(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
5.1 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 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.
1.5 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.

FIG. 1 Thickness Gage

E605/E605M − 93 (Reapproved 2015)
8. Procedure
8.1 Thickness:
8.1.1 Selected areas to be measured for thickness shall be a predetermined, repetitive pattern to ensure obtaining representative
average thickness.
8.1.2 Determine the thickness by inserting the penetrating pin of the thickness gage perpendicular to and through the SFRM,
to the substrate. When the point of the pin touches the substrate, move the sliding disk to the SFRM surface with sufficient force
on the disk to register the average plane of the surface. Withdraw the gage to read the thickness in 1 mm ([ ⁄16 in.)in.] increments
as shown by the position of the sliding clip indicator.
8.1.2.1 For the purpose of averaging measurements, any measurement 6 mm ([ ⁄4 in.)in.] or more, over the required design
thickness, shall be recorded as the design thickness plus 6 mm. No individual measured thickness shall be more than 6 mm less,
or more than 25 % less, than the required design thickness.
NOTE 1—Specific fire resistance rating criteria for beams, trusses, and columns may allow for a reduced thickness on flange tips. These thicknesses
are to be averaged apart from other sections of the structural member. Also, some fire rating assemblies have different thickness requirements for crests
and valleys of floor decks and should be averaged apart.
NOTE 2—Medium and high density SFRM may be too hard to test for thickness by standard procedure. It is recommended to check thicknesses
immediately after application, and before curing.
The applicator shall adjust the thickness of the freshly applied SFRM to yield thickness after cure, in accordance with the SFRM manufacturer’s
recommendations.
If the product is cured and too hard to insert the thickness gage, drill small diameter holes into the product just large enough to accommodate the
thickness gage pin. The thickness gage is then inserted into these holes and thickness is determined by the standard procedure. These holes are to be closed
off immediately following the test using the same SFRM.
8.1.3 Conducting Thickness Testing—One bay per floor or one bay for each 10 000 ft , whichever provides the greater number
of tests. Thickness determinations for the following structural elements shall be conducted in each randomly selected bay: one
selected area of metal deck, concrete slab, or wall section; one column; and one beam (joist or truss).
NOTE 3—The applicable building code governs. Consult the applicable building code for exact requirements and tolerances.
8.1.4 Tests for the Deck and Wall Section:
8.1.4.1 Flat Decks—In the preselected area, lay out a 300 mm (12 in.)[12 in.] square. Take four random symmetrical
measurements within that square and report as an average. (See Note 1.)
8.1.4.2 Fluted Decks—In the preselected area, lay out a 300 mm (12 in.)[12 in.] square. Take four random symmetrical
measurements within that square, one each of the following: valley, crest, and sides, and report as an average. (See Note 1.)
