Description

IsPotable

P_SINGLEVALUE / IfcBoolean

Is Potable

If TRUE, then the water is considered potable.

Hardness

P_SINGLEVALUE / IfcIonConcentrationMeasure

Hardness

Water hardness as positive, multivalent ion concentration in the water (usually concentrations of calcium and magnesium ions in terms of calcium carbonate).

AlkalinityConcentration

P_SINGLEVALUE / IfcIonConcentrationMeasure

Alkalinity Concentration

Maximum alkalinity concentration (maximum sum of concentrations of each of the negative ions substances measured as CaCO3).

AcidityConcentration

P_SINGLEVALUE / IfcIonConcentrationMeasure

Acidity Concentration

Maximum CaCO3 equivalent that would neutralize the acid.

ImpuritiesContent

P_SINGLEVALUE / IfcNormalisedRatioMeasure

Impurities Content

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

P_SINGLEVALUE / IfcNormalisedRatioMeasure

Dissolved Solids Content

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

P_SINGLEVALUE / IfcPHMeasure

PHLevel

Maximum water PH in a range from 0-14.
