C. Treatment Time Limit

The Treatment Time Limit (300A,062E) is the maximum time span allowed to deliver a single fraction of this RT Radiation SOP Instance. The behavior of the treatment delivery device on exceeding the Treatment Time Limit is up to the implementation. Treatment is expected to terminate upon reaching the Treatment Time Limit (300A,062E) independent of the Meterset and so this Attribute should have a value that accommodates normal variations in delivery.
