Test Procedures The investigation was performed according to ASTM F 2157-02 "Standard Specification for Synthetic Surfaced Running Tracks". Unless otherwise noted, the temperature during the testing was ambient (about 23 C with 50% RH). Modified Vertical Deformation was tested with the Artificial Athlete Stuttgart in accordance with the procedure specified in sections 6.9 through 6.10.1 of the named standard. A 20 kg missile is dropped from a height of about 5 inch onto a spring/load cell/test foot assembly resting on the surface sample. The spring number is 40 N/mm. The responding vertical deformation in mm of the surface sample is determined and adjusted to a unified reference peak force of 1500N. The test foot has a diameter of 70mm. The resulting class is determined according to Table 1 where the results for each temperature must meet the requirement of the class. Force Reduction was tested using the Berlin Artificial Athlete acc. To sections 6.7 through 6.8.6 of the named standard. A 20kg missile is dropped from a height of 55mm onto a spring/load cell/test foot assembly resting on the surface sample. The spring number is 2000N/mm. The responding peak force of the impact is recorded and compared with the peak force resulting on a concrete floor (FR = 0 %). The more shock absorbing the surface, the higher the Force Reduction (FR) value. The resulting class is determined according to Table 1 where the results for each temperature must meet the requirement of the class. Texture Influence (Sliding Behavior) was determined using the Rotational Sliding Tester Method B acc. to the IAAF Perfomance Specifications for Synthetic Surfaced Athletic Tracks or DIN 18035-6 respectively (sections 6.11 through 6.12 of ASTM F 2157). A test foot with 4 diameter and equipped with 3 skids with leather soles runs down a spindle and rotates on the surface. From the torque caused by the friction between leather soles and the surface and the vertical load (20 kg) the Sliding Coefficient is derived. Water Permeability is not required by ASTM F 2157. It was tested following the standard EN 12 616 "Surfaces for Sports Areas; Determination of Water Infiltration Rate". A 15cm ring is placed on the surface and sealed with plastiline at its lower edge. 1000 ml of de-aired water is carefully poured onto the surface inside the ring (avoiding water to dissipate to the side). The time is determined until the water has completely seeped into the surfacing. The water column applied is 5,66 cm. The Infiltration Rate in [cm/sec] is

Spike Resistance was determined with the Spike Tester following DIN 18035-6 as stated in sections 6.21 through 6.22 of ASTM F 2157. A wheel equipped with 9 mm spikes in a random pattern (spaces between spikes about 1 ) is rolled 300 times over the surface. No more than 10 perforations per 50 sqi should occur (= Class I acc. DIN 18035-6). Flammability was determined acc. To sections 6.23 and 6.24 which specify the test method found in ASTM D 2859 "Standard Test Method for Flamma-bility of Finished Textile Floor Covering Materials". The surface is covered with a steel plate having a 200 mm diameter hole in the center. A Methenamine tablet is placed in the center of the hole and ignited with a match. If the fire does not extend beyond an area of 150mm (6 ) diameter the test is considered passed. The test must be carried out with 4 specimens. Tensile Properties were determined acc. to ASTM F 2157 using dumbbells cut with the specified type A die shown in Figure 6 of the standard (6 inch length and 1/2 inch or 1 inch width at the center). The specimens are subjected to a constant strain of 100 mm/min until they break. The maximum force occuring during the test divided through the initial cross section is called the Tensile Strength. The Elongation at Break is the maximum elongation in [mm] referred to the initial distance (gage length) of the test marks on the sample (2 ) in [%]. Weathering is performed acc. to sections 6.19 through 6.20 of ASTM F 2157 using Practice ASTM G 154. Samples are exposed for 1000 h to UVA radiation and 4-h cycles of light and water. After this conditioning process, the samples are subjected to a tensile strength test. Tensile Strength and Elongation at Break are required to remain in the same class designation and shall not be reduced by more than 25% of the initial, unexposed sample. Thickness is determined acc. to ASTM F 2157 following the procedure in sections 6.5 through 6.6. the overall thickness, which includes the surface texture is determined with the specified device after which a plug is cut and abraded as described. The reduction in thickness is determined and subtracted from the overall thickness resulting in the absolute thickness. The requirements are listed by class in Table 1 of the standard.

Conclusion The synthetic surfacing product tested achieved a rating of Class A and complied with all requirements of ASTM F 2157-02 in respect to Class A surface systems. The test results listed above describe the properties of the submitted sample. They apply to the product in general if the product is manufactured/installed using the same material components and the same installation technique as used with the sample tested. The quality of the EPDM granules used for the texture must be proven by a separate report. Dipl.Ing. H.J. Kolitzus
