Test Procedure:
The Intermittent-Flame test is applied to the surface for an intermittent length of time with constant airflow. The Burning-Brand is placed on the top of the BIPV material for 90 minutes. The Spread of Flame test is conducted by the direct placement of fire and wind for various amounts of time depending on the Class A, B, or C roof system.
End Result:
The Intermittent-Flame and Burning-Brand passing the test is identified by penetration or flaming on the underside of the roof deck. The Spread of Flame test is measured by surface ignition over a period of time based on Class A, B, or C roof system.
Preparation:
1. Do intermittent fire, wood burning test substrate should be made according to the following requirements.1m wide and 1.3 m long with 1 ponderosa or ponderosa pine slats with a moisture content of 8% to 12% required to be free of large pine joints, burrs, rot, or resins with unscarred edges.Single strip nominal size: 19.1mm 184mm, smooth edges.
2. For grade C wood burning tests, The width of the wood shall be just above the gap in the center of the wood.The strip spans the narrow side of the base plate and is 6.4mm apart. It is securely nailed on the strip with a nominal section of 38mm 89mm and left with margin.The substrate shall be flat and unified.
3. When the top piece is used on plywood of the minimum thickness provided by the client, it shall be studied.Douglas fir plywood has panels and backs.Plywood substrate shall have 3.2mm transverse and longitudinal joints, and all longitudinal joints shall be located above the 38mm 89mm batten.Horizontal seams may also be made of such laths if recommended by client.
4. Plywood substrates used in grade A and grade B wood-burning tests shall have parallel horizontal joints 572mm from the leading edge of the substrates.The class A test substrate shall have A seam at the center of the substrate and extending upward from the horizontal seam.Class B test substrates shall have two vertical joints extending from horizontal joints 254mm parallel to both sides.Class C test substrates shall have five horizontal joints with a 3.2mm gap between them.
