Page 2 of 6 Report #5928US, October 19, 2004 3. Delivery of Samples Date November 11, 2003 Amount and Size of Samples 4 sections 50 cm x 50 cm Sample No. 5204 4. Test Procedures The tests reported in paragraph 5 were performed according to DIN 18035-6:1992. The climate during testing was Type 23/50 according DIN 50014 if not indicated otherwise. The test results are opposed to the requirements of DIN V 18035-6:2004-10. Since the test procedures (paragraph 5) have not changed since 1992, results can be assessed with reference to the 2004 version of DIN 18035-6. 5.

Conclusions The synthetic surfacing tested complied with the requirements of DIN V 18035-6:2004-10 in respect to Light Athletic Sports Areas. 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. Dipl.Ing. H.J.
