(Test Method)Standard Test Methods for Thickness and Density of Sprayed Fire-Resistive Material (SFRM) Applied to Structural Members
Standard Test Methods for Thickness and Density of Sprayed Fire-Resistive Material (SFRM) Applied to Structural Members
SIGNIFICANCE AND USE
Certain properties, namely thickness and density, of SFRM are basic. It is the intent of these test methods to provide procedures to determine these properties.
SCOPE
1.1 These test methods cover procedures for determining thickness and density of sprayed fire-resistive material (SFRM) used in structural assemblies. These include sprayed fiber and cementitious types. The test methods are applicable to both laboratory and field procedures, as indicated in Section 7.
1.2 These test methods require the application of SFRM in accordance with the manufacturers' published instructions. The apparatus, materials, and procedure used to apply the SFRM for laboratory tests shall be the same as is used for the construction of either of the test assemblies described in Test Methods E119 and E84.
1.3 There is no intent in these test methods to establish levels of performance.
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.
