protection and safeguard lives and property. (Softbound, 12 pp., 2012)
