ASTM E736
Full Name
ASTM E736 – Standard Test Method for Cohesion/Adhesion of Sprayed Fire-Resistive Materials Applied to Structural Members
Scope
ASTM E736 outlines a procedure for evaluating the bond strength of sprayed fire-resistive materials (SFRMs) applied to structural elements. This test method is crucial for ensuring the reliability and performance of fire protection systems in buildings and infrastructure.
The test involves applying a specific force to a standardized area of the SFRM using a pull-off adhesion tester. The force is gradually increased until failure occurs. Failure can manifest as either adhesive failure (between the SFRM and the substrate) or cohesive failure (within the SFRM itself).
Key information provided:
- Adhesion/cohesion strength: the test quantifies the force required to separate the SFRM from the substrate, providing a direct measure of the bond strength.
- Failure mode: understanding whether failure occurs within the SFRM or at the interface with the substrate is essential for identifying potential weaknesses and optimizing application techniques.
ASTM E736 is relevant to a wide range of stakeholders including:
- SFRM manufacturers: demonstrating product performance and meeting industry standards.
- Building owners: verifying the effectiveness of fire protection systems in their structures.
- Regulatory bodies: establishing performance benchmarks for fire safety codes.
