7.8.4.13.2 Applicable entities

7.8.4.13.3 Properties

Name Property Type Data Type Description
ACResistance IfcPropertySingleValue IfcElectricResistanceMeasure

The resistance under AC.

ThermalExpansionCoefficient IfcPropertySingleValue IfcThermalExpansionCoefficientMeasure

Quantity characterizing the variation with thermodynamic temperature T of the distance l between two points of a body, under given conditions (IEC 113-04-27). The ratio is defined per Kelvin.

CurrentCarryingCapacity IfcPropertySingleValue IfcElectricCurrentMeasure

Maximum value of electric current which can be carried continuously by a conductor, a device or an apparatus, under specified conditions without its steady-state temperature exceeding a specified value. Based on IEC60826-11-13. NOTE: The temperature specified value is maximum Design Ambient Temperature.

DCResistance IfcPropertySingleValue IfcElectricResistanceMeasure

The resistance under direct current and 20 degrees centigrade.

MassPerLength IfcPropertySingleValue IfcMassPerLengthMeasure

Mass per length, i.e. mass of a beam with a unit length of extrusion. For example measured in kg/m.

YoungModulus IfcPropertySingleValue IfcModulusOfElasticityMeasure

A measure of the Young's modulus of elasticity of the material.

CrossSectionalArea IfcPropertySingleValue IfcAreaMeasure

Cross section area of the phase(s) lead(s).

TorsionalStrength IfcPropertySingleValue IfcPressureMeasure

Shear strength in torsion.

TensileStrength IfcPropertySingleValue IfcPressureMeasure

Indicates the ability to withstand breakage apart under applied force.
