Setting Emissivity (Reference)

Quantity of infrared radiation emitted from objects depends on the objects�f material, surface conditions, measuring temperatures and so on. The table below shows emissivity of some objects. Please note that these values are just for reference. Please also refer to the estimated emissivity using the separately sold black body tape.

Material Emissivity Water, Ice 0.98 Soil 0.92 to 0.96 Concrete (wet) 0.96 to 0.98 Concrete (dry) 0.91 to 0.95 Ceramics 0.85 to 0.95 Stone, Asbestos 0.92 Plastics 0.90 to 0.95 Rubber (black) 0.95 Wood 0.98 Paper 0.92 Cloth, Fabric (colored) 0.95 Leather, Fur 0.96 Human skin 0.99 Vegetable, Fruit 0.98 Dough 0.98 Meat 0.98 Copper oxide 0.5 to 0.6 Ferric oxide 0.7 to 0.8 Painted surface 0.8 Tile 0.9
