Gypsum elements for suspended ceilings. Definitions, requirements and test methods Ingestion-build-143074 Anyone involved in the provision1 Scope This European Standard specifies the characteristics and performance of factory made cast gypsum elements, for which the main intended uses are the construction of suspended ceilings under universal substrates. It covers the following product performance characteristics: reaction to fire, water vapour permeability, flexural strength (expressed as breaking load) and thermal resistance (expressed as thermal conductivity). The following
