EN 15330-5, Specifications for infill material, is the immediate result of the debate on the desirability of polymeric infills and subsequent ban on the trading of intentionally added microplastics with a particle size larger than 5mm, from October 2031 onwards. When this debate started in 2020, approximately 50,000 synthetic turf fields had been installed in Europe alone. The majority of these fields were finished with a polymeric infill. With new products like corn cobs, wood chips, coated sands and olive pits entering the market which was already familiar with cork infill and infill mixtures of coconut fibres and cork, the need arose for a set of information that would help define the best alternative infill for a project. Between 2020 and 2025, Technical Committee 217 worked on a standard which, after having been revised several times, was approved and published in 2025. As protocol grants all member states six months to prepare for an introduction of a new standard, any existing standard has been withdrawn from March 2026.
