Germany: BASF has adopted the voluntary Keymark certification scheme for its Styrodur insulation boards made from extruded polystyrene (XPS). The decision follows the decision by the German government to drop the Ü mark for harmonised building products in late 2016. BASF has decided to use Keymark scheme to show that the product has been approved for use in Germany. It is a voluntary product certification awarded by Din Certco, a TÜV Rhineland company in cooperation with the German Institute for Standardisation (DIN).
