NFPA 253(06)
Standard Method of Test for Critical Radiant Flux for Floor Covering Systems Using a Radiant Heat Energy Source
Approx. 17 pp., 2006
$39.00

Referenced by NFPA 101®: Life Safety Code® and building codes as the test procedure used to determine the critical radiant flux of a material, NFPA 253 is a test method that is designed to provide a basis for estimating one aspect of the fire exposure behavior of a floor covering system installed in a building corridor.

This edition features clarified requirements and compliance with NFPA's Manual of Style. Chapters cover:

  • Safety Precautions
  • Radiant Heat Energy Flux Profile Standardization
  • Test Procedure
  • Calculations

Additional detail was provided on simulating a concrete floor during the test. Provisions regarding safety precautions were moved to the Annex material, which also includes a procedure for calibration of apparatus, mounting methods, a sample data log, and commentary on critical radiant flux test.
