 | Thermal Expansion Coefficient Measure |
 | Mesure du cefficient de dilatation thermique |
IfcThermalExpansionCoeffientMeasure is a measure of the thermal expansion coefficient of a material, which expresses its elongation (as a ratio) per temperature difference. It is usually measured in 1/K. A positive elongation per (positive) rise of temperature is expressed by a positive value.
