According to John Amato, JJA Sports LLC, synthetic turf system and base system permeability test methods that existed before the development of ASTM F2898 were not ideal.
Synthetic turf drainage now has new ASTM standard
The synthetic turf industry has been plagued with drainage performance issues for many years. Huge demand has driven the industry to grow and, as more systems have been built, the potential for issues grows. With pricing competition and inexperience being factors, how well a field system drains needs to be addressed in a consistent manner. This challenge has now been addressed with the development of a new standard by ASTM International Committee F08 on Sports Equipment and Facilities.
The new standard, ASTM F2898, Test Method for Permeability of Synthetic Turf Sports Field Base Stone and Surface System by Non-confined Area Flood, is under the jurisdiction of Subcommittee F08.65 on Artificial Turf Surfaces and Systems.
According to John Amato, JJA Sports LLC, and an F08 member, synthetic turf system and base system permeability test methods that existed prior to the development of ASTM F2898 were not ideal. None were consistent and all were subject to user technique and assumption errors.
“ASTM F2898 is intended to be simple method, requiring no special testing apparatus, that would decrease the potential for user technique and assumption errors while at the same time providing intuitive and observable results,” says Amato. “The method uses a predetermined flow rate from a water source, two simple ball valves, sections of hose, a five gallon container of measured volume, stopwatch, markers to mark the extent of water migration on the surface, and a tape measure. Water source flow rate is calculated using the time it takes to fill the five gallon container of measured volume as the basis of flow for each individual test.”
Amato says that ASTM F2898 will replace un-standardized methods used by turf installers and stone base contractors to estimate the performance of their products and systems. Design engineers can use the method to test their designs and better associate stone type and installation conditions with actual performance. Testing agencies will be able to assess drainage performance of these systems for owners. The method is simple enough that owners, installers, engineers and testing agencies can all perform the test.
