(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
4.1 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 either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
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.

7. Test Specimen
7.1 Laboratory Tests:
7.1.1 The SFRM shall be applied at a thickness of 12 mm to 25 mm ([ ⁄2 in. to 1 in.)1 in.] to the 300 by 300 mm (12[12 by

7.1.2 Condition the specimen at room temperature (20 6 10°C (68 6 18°F)).[68 6 18°F]). After 72 h, samples may be force
dried in a drying oven at 43 6 6°C (110 6 10°F),[110 6 10°F], and a relative humidity not greater than 60 % until successive
weight readings, taken at 8 h intervals, differ by less than onwpercent.
