Standard Test Method for Effect of Deflection on Sprayed Fire-Resistive Material Applied to Structural Members
SIGNIFICANCE AND USE
4.1 The intent of this test method is to determine properties of direct-applied SFRM that may be used to provide an indication of serviceability. Satisfactory performance of fire-resistive material applied to structural members and assemblies depends upon its ability while in place to withstand the various influences that may occur during the life of the structure, as well as upon its satisfactory performance under fire tests.
4.2 This test method measures the behavior of SFRM when subjected to deflection and evaluates such phenomena as spalling and delamination under bending stress. 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 deflection on sprayed fire-resistive material (SFRM) applied to steel 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 E759/E759M-92(2023): Standard Test Method for Effect of Deflection on Sprayed Fire-Resistive Material Applied to Structural Members provides a laboratory procedure to evaluate the serviceability of sprayed fire-resistive materials (SFRMs) applied to structural steel deck systems. This test method is critical for determining how SFRMs-such as sprayed fibrous and cementitious materials-perform under conditions that simulate structural deflection and bending stress.
Ensuring that SFRMs remain intact and adhere reliably under expected service conditions is essential for maintaining fire resistance and structural safety throughout a building’s lifecycle. This standard is widely recognized in construction, engineering, and fire safety industries as a benchmark for quality and durability testing of fireproofing applications.
Key Topics
- Purpose: To measure the behavior of SFRM under deflection, specifically assessing spalling (breaking off of material) and delamination (separation from the substrate).
- Test Conditions:
- SFRM is applied to a steel deck specimen following manufacturer-recommended methods.
- The test specimen undergoes controlled deflection by applying a vertical load.
- Observations are made for material integrity, spalling, and delamination as a result of the induced bending stress.
- Relevance: Evaluates the ability of sprayed fireproofing materials to withstand normal building movements and maintain their fire-resistive properties during service life.
- Serviceability Indicator: The method provides a qualitative indication of whether SFRM will remain adhered and functional under anticipated conditions, supporting building safety and code compliance.
- Measurement Units: Procedures can be conducted using either SI units or inch-pound units, but these should not be intermixed within a test.
Applications
- Building Construction and Engineering: Used by architects, engineers, and contractors to qualify fire-resistive materials for structural steel protection.
- Product Certification: Essential for manufacturers and suppliers of SFRM to demonstrate product performance and durability in conditions simulating real-world use.
- Fire Safety Evaluations: Assists regulatory bodies and safety assessors in verifying that applied SFRM meets legal and code requirements related to fire resistance and ongoing material performance.
- Maintenance and Retrofit Assessments: Provides guidance for inspecting in-place SFRMs during building modifications and retrofits, ensuring that fireproofing will not be compromised by building movement or structural adjustments.
Related Standards
When using or specifying ASTM E759/E759M-92(2023), the following related ASTM standards are often referenced for comprehensive fire resistance and material quality evaluation:
- ASTM E605/E605M: Test Methods for Thickness and Density of Sprayed Fire-Resistive Material (SFRM) Applied to Structural Members.
- ASTM E84: Standard Test Method for Surface Burning Characteristics of Building Materials.
- ASTM E119: Test Methods for Fire Tests of Building Construction and Materials.
Practical Value
Implementing ASTM E759/E759M ensures that sprayed fire-resistive materials applied to steel structures can maintain their integrity and protective qualities under deflection-supporting increased safety, performance reliability, and compliance with international fire resistance standards. This benefits not only product manufacturers and builders but also inspectors, regulators, and building owners concerned about long-term fire protection and structural stability.
