Spray Applied Fireproofing Special Inspector By Testing Service Corporation

What is involved in a Fireproofing Material Inspection?

TSC inspects Spray-Applied Fireproofing for thickness, density, and cohesion. We follow the Standard American Society of Testing Materials (ASTM) designations E605-93 and E736-00.

Thickness is determined by the shape and thickness of the steel. A fire rating is issued by the designers, individual thicknesses are determined for each column, beam, deck and/or joists. Our personnel measure the thicknesses to ensure that it falls within the construction design specifications.

Density will be determined in the lab and computed by the engineering staff after collecting samples onsite. Samples will be dried and weighed.

Cohesion will be determined in the field with a scale. Using an adhesive, our technician will glue a cap to the fireproofing material. After the glue has set up, the scale will be attached to the cap and gently pulled on until the scale is maxed out, or until failure occurs.

However, if failure occurs between the steel member and the fireproofing, further investigation will be needed to determine if the cohesion value is acceptable.
