Chapter 13 Sprayed Fire Resistant Materials
Spray-Applied Fire Resistant Material (Council of American Structural Engineer’s Guide)
1. Material Specifications
2. Laboratory Tested Fire Resistance Design
Review UL fire resistive design for each rated beam, column, or assembly.
3. Schedule of Thickness
Review approved thickness schedule.
4. Surface Preparation
Inspect surface preparation of steel prior to application of fireproofing
Inspect application of fireproofing.
6. Curing and Ambient Condition
Verify ambient air temperature and ventilation is suitable for application and curing of fireproofing.
Test thickness of fireproofing (ASTM E605). Perform a set of thickness measurements for every 1,000 SF of floor and roof assemblies and on not less than 25% of rated beams and columns.
Test the density of fireproofing material (ASTM E605).
9. Bond Strength
Test the cohesive/adhesive bond strength of fireproofing ASTM E736). Perform not less than one test for each 10,000 SF.
