A functional and hierarchical grouping of assets that require planned preventative maintenance. The individual items in the asset classification have their own descriptions and codes.

Asset classifications are added and maintained in Supporting Data > Asset classification.
They can subsequently be selected in Maintenance Planner > Asset filters. Different methods of asset classification are used for different types of assets. If you select an asset classification at Asset filters and subsequently drill down to Definitions & schedules, only the activity definitions with assets belonging to that asset classification are displayed in the elements list.
