The element <thresholdInterval> contains any (one or more) threshold interval information that is relevant to the task. It is populated in the format of threshold or threshold interval value. For example 25 followed by the value of the attribute thresholdUnitOfMeasure (eg, FH).Recommendation: The use of the element <thresholdInterval> can conflict with the same data given in the maintenance planning information data modules. A close coordination must be taken if the same data is given in both the procedure and the maintenance planning information. It is recommended to use the maintenance planning information in preference of the element <thresholdInterval> in each procedural data module.
