comment: An identifiable characteristic that represents how the System operates under the specified Conditions. May describe power ranges, power sources, standard configurations, attachments and the like.

comment: Describes normal OperatingProperties of a System under some specified Conditions. For example, to the power requirement or maintenance schedule of a System under a specified temperature range. In the absence of OperatingProperties, simply describes the Conditions in which a System is expected to operate. The System continues to operate as defined using SystemCapability. If, however, the SurvivalRange is violated, the System is 'damaged' and SystemCapability specifications may no longer hold.

Precision
type: Class
subclass of: System Property
comment: As a Sensor Property: the closeness of agreement between replicate Observations on an unchanged or similar Property value: i.e., a measure of a Sensor's ability to consistently reproduce an Observation, under the defined Conditions. As an Actuator Property: the closeness of agreement between replicate Actuations for an unchanged or similar command: i.e., a measure of an Actuator's ability to consistently reproduce an Actuation, under the defined Conditions.

Resolution
type: Class
subclass of: System Property
comment: As a Sensor Property: the smallest difference in the value of a ObservableProperty being observed that would result in perceptably different values of Observation Results, under the defined Conditions. As an Actuator Property: the smallest difference in the value of an Actuation command that would result in a value change of the ActuatableProperty being acted on, under the defined Conditions.

Response Time
type: Class
subclass of: System Property
comment: As a Sensor Property: the time between a (step) change in the value of an observed ObservableProperty and a Sensor (possibly with specified error) 'settling' on an observed value, under the defined Conditions. As an Actuator property: the time between a (step) change in the command of an Actuator and the 'settling' of the value of the acted on ActuatableProperty, under the defined Conditions.

Selectivity
type: Class
subclass of: System Property
comment: As a Sensor Property: Selectivity is a Property of a Sensor whereby it provides observed values for one or more ObservableProperties such that the Results for each ObservableProperty are independent of other Properties in the FeatureOfInterest being investigated, under the defined Conditions. As an Actuator Property: Selectivity is a Property of an Actuator whereby it acts on one or more ActuatableProperties such as the Results for each ActuatableProperty are independent of other Properties in the FeatureOfInterest being acted on, under the defined Conditions.

Sensitivity
type: Class
subclass of: System Property
comment: As a Sensor Property: Sensitivity is the quotient of the change in a Result of Observation and the corresponding change in a value of an ObservableProperty being observed, under the defined Conditions. As an Actuator Property: Sensitivity is the quotient of the change in a command of Actuation and the corresponding change in a value of an ActuatableProperty being acted on, under the defined Conditions.

comment: Describes survival capabilities of a System under some specified Conditions. For example, to the lifetime of a System under a specified temperature range. In the absence of SurvivalProperties, simply describes the Conditions a System can be exposed to without damage. For example, the temperature range a System can withstand before being considered damaged. The System continues to operate as defined using SystemCapability. If, however, the OperatingProperty is violated, the System is operating 'out of operating range' and SystemCapability specifications may no longer hold.
