Ageing of thermal insulation materials. Determination of the long-term change in thermal resistance of closed-cell plastics (accelerated laboratory test methods) Ingestion-build-1771971 Scope This International Standard specifies two laboratory test methods, based on slicing and scaling techniques, to determine the long term changes in the thermal resistance of closed cell (normally 90 %) cellular plastic materials that contain gases which, through diffusion processes, affect the properties of a foam with time. Using standard methods for the measurement of thermal resistance, method A consists of periodic measurements performed
