ASTM E761/E761M-92(2020) pdf free download.Standard Test Method for Compressive Strength of Sprayed Fire-Resistive Material Applied to Structural Members Active Standard ASTM E761 / E761M | Developed by Subcommittee: E06.21.
ASTM E761/E761M-92(2020) 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.
The compressive strength of SFRM applied to a steel sheet is determined by applying a crushing load normal to the surface of the specimen. This test method measures the stress at 10 % deformation or at failure, whichever is smaller.
ASTM E761/E761M-92(2020) 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.
ASTM E761/E761M-92(2020) requires the application of SFRM in accordance with manufacturers’ published instructions. The apparatus, materials, and procedures used to apply the SFRM for this test shall be representative of application in the field.
