7.4.4.23.3 Properties

Name Property Type Data Type Description
OverallDiameter IfcPropertySingleValue IfcPositiveLengthMeasure

The overall diameter of a object.

The overall diameter of a core (maximum space used).

RatedVoltage IfcPropertyBoundedValue IfcElectricVoltageMeasure

The range of allowed voltage that a device is certified to handle. The upper bound of this value is the maximum.

RatedTemperature IfcPropertyBoundedValue IfcThermodynamicTemperatureMeasure

The range of allowed temperature that a device is certified to handle. The upper bound of this value is the maximum.

ScreenDiameter IfcPropertySingleValue IfcPositiveLengthMeasure

The diameter of the screen around an object (if present).

CoreIdentifier IfcPropertySingleValue IfcIdentifier

The core identification used Identifiers may be used such as by color (Black, Brown, Grey) or by number (1, 2, 3) or by IEC phase reference (L1, L2, L3) etc.

SheathColours IfcPropertyEnumeratedValue PEnum_CoreColoursEnum

Colour of the core (derived from IEC 60757). Note that the combined color 'GreenAndYellow' shall be used only as Protective Earth (PE) conductors according to the requirements of IEC 60446.

Weight IfcPropertySingleValue IfcMassMeasure

Total weight of object

Weight of core kg/km.

UltimateTensileStrength IfcPropertySingleValue IfcForceMeasure

Indicates the maximum stress that a material or element can withstand before breaking while being stretched or pulled.

SelfExtinguishing60332_1 IfcPropertySingleValue IfcBoolean

Self Extinguishing cable/core according to IEC 60332.1.

SelfExtinguishing60332_3 IfcPropertySingleValue IfcBoolean

Self Extinguishing cable/core according to IEC 60332.3.

HalogenProof IfcPropertySingleValue IfcBoolean

Produces small amount of smoke and irritating Deaerator/Gas.

FunctionReliable IfcPropertySingleValue IfcBoolean

Element (such as cable, bus, core) maintain given properties/functions over a given (tested) time and conditions. According to IEC standard.

Standard IfcPropertySingleValue IfcLabel

The designation of the standard applicable for the definition of the object used.

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.

LayRatio IfcPropertySingleValue IfcPositiveRatioMeasure

The ratio between lay length and the diameter of the single conductor.

MassPerLength IfcPropertySingleValue IfcMassPerLengthMeasure

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

TensileStrength IfcPropertySingleValue IfcPressureMeasure

Indicates the ability to withstand breakage apart under applied force.

YoungModulus IfcPropertySingleValue IfcModulusOfElasticityMeasure

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

ACResistance IfcPropertySingleValue IfcElectricResistanceMeasure

The resistance under AC.

StrandingMethod IfcPropertySingleValue IfcLabel

Specifies the method used to strand the cable. Stranding is the process where a particular number of stranding elements are joined together while winding them round a common axis.
