SECTION 4 MATERIAL SOURCE/INSTALLATION

The test material was not sampled by a representative of Intertek and submitted by the client. The test material was applied to the plywood decks by the client. The test specimen was submitted to Intertek directly from the client. Samples were not independently selected for testing. Intertek has not verified the composition, manufacturing techniques or quality assurance procedures. SECTION 5 SPECIMEN DESCRIPTION

The plywood decks were constructed by Intertek technicians according to the specifications of test standard ASTM E108, 2018 Edition, “Standard Test Methods for Fire Tests of Roof Coverings.” The test material was applied by the client.

Moisture Content: Moisture content of the lumber was verified prior to testing to be within the limits of the standard.

SECTION 5 (Continued) SPECIMEN DESCRIPTION

The samples are described in more detail in the table below.

DECK # DECK TYPE DECK SURFACE

SYSTEM (Systems are described in assembly from wood deck to top surface)

1-4 Class A BB 15/32” AC grade Douglas Fir plywood

Batten Strips*: Pressure treated 1 in. x 4 in. dimensional batten

strips were installed at the pre-determined locations of the

middle of the cement board sections. The furring strips were the

full width of the deck and fastened to the plywood deck with

#7 x 2 in. long exterior wood screws.

Cement Board*: 24 in. long x full deck width x 5/8 in. thick

National Gypsum PermaBase® Cement Board sections were

installed over the batten strips. The sections were placed on an

angle so that the end toward the simulated eave was resting on

the deck surface and the other end of the board point to the

simulated peak was about 1-1/2 in. above the deck

surface. Pressure treated nominal 1 in. x 4 in. dimensional batten

strips were installed on between the overlap of the board making

contact with the deck surface and below the board 1-1/2 above

the deck surface. The batten strips between the boards were

fastened through the boards below and into the test deck with

#8 x 2-1/2 in. long exterior wood screws. The boards were

fastened to the batten strips between the boards and the

midpoint with 1-5/8 in. long cement board screws.

Coating: Prior to coating installation, AcryLabs 2400 Brushable Sealant was used to back fill gaps the screw head indentations in the PermaBase® cement board as needed. One layer of AcryLabs 2100B Base Coat was applied to the full deck surface. Once the AcryLabs 2100B Base Coat was applied, one layer of Acrylabs Mesh reinforcing fabric was installed. A single layer of AcryLabs 2100B Base Coat was then applied over the Acrylabs Mesh, and 2 layers of 2100 AcryLabs Finish Coat were applied to finish the coating installation. The total application dry film thickness of the Acrylabs system was of 45 mils (0.045”).

5-6 Class A SOF 15/32” AC

grade Douglas Fir plywood

Same as above.

7-8 Class A IF 15/32” AC

grade Douglas Fir plywood

Same as above.
