Full title and description

Industrial automation systems and integration — Product data representation and exchange — Part 62: Integrated generic resource: Equivalence validation of product data. This part of ISO 10303 (STEP) defines integrated generic resource constructs for representing equivalence validation criteria, associated inspection requirements and assessment specifications, and the representation of equivalence inspection results for product data (with detailed focus on annotated 3D model/shape data).

Abstract

Specifies structured representations to express criteria for equivalence, the inspection requirements to evaluate those criteria, the assessment specifications, and how to record detailed inspection results when comparing two sets of product data. The resource is intended for declaring, assuring and reporting equivalence of product data to enable guaranteed-equivalence use of exchanged product information — detailed treatment for annotated 3D model (shape) data is provided; equivalence algorithms themselves are out of scope.

Scope

Provides the integrated generic resource constructs needed to represent equivalence validation information for product data: high-level management elements, general equivalence criteria, criteria linked to inspection requirements and assessment specifications, and representation of equivalence validation results. The resource covers annotated 3D model (shape) data in detail (target shape models are expected to conform to ISO 10303-42 or APs based on it). It does not specify equivalence-validation algorithms or processes for improving equivalence.

Key topics and requirements

• Data constructs for declaring and managing equivalence validation requirements and declarations.
• Representation of general equivalence validation criteria and thresholds used to assess whether two product data sets can be treated as equivalent.
• Linking of criteria to inspection requirements and assessment specifications to enable reproducible equivalence checks.
• Structured representation of detailed inspection results, including annotated 3D model equivalence findings.
• Explicit exclusions: algorithms for performing equivalence checks and process models to improve equivalence are outside the resource scope.

Typical use and users

Used by implementers of STEP data exchange (tool vendors, CAD/PDM/PLM integrators), quality and validation engineers, and organizations that need to declare or verify equivalence of product data between different systems or representations (for example, after translation, simplification, or during long-term archival retrieval). It supports automated and human-reviewed equivalence inspection workflows by providing a consistent representation for criteria, inspection requirements and detailed results.

Related standards

Part of the ISO 10303 (STEP) family. Closely related documents and resources include ISO 10303-42 (geometric and topological representation), ISO 10303-41 (fundamentals of product description and support), ISO 10303-59 (product data quality / PDQ-S), and other IR/AP modules that provide shape, PMI and assembly semantics used when performing equivalence validations. The SMRL entries and application-module discussions provide the mapping between this IR and specific APs.

FAQ

Q: What is this standard?

A: It is ISO 10303-62, an integrated generic resource within the ISO 10303 (STEP) family that defines data constructs for representing equivalence validation of product data. Edition 1 was published in October 2018.

Q: What does it cover?

A: It covers representation of equivalence validation criteria, associated inspection requirements and assessment specifications, and the structured recording of equivalence inspection results (with detailed focus on annotated 3D model/shape data). It does not define the algorithms used to perform the equivalence checks.

Q: Who typically uses it?

A: CAD/PLM/PDM tool vendors, systems integrators, quality engineers, validation teams and organizations exchanging or archiving product data that must be proven equivalent across representations or systems.

Q: Is it current or superseded?

A: The 2018 edition is withdrawn; it has been superseded by a revised edition published in 2025 (ISO 10303-62:2025, Edition 2). Users should prefer the 2025 edition for current implementations.

Q: Is it part of a series?

A: Yes — it is Part 62 of ISO 10303 (STEP). ISO 10303 is a large multi-part standard covering vocabulary, description methods, integrated resources (IR), application protocols (AP) and related modules; Part 62 is one of the Integrated Generic Resources (IR).

Q: What are the key keywords?

A: Equivalence validation, inspection requirement, assessment specification, annotated 3D model, STEP, ISO 10303, product data equivalence, product data quality.
