Some combinations of measurement values are reasonably provided together. This specification standardizes some of those combinations by defining interfaces containing all those combinations. Applications may implement those interfaces and thereby provide the combinations of measurement values.
Standardized interfaces are defined in 7.1.3 An example, how standardized interfaces are used is shown in Figure 10. The interface can either be used directly on an instance, like on MyMeasurementPoint, or on a ObjectType like on MyEnergyMeasurementType.
