8.10.4.11 Pset_MaterialWater

8.10.4.11.1 Semantic definition

A set of extended material properties for of water typically used within the context of building services and flow distribution systems.

Name	Property Type	Data Type	Description
IsPotable	IfcPropertySingleValue	IfcBoolean	If TRUE, then the water is considered potable.
Hardness	IfcPropertySingleValue	IfcIonConcentrationMeasure	Water hardness as positive, multivalent ion concentration in the water (usually concentrations of calcium and magnesium ions in terms of calcium carbonate).
AlkalinityConcentration	IfcPropertySingleValue	IfcIonConcentrationMeasure	Maximum alkalinity concentration (maximum sum of concentrations of each of the negative ions substances measured as CaCO3).
AcidityConcentration	IfcPropertySingleValue	IfcIonConcentrationMeasure	Maximum CaCO3 equivalent that would neutralize the acid.
ImpuritiesContent	IfcPropertySingleValue	IfcNormalisedRatioMeasure	Fraction of impurities such as dust to the total amount of water. This is measured in weight of impurities per weight of water and is therefore unitless.
DissolvedSolidsContent	IfcPropertySingleValue	IfcNormalisedRatioMeasure	Fraction of the dissolved solids to the total amount of water. This is measured in weight of dissolved solids per weight of water and is therefore unitless.
PHLevel	IfcPropertySingleValue	IfcPHMeasure	Maximum water PH in a range from 0-14.
