Full title and description

Industrial automation systems and integration — Product data representation and exchange — Part 59: Integrated generic resource: Quality of product shape data. This part of ISO 10303 (STEP) defines integrated generic resource constructs to represent, declare and exchange information about the quality of product shape data, including criteria, measurement requirements, assessment specifications and inspection results for three‑dimensional and annotated 3D model data.

Abstract

This document provides structured representations for product data quality focused primarily on 3D shape data and annotated 3D model data. It specifies high‑level elements for managing quality information, general quality criteria, associated measurement requirements and assessment specifications, and ways to record inspection results. The standard is intended to enable quality declarations, quality assurance and the exchange of quality inspection results between systems while leaving specific measurement algorithms to implementers.

General information

• Status: Withdrawn (stage: Withdrawal of International Standard).
• Publication date: September 2021 (corrected version December 2021).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 25.040.40 (Industrial process measurement and control / product data representation and exchange).
• Edition / version: Edition 3 (2021).
• Number of pages: 1 290 pages (official PDF/page count reported by the ISO entry).

Scope

The standard defines schemas and constructs to represent quality information for product data with emphasis on three‑dimensional shape data and annotated 3D models. In scope are: representation of high‑level quality management elements; general quality criteria; measurement requirements tied to criteria; assessment specifications; and representation of inspection results for both shape data and annotated 3D model data. The document explicitly excludes specification of measurement algorithms, tolerance‑to‑shape quality relationships, and detailed aesthetic quality evaluation methods.

Key topics and requirements

• Data models for quality information: schemas for product_data_quality_definition, product_data_quality_criteria and product_data_quality_inspection_result.
• Definition and classification of quality criteria for geometry, topology and combined geometry/topology issues.
• Association of each quality criterion with a measurement requirement and optional assessment specification (textual description of how to evaluate).
• Representation of inspection results and declared quality levels for exchanged product data.
• Support for annotated 3D model quality (including PMI and tessellated/scan data) and extensibility for other product data types in future editions.
• Separation of standardized data representation from specific numerical algorithms — implementers provide measurement procedures.

Typical use and users

Used by CAD/CAM/PLM vendors, manufacturing companies, QA and inspection teams, data exchange integrators and software developers who need to declare, verify or exchange the quality of 3D product data. Typical applications include supplier data acceptance, archival of model quality metadata, interoperability between engineering systems, and automated pre‑processing checks in the digital thread.

Related standards

Part of the ISO 10303 (STEP) family. Related items include ISO 10303‑42 (geometric and topological representation), various application protocols and AP/TS specializations (for example ISO/TS 10303‑1821 and 1822 for externally conditioned data quality specializations) and other STEP parts used for model‑based 3D engineering such as ISO 10303‑242 (managed model‑based 3D engineering). Historical editions (e.g., 2014) and subsequent revisions (noted revisions after 2021) are relevant for implementers tracking lifecycle changes.

FAQ

Q: What is this standard?

A: ISO 10303‑59:2021 is a part of the STEP family that defines data constructs for representing the quality of product shape data and annotated 3D model quality – including criteria, measurement requirements and inspection results – to support quality declaration and interoperable exchange.

Q: What does it cover?

A: It covers high‑level data elements and schemas to express quality criteria for geometry and topology, associated measurement requirements and assessment specifications, and how to record inspection results for three‑dimensional and annotated 3D model data. It does not standardize specific measurement algorithms.

Q: Who typically uses it?

A: CAD/PLM/CAE software vendors, manufacturing engineering and quality assurance teams, system integrators and organizations engaged in digital data exchange and model‑based definition workflows.

Q: Is it current or superseded?

A: The ISO record for the 2021 edition indicates a lifecycle stage of withdrawal; implementers should check the ISO catalogue or national bodies for the latest status and any successor edition (ISO records note corrections in December 2021 and lifecycle updates). Because national catalogues and distributors can show different availability statuses, verify with the ISO entry or your national standards body for purchase and current applicability.

Q: Is it part of a series?

A: Yes — it is Part 59 of ISO 10303 (the STEP series) and is intended to work with other STEP parts such as ISO 10303‑42 and application protocols like ISO 10303‑242 and TS specializations for externally conditioned quality data.

Q: What are the key keywords?

A: Product data quality, shape data quality, quality criteria, measurement requirement, inspection result, annotated 3D model, STEP, ISO 10303.
