Prefabricated gypsum plasterboard panels with a cellular paperboard core. Definitions, requirements and test methods Ingestion-build-84997 road signs and buildings) and1 Scope This European Standard specifies the characteristics and performance of prefabricated panels made of gypsum plasterboard facings complying with EN 520 and a cellular paperboard core intended to be used as a lightweight partition, lining and encasement for general use in buildings. This standard covers the following characteristics: reaction to fire, water vapour permeability, flexural strength (breaking load) and thermal resistance to be
