11.4 If the floor protector being tested per 11.2 contaIns spacers to create an air space under the floor protector and also contains convective air openings that allow that air space to communicate with room air, a test box that allows the air space to naturally convect will need to be constructed. When constructing the test box, block off any air openings that would be less than 1.5 Inches from the Iloor when the floor protector is installed as intended in the home. Foff ow the remaining requirements as per 11.3.
12 RadIant Panel Test
12.1 A product shall have a flame spread index of 50 or less when tested as specified in the Standard Test Method for Surface Flammability 01 Materials Using a Radiant Heat Energy Source. ASTM El 62. A product complying with the Standard Test Method for Behavior of Materials in a Vertical Tube Furnace at 750°C, ASTM El 36. is considered as having a flame spread index of 50 or less.
13 Burning Brand Test for Floor Protectors
13.1 General
13.1.1 A floor protector shall remain intact and shall not flame on either its topside or underside when exposed to a burning wood brand as described in I 2 — 13.5 A floor protector in which all component materials comply with the Standard Test Method for Behavior of Materials In a Vertical Tube Furnace at 750°C, ASTM E136. is considered as complying with these requirements.
13.2 SIze and construction of brand
13.2.1 The wood brand is to consist of a grid, 5-3/4 inch by 6 by 2.1/4 inches (146 mm by 150mm by 57 mm), made of kiln-dried Douglas fir lumber that is free from knots and pitch pockets. The brand is to be made of 18 strips of lumber 3/4 inch by 3/4 inch (19.1 mm by 19.1 mm) square and 6 inches (150 mm) long, placed in three layers of six strips each, with strips spaced 1/4 inch (6.4 mm) apart. The strips are to be placed at right angles to those In adjoining layers and are to be nailed, using 1-1/2 Inch (38.1 mm) long, 16 AWG nails, or stapled, using 16 AWG steel wire staples having a 7132-inch (5.6-mm) crown and 1-1/4 inch (31.8-mm) legs, at each end of each strip on one face, and in an “X’ pattern on the other face. Prior to exposing the Hoar protector to the burning wood brand, the brand Is to be conditioned in an oven at 40 to 49°C (105 to 120°F) for at least 24 hours. The dry weight of the finished brand is to be 500 ±50 grams at the time of ignition. See Figure 13.1.
13.4 Test conditions
13.4.1 The floor protector is to be mounted such that the underside of the floor protector can be observed. The burning brand is to be placed on the surface of the floor protector at the location considered most vulnerable with respect to ignition of the floor protector.
13.5 Duration of test
13.5.1 The test is to continue until the brand is consumed and until all evidence of flame, glow, and smoke has disappeared from both the exposed surface of the material being tested and the underside of the floor protector, or until unacceptable results occur, but not more than 1-1/2 hours.
14 Impact and Strength Test
14,1 A floor protector, after being subjected to the impacts and loading specified in 14.2 and 14.3. shall show no deformation to the insulating material which would impair insulating charactenstics nor shall any covering material be damaged to the extent that insulating material is exposed.
14.2 An air space or air pockets of a product designed with an insulating air space shall not be reduced after being subjected to the impacts and loading specified in 14.3 and 14.4.
14.3 The floor protector is to be subjected to three successive impacts from a 5 inch (127 mm) diameter hardwood log. 18 inches (457 mm) long, weighing 12 pounds-mass (5.4 kg). and dropped from a height of 48 inches (1.22 mm) with its major axis parallel, perpendicular, and at a 45 degree angle to the surface of the floor protector.
14.4 The floor protector Is to be subjected to a 600 pounds-force (Ibf) (272 N) static load applied to a 1 square-inch (6.45 cm2) area for 30 minutes.
