ISO 15926-2:2003 specifies a conceptual data model for computer representation of technical information about process plants. The information required by the following activities is within the scope of ISO 15926-2:2003:

• specification of requirements to produce, process, and transport process materials;
• specification of functions required to produce and process the required materials, including the following:
  • hydrocarbon process and conditioning systems,
  • injected gas and water conditioning and injection systems,
  • oil and gas product transport systems,
  • safety and control systems,
  • electricity generation and supply systems,
  • steam generation and supply systems,
  • structures,
  • buildings and accommodation;
• specification and selection of materials and equipment to provide the required production and processing functions, including information about market available materials and equipment;
• installation and commissioning of plant equipment;
• production and process operations, including process conditions and consumption, yields and quality of process material;
• maintenance and replacement of equipment.

The following activities are outside the scope of ISO 15926-2:2003:

• construction of buildings, production facilities and equipment.

ISO 15926-2:2003 is a part of ISO 15926, an International Standard for the representation of process plant life-cycle information. This representation is specified by a generic, conceptual data model designed to be used in conjunction with reference data: standard instances that represent information common to a number of users, process plants, or both. The use and definition of reference data for process plants is the subject of Parts 4, 5 and 6 of ISO 15926.
