ASTM E937结构构件上喷涂防火材料对钢腐蚀性试验方法

ASTM E937 Standard Test Method for Corrosion of Steel by Sprayed Fire-Resistive Material (SFRM) Applied to Structural Members
ASTM E937 结构构件上喷涂防火材料对钢腐蚀性试验方法

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.
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.

1. 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 SI units are to be regarded as the standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.
1.5 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 and health practices and determine the applicability of regulatory limitations prior to use.
