(Test Method)Standard Test Method for Air Erosion of Sprayed Fire-Resistive Materials (SFRMs) Applied to Structural Members
Standard Test Method for Air Erosion of Sprayed Fire-Resistive Materials (SFRMs) Applied to Structural Members
SIGNIFICANCE AND USE
It is the intent of this test method to determine properties of SFRM that may be used to provide an indication of 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 performance under fire conditions.
Air erosion tests on SFRMs are conducted to evaluate the behavior of the SFRM when subjected to plenum air streams during normal service conditions. Such tests evaluate the resistance to dusting, flaking, spalling, and delamination of the SFRM.
SCOPE
1.1 This test method covers a procedure for determining the effect of an air stream upon sprayed fire-resistive materials (SFRMs). These SFRMs include sprayed fibrous and cementitious materials. The test method is applicable only to laboratory procedures.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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 and health practices and determine the applicability of regulatory limitations prior to use.
