ASTM E937/E937M-93(2020)

Standard Test Method for Corrosion of Steel by Sprayed Fire-Resistive Material (SFRM) Applied to Structural Members

SIGNIFICANCE AND USE
5.1 It is the intent of this test method to determine relative corrosive properties of direct applied SFRM that provides an indication of serviceability. Satisfactory performance of SFRM applied to structural members and assemblies depends upon its ability to withstand the various influences that occur during the life of the structure, as well as upon its satisfactory performance under fire conditions.  
5.2 This test method evaluates the relative corrosion of steel induced by SFRM and determines whether the presence of SFRM increases, decreases, or has no effect on the corrosion characteristics of steel.
SCOPE
1.1 This test method covers a procedure for measuring the corrosion to steel induced by sprayed fire-resistive material.  
1.2 These SFRMs include sprayed fibrous and cementitious materials applied directly in contact with the structural members.  
1.3 This test method is applicable only to laboratory procedures.  
1.4 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.  
1.5 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.  
1.6 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.
