| AAMA status | Active | Active | Active |
Comparison
APPA 91, ASTM E119, and NFPA 221 are all standards that define the requirements for fire tests of building materials and assemblies. However, there are some key differences between the three standards.
APPA 91 is the oldest of the three standards, and it is specifically designed for use in the United States. ASTM E119 is a more international standard, and it is often used in conjunction with APPA 91. NFPA 221 is a standard published by the National Fire Protection Association, and it is specifically designed for use in the United States.
In terms of test methods, APPA 91 and ASTM E119 are very similar. Both standards include tests for fire resistance, heat transmission, and smoke development. NFPA 221 includes some additional tests, such as tests for flame spread and smoke density.
In terms of scope, APPA 91, ASTM E119, and NFPA 221 all apply to materials and assemblies used in buildings and structures. However, NFPA 221 also includes some specific requirements for materials and assemblies used in high-rise buildings.
Finally, in terms of publication date, APPA 91 was published in 1991, ASTM E119 was published in 2016, and NFPA 221 was published in 2019.
Which standard should you use?
The best standard to use depends on your specific needs. If you are in the United States and you need a standard that is specifically designed for use in the United States, then APPA 91 is a good option. If you need a more international standard, then ASTM E119 is a good option. If you need a standard that includes specific requirements for materials and assemblies used in high-rise buildings, then NFPA 221 is a good option.
Ultimately, the best way to decide which standard to use is to consult with a fire protection engineer.
