8 Elevated Ambient Exposure Test
8.1 A product that incorporates operating parts having a solidus point less than 1000°F (538°C) shall comply with 8.2.
8,2 Two complete samples of the panic hardware are to be placed in the direction intended for installation in an air-circulating oven and subjected to a temperature of 4O0F (204°C) for a period of 7 hours. One of these samples shall comply with the Endurance Test, Section 6, and the Emergency Operation Test, Section 7. prior to this exposure. Following this exposure, the sample is to be cooled to room temperature, may be re-lubricated with the same material that is provided at the factory or recommended by the manufacturer, and then Is to comply with 7.2. ImmedIately upon removal from the elevated ambient, the operating parts of the second sample are to be manipulated and caused to be actuated to confirm that the assembly functions as intended at the elevated temperature and that the exposure results in no mechanical malfunction of the device. The sample shall also be visually examined for signs of degradation of materials such as melting, distortion, warpage and shrinkage. Distortion and warpage is capable of occurring to the extent that mechanical functionability is not adversely affected as determined by the manipulation of the sample as noted above.

9 Low Temperature Impact Test
9.1 A product that incorporates operating parts having a solidus point less than 1 000F (538’C) shall function as intended, show no visible signs of damage, and comply with the Emergency Operation Test, Section 7, after being tested according to 9.2 and 9.3.
9.2 A sample of the panic hardware shall be conditioned in the direction intended for installation wi a minus 3°F (minus 20°C) ambient for a period of 7 hours. Immediately following this exposure, the sample shall be installed on a test door and subjected to three impacts of 70 ft.-lb., one each on the left, center, and right areas of the crossbar or push pad. The test door is to be secured In the closed position during this test.
9.2 revised July 12. 2012
9.3 The impacts shall be produced by a swinng pendulum consisting of a solid steel door cylinder ram weighing 100 pounds (45.5 kg) with a cylindrical body and a hemispherical striking end with a diameter of 6 ±0008 inches (152 ±0.2 mm) and 13-1/4 inches (336 mm) long overall, rounded impact nose. The length of the ram is to consist of a main portion measuring 11 ±0.11 inches (279 ±2.8 mm) with the cone portion measuring 2.25 ±0.008 inches (57 ±0.2 mm). See Figure 9.1.
9.4 The ram is to be suspended from four steel cables, with two attached to the front and two to the rear of the ram. The cables are to be attached to a fixed overhead beam or the equivalent, 5.5 to 6 feet (1.7 to 1.8 m) above the center line of the ram. The two front and two rear cables are to be parallel to each other and are to be 23 to 25 Inches (58 to 63 cm) apart where they are attached to the beam. When the ram is drawn back to deliver the impact, it is to remain level, See Figure 9.2.
9.5 The ram IS to impact against a 6-Inch diameter by 2-inch thick (152-mm diameter by 51-mm thick) foamed polystyrene impact buffer having a density of 2 pounds per cubic foot (32 kg/m3) which is secured to the panic device by double-sided adhesive tape or in a similar manner.
10 General
10.1 The manufacturer’s or private labeler’s name and a distinctive type or model designation shall be plainly marked on the panic hardware assembly.
10.2 When a manufacturer produces panic hardware assemblies at more than one factory, each such
assembly shall have a distinctive marking to identity it as the product of a particular factory.
