Full title and description

Industrial automation systems and integration — Product data representation and exchange — Part 1074: Application module: Property condition. This Technical Specification defines the STEP application module that captures property-condition constructs used to express necessary property conditions for membership of product or activity classes.

Abstract

ISO/TS 10303-1074:2005 specifies an application module called "Property condition" for the ISO 10303 (STEP) family. It covers the data constructs required to express necessary property conditions for membership in a class of product and for membership in a class of activity.

Scope

This Technical Specification defines the semantics and data constructs of an application module that represents property conditions used in STEP-based product data exchange. It is intended to be used as a modular building block in EXPRESS-based application protocols to allow consistent representation of necessary property-based membership constraints for product classes and activity classes.

Key topics and requirements

• Definition of the "Property condition" application module for STEP (EXPRESS data constructs and relationships).
• Representation of necessary property conditions for class membership (product classes and activity classes).
• Data types and entity definitions required for expressing property qualifiers and condition constraints.
• Integration guidance for including the module within larger ISO 10303 application protocols and libraries.
• Conformance expectations for implementations that reuse the module in STEP/AP contexts.

Typical use and users

Implementers of STEP-based data exchange (AP developers), PLM and CAD/PDM system vendors, system integrators, and standards working groups use this module when they need a standard, reusable way to express property-based membership constraints. Typical scenarios include class-definition libraries, automated classification and validation rules, and data exchange between enterprise systems that require explicit property-condition semantics.

Related standards

ISO/TS 10303-1074:2005 is part of the ISO 10303 (STEP) family. Related parts include other application modules and APs in the 10xx–12xx range (for example nearby application-module parts and class/activity related modules) and higher-level APs such as AP214/AP242 where property and classification information may be used. The ISO 10303 series contains many companion parts and application modules that are commonly used together.

FAQ

Q: What is this standard?

A: It is ISO/TS 10303-1074:2005, a Technical Specification in the ISO 10303 (STEP) family that defines the "Property condition" application module used to express necessary property conditions for class membership.

Q: What does it cover?

A: It covers the data-model constructs, entity definitions and semantics needed to represent necessary property conditions for membership in product and activity classes, intended for reuse in STEP application protocols and libraries.

Q: Who typically uses it?

A: AP developers, PLM/CAD/PDM software vendors, systems integrators, and standards committees use this module when they need a standardized representation of property-based classification and membership constraints in STEP data exchanges.

Q: Is it current or superseded?

A: The Technical Specification was published in December 2005 (Edition 1) and, according to ISO records, it has been subject to systematic review and was confirmed as current in ISO's review cycle (most recently confirmed in 2023).
