* This data is from tests conducted by independent testing laboratories on a 6-inch depth of uncompressed shredded tire samples produced by four
manufacturers. The tests reported critical heights, which varied from 10 feet to greater than 12 feet. It is recommended that persons seeking to install
shredded tires as a protective surface request test data from the supplier showing the critical height of the material when it was tested in accordance with
ASTM F1292.
