ASTM E 761/E761M : 1992 : R2020

1.1This 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.

1.2The 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.

1.3This 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.

1.4This 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.
