ISO 15926-1:2004

Overview

ISO 15926-1:2004 - "Industrial automation systems and integration - Integration of life-cycle data for process plants including oil and gas production facilities - Part 1: Overview and fundamental principles" - defines the purpose, scope and fundamental principles for representing and exchanging process-plant life‑cycle information. Part 1 provides a high‑level description of the ISO 15926 family, explains the conceptual data model approach, and sets out requirements for reference data, registration, maintenance and conformance. It is intended for technical managers and implementers evaluating ISO 15926 for plant data integration projects.

Key topics and requirements

• Representation of life‑cycle data: Defines a generic, conceptual model to represent engineering, construction and operation information for process plants (including oil & gas, refining, power generation, chemicals, pharmaceuticals, food).
• Reference data: Requires use of standardized reference data (common instances) to enable consistent meaning across projects and organizations.
• Architecture and conceptual models: Describes architecture principles (including a three‑schema view) and how conceptual data models support shared databases or data warehouses.
• Templates and data exchange: Covers templates for context‑specific data exchange and mapping those templates to the conceptual model.
• Registration & maintenance: Specifies procedures for registration, governance and maintenance of reference data libraries.
• Conformance: Defines how exchange files and system interfaces (exchange file interfaces and APIs) can comply with the standard.
• Relationship to other standards: Explains interplay with ISO 15926-2 (data model) and other industrial data standards.

Practical applications

ISO 15926-1 is used to plan and justify implementation of life‑cycle data integration projects for process plants. Typical applications:

• Enabling consistent handover of engineering data from design to operations.
• Creating a shared plant data repository or data warehouse for multi‑disciplinary use.
• Standardizing component and equipment specifications for procurement and asset management.
• Supporting concurrent engineering, vendor integration and long‑term plant modification planning.
• Improving safety, regulatory reporting and operational efficiency by making plant information computer‑processable and interoperable.

Who uses this standard

• Plant owners and operators
• Engineering, procurement and construction (EPC) firms
• Systems integrators and software vendors (PLM/asset info systems)
• Maintenance and reliability engineers
• Regulatory bodies and data stewards
• Technical managers assessing data‑integration strategies

Related standards

• ISO 15926-2 (Data model) - the conceptual model implementation
• ISO 10303 (STEP) family - product data representation and exchange
• ISO 13584 (Parts library)
• ISO/IEC 8824-1, ISO 10303-21/22/28 - ASN.1, STEP encoding and XML representations
