(Test Method)Standard Test Method for Effect of Deflection on Sprayed Fire-Resistive Material Applied to Structural Members
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.
