Standard for Safety Rapid Rise Fire Tests of Protection Materials for Structural Steel - Fourth Edition
N 1709
Annotation
These requirements describe a test method measuring the resistance of protective materials to rapid-temperature-rise fires.
The test method covers a full-scale fire exposure, intended to evaluate the thermal resistance of protective material applied to structural members and the ability of the protective material to withstand the fire exposure.
The test method also covers a small-scale fire exposure, intended to evaluate the ability of protective materials to withstand a variety of environmental conditions anticipated.
