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 .
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 E 119 and E 84.
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 for information only.
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.

be of sufficient length for the thickness of the material to be measured. This gage shall be graduated in 1 mm ( ⁄16 in.) intervals.
This disk shall be perpendicular to the needle at all times and shall have a friction device to grip the pin unless purposely moved.

The disk diameter shall be a minimum of 22 mm ( ⁄8 in.) and a maximum of 30 mm (1 ⁄8 in.), to permit contact with the surface
of the specimen to be measured. For materials not readily penetrated by the depth gage, see 8.1.2.1 and Note 2.

7. Test Specimen
7.1 Laboratory Tests:
7.1.1 The test specimens shall be SFRM applied to 1.5 mm (0.06 in. (16 ga.)), 400 by 400 mm (16 by 16 in.) bare or galvanized
steel plates.
7.1.2 The specimens shall be conditioned for a period of not less than 72 h at room temperature, 20° 6 5°C (68°6 9°F) and
a relative humidity not greater than 60 %, until successive weight readings, taken at 24 h intervals, differ by less than 1 %.
7.2 Field Tests:
7.2.1 As an alternate to 7.1.2, the specimens shall be force dried at a temperature of 43° 6 6°C (109° 6 10°F) and a relative
humidity not greater than 60 % until successive readings, taken at 8 h intervals, differ by less than 1 %.
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.) increments as
shown by the position of the sliding clip indicator.
8.1.2.1 Forthepurposeofaveragingmeasurements,anymeasurement6mm( ⁄4in.)ormore,overtherequireddesignthickness,
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

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.) 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.) 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.)
