In a two-part presentation, the RAL Quality Association for Synthetic Surfaces and Artificial Turf Systems in Sports Facilities will first provide insights into the quality marks "RAL-GZ 944 Synthetic Turf Systems in Sports Facilities" and "RAL-GZ 943 Synthetic Surfaces in Sports Facilities". The second part of the presentation will then focus primarily on specific quality and testing regulations for the recycling of synthetic turf, synthetic surfaces, and elasticizing layers.
