ASTM E736-00(2006)
(Test Method)Standard Test Method for Cohesion/Adhesion of Sprayed Fire-Resistive Materials Applied to Structural Members
Standard Test Method for Cohesion/Adhesion of Sprayed Fire-Resistive Materials Applied to Structural Members
SIGNIFICANCE AND USE
The intent of this test method is to determine a property of SFRM that may be used to provide an indication of its in-place serviceability. Satisfactory performance of SFRM applied to structural members and assemblies depends upon its ability to withstand the various influences that may occur during construction and during the life of the structure, as well as upon its satisfactory performance under fire conditions.
SCOPE
1.1 This test method covers a procedure for measuring the cohesion/adhesion or bond strength (tensile) perpendicular to the surface of sprayed fire-resistive material (SFRM) applied to rigid backing. These fire-resistive materials include sprayed fibrous and cementitious materials. The test method is applicable to both laboratory and field procedures as indicated in Section 7.
1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.
1.3 This standard does not purport to address all of the safety problems, 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.

8. Procedure
8.1 Apply adhesive sufficient to fill the metal or plastic cap,
and immediately place the cap against the surface of the
SFRM. Refer to Fig. 2.
8.2 Support the cap at the surface until the adhesive has
adequately cured. Wipe away any excess adhesive around the
cap before it cures, or carefully cut it away after it cures.

with a suitable adhesive. An increasing load, measured by a scale, is applied manually until failure occurs.
4. Significance and Use
