### Use Definitions

An IfcEquipmentStandard is assigned a set of classification notations (through the IfcRelAssociatesClassification class within the IfcKernel schema) that determine the types of equipment that fulfill the requirements of the standard. In order to use the equipment standard class, a classification of equipment items must have been established. This does not mean that each individual equipment item needs to have a classification notation although this is considered to be desirable. Examples of equipment items that might fall within an equipment standard include number and type PC's and connections, task lighting, pictures etc.

An equipment standard is assigned to one or several persons or organizations (like a work group or department) through the IfcRelAssignsToControl relationship via the Controls inverse attribute.
