NFPA 253: Standard Method of Test for Critical Radiant Flux of Floor Covering Systems Using a Radiant Heat Energy Source, 2011 Edition
|Item # 25311|
For the most accurate measurement of critical radiant flux, use the testing procedures outlined in the 2011 NFPA 253.
Advance knowledge about how materials react to fire is critical to making informed selections. 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: Standard Method of Test for Critical Radiant Flux of Floor Covering Systems Using a Radiant Heat Energy Source 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 or exitway.
Update to the 2011 edition to stay on top of important changes including:
- Added tolerances to dimensions to create harmonization between NFPA 253, ASTM E 648, and ISO 9239-1
- New provisions on laminate specimens
- Revised criteria for specimen size and mounting as well as test reporting requirements
Valuable Annexes discuss how to calibrate an apparatus, mounting methods, sample data logs, proper application and interpretation of results, specific safety precautions, and more. (Softbound, 18 pp., 2011)
