Standard Test Method for Effect of Impact on Bonding of Sprayed Fire-Resistive Material Applied to Structural Members
SIGNIFICANCE AND USE
4.1 The intent of this test method is to determine a property of SFRM that may be used to provide an indication of its in-place serviceability. Satisfactory performance of SFRM applied to structural members and assemblies depends upon its ability to withstand the various influences that may occur during construction and during the life of the structure, as well as upon its satisfactory performance under fire conditions.
4.2 The test method measures the behavior of SFRM when the floor construction to which it is applied is subjected to shock loading and evaluates adhesion and resistance to spalling, cracking, and delamination. It is an indication of the ability of SFRM to remain in place and resist removal during anticipated service conditions.
SCOPE
1.1 This test method covers a procedure for determining the effect of impact loading on the bonding of sprayed fire-resistive material (SFRM) applied to the underside of steel floor deck. These materials include sprayed fibrous and cementitious materials applied directly in contact with the structural members. The test method is applicable only to laboratory procedures.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview
ASTM E760/E760M-92(2023) sets forth a standardized laboratory procedure to determine the effect of impact loading on the bonding characteristics of sprayed fire-resistive material (SFRM) applied to the underside of steel floor decks. By assessing the ability of SFRM to withstand shock impacts, this test method offers valuable insights into the material’s in-place serviceability-a critical factor in maintaining fire protection for structural members throughout construction and the lifespan of a building. This standard is applicable exclusively to laboratory settings, with an emphasis on compliance with both SI and inch-pound units as separate, non-interchangeable systems.
Key Topics
- Impact Resistance of SFRM: The primary focus is to evaluate how SFRM, including both fibrous and cementitious types, adheres to steel deck assemblies under sudden impact conditions.
- Adhesion and Durability: This method tests the SFRM’s resistance to spalling, cracking, and delamination when subjected to shock loading. These are vital indicators of its ability to remain intact and functional during anticipated building service conditions.
- Specimen Preparation: Test specimens consist of a laboratory-prepared cellular steel deck topped with concrete, simulating real-world structural conditions.
- Laboratory Procedure: The impact test is performed by dropping a weighted leather bag onto the specimen. After exposure, the physical state of the SFRM-including any cracking or separation-is thoroughly examined and reported.
- Serviceability Assessment: Data from these tests inform whether sprayed fireproofing remains effective after potential construction or occupancy impacts.
Applications
- Fire Protection Validation: Used by manufacturers, contractors, and structural engineers to validate the robustness of SFRM installations against accidental impacts during construction or building use.
- Product Testing and Certification: Facilitate regulatory compliance and performance benchmarking for SFRM products as required for project specifications or safety codes.
- Quality Assurance: Construction professionals employ this method to confirm that field-applied SFRM mirrors the laboratory-assessed performance in impact resistance and adhesion.
- Research and Development: Provides a controlled testing environment for developers of fire-resistive materials to improve formulations for greater resilience and durability.
- Regulatory Compliance: Supports building code authorities and fire safety inspectors in adopting industry-accepted methods for evaluating the fireproofing integrity of structural components.
