Full title and description

Industrial automation systems and integration — Product data representation and exchange — Part 233: Application protocol: Systems engineering. This ISO application protocol (AP233) defines a standardized data representation and exchange model for systems engineering information to support interoperability between tools and organisations involved in the design and lifecycle of engineered systems.

Abstract

AP233 specifies the context, scope and information requirements for systems engineering data across development stages. It provides an information model to represent system definitions, interfaces and related engineering artefacts, and is applicable to a wide range of engineered products including aircraft, cars, ships, railways and plant.

General information

• Status: Published (international standard, confirmed).
• Publication date: 13 November 2012 (Edition 1, 2012-11).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 25.040.40 (Industrial process measurement and control).

Scope

The standard defines an application protocol within the ISO 10303 (STEP) family for representing systems engineering data. It covers information requirements and the information model needed to capture systems definitions, interfaces and associated engineering data across multiple lifecycle and development stages, enabling standardized exchange between systems engineering tools and processes. AP233 replaces the earlier ISO/PAS 20542 deliverable and is intended for any engineered system domain (aerospace, automotive, marine, rail, plant, etc.).

Key topics and requirements

• Formal information model for systems engineering artefacts (requirements, architecture, interfaces, configurations).
• Definitions of context, scope and information requirements for different development stages.
• Interoperability and exchange rules to enable tool-to-tool data transfer and long-term data retention.
• Mapping of systems engineering concepts into the STEP/AP architecture to integrate with product data models.
• Replacement of ISO/PAS 20542:2006 and alignment with other ISO 10303 application protocols where appropriate.

Typical use and users

Typical users are systems engineers, model-based systems engineering (MBSE) practitioners, PLM and systems-integration tool vendors, aerospace/defence/automotive/railway/plant engineering organisations, and standards or data-governance teams who need to exchange structured systems engineering data between systems and organisations.

Related standards

Part of the ISO 10303 (STEP) family of standards (product data representation and exchange). It supersedes ISO/PAS 20542:2006. Implementers commonly consider other ISO 10303 application protocols and STEP resources (and domain-specific APs) when integrating AP233 into a broader data-exchange or PLM strategy.

FAQ

Q: What is this standard?

A: ISO 10303-233:2012 (AP233) is an ISO application protocol within the STEP family that specifies an information model and exchange constructs for systems engineering data.

Q: What does it cover?

A: It covers the context, scope and information requirements for representing systems engineering artefacts (requirements, architectures, interfaces, configurations) across development stages and supports exchanging that information between tools and organisations.

Q: Who typically uses it?

A: Systems engineers, MBSE practitioners, PLM/tool vendors, systems integrators, and engineering organisations in sectors such as aerospace, automotive, maritime, rail and industrial plant.

Q: Is it current or superseded?

A: ISO 10303-233:2012 is the published, confirmed edition (first edition 2012). The ISO record shows the publication in November 2012 and that the standard has been reviewed and confirmed (most recently confirmed in 2024), so this edition remains current.

Q: Is it part of a series?

A: Yes — it is Part 233 of the ISO 10303 family (commonly called STEP), which contains multiple application protocols and resource parts for product data representation and exchange.

Q: What are the key keywords?

A: Systems engineering, AP233, STEP, data exchange, interoperability, MBSE, system interfaces, product data representation.
