    Significance and Use

    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.

    This test method measures the compressive strength of SFRM and is a measure of the resistance to deformation under a compressive load. It is an indication of the ability of SFRM to remain in place and resist removal during anticipated service conditions.

    1. Scope

    1.1 This test method covers a procedure for measuring the compressive strength of sprayed fire-resistive material (SFRM) applied to a rigid substrate. These fire-resistive materials include sprayed fibrous and cementitious materials applied directly in contact with these structural members. The test method is applicable to laboratory procedure.

    1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.

    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 and health practices and determine the applicability of regulatory limitations prior to use.
