ISO 15926-2:20 03规定了用于计算机表示加工厂技术信息的概念数据模型。以下活动所需的信息在ISO 15926-2:20 03的范围内: 生产、加工和运输工艺材料的要求规范；生产和加工所需材料所需功能的规格，包括以下内容:碳氢化合物工艺和调节系统、注入气体和水的调节和注入系统、石油和天然气产品运输系统、安全和控制系统、发电和供应系统、蒸汽产生和供应系统、结构、建筑物和住宿；提供所需生产和加工功能的材料和设备的规格和选择，包括有关市场上可用材料和设备的信息；厂房设备安装调试；生产和工艺操作，包括工艺条件和消耗、产量和工艺材料质量；设备的维护和更换。 以下活动超出了ISO 15926-2:20 03的范围: 建造建筑物、生产设施和设备。 ISO 15926-2:20 03是ISO 15926的一部分，ISO 15926是表示加工厂生命周期信息的国际标准。该表示由设计为与参考数据结合使用的通用概念数据模型指定:表示多个用户、过程工厂或两者共有的信息的标准实例。加工厂参考数据的使用和定义是ISO 15926第4、5和6部分的主题。

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.
