ISO 10303-235:2019

Overview

ISO 10303-235:2019 - part of the ISO 10303 (STEP) family - defines an application protocol for engineering properties and materials information. It specifies the information requirements, integrated resources and the Application Interpreted Model (AIM) needed to represent engineering property data used in product design, validation and related workflows. The standard supports neutral, computer-interpretable product data representation and exchange for measurement results, material composition, test conditions and approvals.

Key topics and technical requirements

• Scope of representation
  • Descriptions of the manufactured product, sampled specimen and testable sample version
  • Composition and substance information for materials
  • Test and measurement processes and the produced data values, together with the conditions of validity for those values
  • References to external standards and documents that specify sampling and measurement methods
  • Qualifications of personnel or organizations performing measurements
  • Measurement requirements, conditions, tolerances and the recorded outcomes
  • Measurement locations, effectivity/validity intervals and approvals that establish data validity
• Models and deliverables
  • Application Reference Model (ARM) describing information flows (Annex G / Annex F)
  • Application Interpreted Model (AIM) and AIM EXPRESS listings for implementation (Clause 5, Annex A/H)
  • Mapping specifications, conformance requirements and Protocol Implementation Conformance Statement (PICS) proforma
• Archiving & traceability
  • Support for archiving engineering-property data to meet legal, regulatory and quality objectives
• Explicit exclusions
  • Rules, guidelines or expert knowledge for testing; names of properties and test methods (assumed supplied via external dictionaries such as ISO 13584 Parts Libraries); decision rationale, scheduling data, and evaluation algorithms are out of scope

Practical applications

• Exchange of validated material and property data between CAD, CAE and PLM systems
• Recording test results, measurement conditions and approvals for design validation and structural integrity assessments
• Building interoperable materials databases and product test archives for regulatory compliance and quality assurance
• Enabling supplier-to-manufacturer data exchanges that include traceable measurement provenance and effectivity

Who uses ISO 10303-235

• Materials, mechanical and structural engineers capturing material properties for design and simulation
• Test laboratories and QA organizations that need machine-readable, provable measurement records
• PLM/CAD/CAE software vendors and system integrators implementing STEP/AP235 support
• Regulatory, compliance and records-management teams requiring long-term archiving of measurement data

Related standards and implementation notes

• Part of the ISO 10303 (STEP) suite for neutral product data exchange
• Names and definitions of properties/test methods are expected to come from ISO 13584 (Parts Libraries) or other computer-processable dictionaries
• Implementation artifacts include AIM EXPRESS schemas, conformance rules and PICS proformas provided in the standard
