Full title and description

ISO 10303-45:2008 — Industrial automation systems and integration — Product data representation and exchange — Part 45: Integrated generic resource: Material and other engineering properties. This part of ISO 10303 (STEP) defines the integrated generic resources used to describe material composition and material-related engineering properties of products, the conditions under which those property values are valid, and qualifiers such as precision and uncertainty. The 2008 publication is Edition 2 of Part 45 and is provided here as the PDF edition reference.

Abstract

ISO 10303-45:2008 specifies data constructs (integrated generic resources) for representing values of material and other engineering properties of products and the conditions in which those values are valid. It also provides constructs for describing product composition. Property and composition values may be expressed as numeric values or as mathematical functions and may be qualified by type, precision, uncertainty and applicable conditions.

Scope

This part of ISO 10303 provides integrated generic resource constructs to: specify the set of qualitative and quantitative conditions under which a material or engineering property is valid; represent material and property values (including numeric values and mathematical expressions); describe the composition of products (alloys, compounds, composites); and qualify values with measures of uncertainty, qualifiers (e.g., minimum/maximum), and reliability. The standard is intended for representation and exchange of material-related data across CAD, CAE, manufacturing and product lifecycle systems, while relying on other ISO resources and dictionaries for specific property names and test methods.

Key topics and requirements

• Definitions of material property types and entities for consistent representation of properties (mechanical, thermal, electrical, chemical, etc.).
• Representation of property values as numeric values or mathematical functions (to allow temperature- or frequency-dependent properties).
• Specification of measurement/assignment conditions and qualifiers that define the validity context for a property value (e.g., temperature, pressure, microstructure state).
• Mechanisms to express precision, statistical uncertainty and qualifiers (minimum, maximum, standardized values) for measured or assigned values.
• Entities and constructs to describe product composition (constituents, fractions, alloys, composites) and to associate composition with material designations.
• Integration with other ISO 10303 integrated resources and with external dictionaries (e.g., ISO 13584 parts libraries) for property names and testing standards.

Typical use and users

Used by CAD/CAM/CAE/PLM implementers, materials engineers, product designers, manufacturing engineers, data exchange and integration specialists, and organizations managing material data libraries or long‑term product archives. Typical use cases include exchanging validated material property data between simulation and design tools, encoding product material composition for compliance or supplier communication, and populating PLM systems with qualified property values for downstream engineering and manufacturing.

Related standards

ISO 10303 is a multi-part family (STEP). Related parts and standards commonly used with Part 45 include ISO 10303-41 (integrated generic resources), ISO 10303-11 (EXPRESS language), ISO 10303-21 (STEP-file), application protocols such as AP203 / AP214 / AP242 for product data exchange, and ISO 13584 (Parts library / PLIB) for property and test method dictionaries. Note: Part 45 has later revisions and editions (examples: ISO 10303-45:2014 and ISO 10303-45:2019) that update and refine the resources defined in the 2008 edition.

FAQ

Q: What is this standard?

A: ISO 10303-45:2008 is Part 45 of the ISO 10303 family (STEP) that defines integrated generic data resources for representing material and other engineering properties and product composition in a machine‑readable, exchangeable form.

Q: What does it cover?

A: It covers data constructs for material property definitions and representations, composition descriptions, qualifiers and measures of uncertainty, and the conditions under which property values are valid. It does not define specific property names or test methods (those are provided by dictionaries or application protocols).

Q: Who typically uses it?

A: Materials engineers, CAD/CAE/PLM software developers, integrators exchanging material data between systems, data archivists, and standards or compliance teams that need a canonical representation of material properties and composition for product data exchange.

Q: Is it current or superseded?

A: The 2008 edition is withdrawn. Part 45 has later revisions; ISO published subsequent editions (including publications in 2014 and a confirmed edition published in November 2019). For current implementations and authoritative text, consult the most recent published edition of ISO 10303-45.

Q: Is it part of a series?

A: Yes. It is part of the ISO 10303 (STEP) family of standards for product data representation and exchange; Part 45 is the integrated generic resource for material and other engineering properties and is intended to be used in combination with other parts (integrated resources, application protocols, EXPRESS definitions, etc.).

Q: What are the key keywords?

A: material properties, engineering properties, composition, STEP, ISO 10303, property representation, uncertainty, qualifiers, PLM, EXPRESS.
