Full title and description

Industrial automation systems and integration — Product data representation and exchange — Part 235: Application protocol: Engineering properties and materials information. This ISO application protocol (part of the STEP / ISO 10303 family) defines the information requirements, integrated resources and application-interpreted model needed to represent engineering property data and material information used for product design, validation and related workflows.

Source: ISO catalogue and STEP family references.

Abstract

This standard specifies the use of integrated resources necessary to represent engineering property data and material information for product design, validation and other purposes. It covers descriptions of products and samples, material composition and substances, measurement and test processes, produced data values together with validity conditions, references to external standards, personnel/organization qualifications, measurement requirements and approvals. The standard excludes rules/guidelines for test methods, scheduling data and algorithms for data evaluation.

Scope

ISO 10303-235:2019 defines an application protocol to represent engineering properties and material information in a neutral, computer-interpretable form suitable for exchange, archival and integration across product lifecycle systems. Within scope are: descriptions and definitions of manufactured products and specimens; composition and substance details; descriptions of measurement and test processes and resulting data values with stated conditions of validity; references to external standards for sampling and measurement; qualifications of personnel/organisations performing measurements; specification of measurement requirements, tolerances and approvals; and location/effectivity information for measurement results. Items out of scope include procedural rules for test selection, naming/definition dictionaries for properties and methods, scheduling data and algorithms for data processing.

Scope summary paraphrased from the ISO standard text.

Key topics and requirements

• Representation of engineering property data (material properties, test results, measurement conditions and validity).
• Material composition and substance description constructs.
• Models for specimens, sampled items and testable versions of products.
• Recording of test/measurement process details, conditions, personnel and locations.
• Linking results to external normative references and approvals.
• Application Interpreted Model (AIM) and integrated resources required for exchange and archival of property and material data.

Key topics distilled from the application protocol's information requirements and annex material.

Typical use and users

This standard is used to exchange and archive engineering property and material data between CAD/CAM/CAE/PDM systems, laboratory information management systems (LIMS), quality and compliance systems, and simulation/validation tools. Typical users include product designers, materials engineers, test laboratories, manufacturing engineers, quality assurance and regulatory compliance teams, systems integrators and vendors of PLM/PDM/CAE software seeking neutral, machine-readable formats for material/test data exchange.

Typical applications and user profiles inferred from the AP intent and STEP family use cases.

Related standards

ISO 10303-235 is part of the larger ISO 10303 (STEP) family. Commonly referenced or related parts include fundamental and implementation resources such as ISO 10303-1 (overview and principles), ISO 10303-11 (EXPRESS), ISO 10303-21 (STEP-File), integrated resource parts (e.g., parts in the 400–499 range) and other application protocols such as AP203, AP214 and AP242 which address specific product-model exchange needs. Implementers will also reference ISO 13584 (parts libraries) when using controlled dictionaries for property and test-method names.

FAQ

Q: What is this standard?

A: ISO 10303-235:2019 is an application protocol (part of the ISO 10303 STEP family) that specifies how to represent and exchange engineering property data and material information for product design and validation.

Q: What does it cover?

A: It covers information models and integrated resources for describing products and specimens, material composition and substances, measurement and test processes, results with validity conditions, references to standards, qualifications of testers, measurement requirements/tolerances and approvals; it does not define the detailed names of properties/test methods or procedural test rules.

Q: Who typically uses it?

A: Product designers, materials engineers, test laboratories, QA/compliance teams, PLM/PDM/CAE/LIMS vendors and systems integrators who need a neutral, machine-interpretable representation of material and test/property data for exchange, validation and archival.

Q: Is it current or superseded?

A: ISO 10303-235:2019 is the second edition (published June 2019). The 2009 edition was withdrawn and replaced by the 2019 edition; the ISO record shows the 2019 edition was reviewed and confirmed in 2025, so the 2019 text remains the current published edition as of the ISO record review.

Q: Is it part of a series?

A: Yes — it is Part 235 of the ISO 10303 family (STEP). Implementers will typically use this AP together with the shared integrated resources, core parts of the ISO 10303 framework (EXPRESS, STEP-File, IR resources) and other APs as needed for complete product-data exchange solutions.

Q: What are the key keywords?

A: Engineering properties, material information, material composition, test data, measurement conditions, STEP, ISO 10303, application protocol, AIM, product data exchange.
