Full title and description

Industrial automation systems and integration — Product data representation and exchange — Part 34: Conformance testing methodology and framework: Abstract test methods for application protocol implementations. This part of ISO 10303 (STEP) defines abstract test methods and an overall conformance-testing framework for implementations of ISO 10303 Application Protocols (APs), addressing both exchange‑structure (STEP-file) and SDAI-based implementation styles.

Abstract

ISO 10303-34:2001 specifies abstract test methods for conformance assessment of preprocessors (that generate STEP schema instances) and postprocessors (that accept/interpret STEP schema instances). It describes the conformance assessment process, test preparation, test execution (syntax, structure and semantic analyses), verdict assignment and test reporting; it is implementation‑method independent and applies to exchange structure (ISO 10303-21) and SDAI (ISO 10303-22) environments. The standard does not cover generation of executable test cases from abstract test cases nor AP‑independent SDAI implementations.

General information

• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 25.040.40 (Industrial process measurement and control).
• Edition / version: First edition (2001).
• Number of pages: 15 pages (typical ISO publication length for this part).

Scope

This part of ISO 10303 defines abstract test methods for conformance testing of implementations of ISO 10303 Application Protocols. The scope covers preprocessors that generate schema instances as exchange structures (ISO 10303-21), postprocessors that accept/interpret such exchange structures, and implementations that use the SDAI interface (ISO 10303-22) to populate or extract schema instances. Within scope are the conformance assessment process, the abstract test method descriptions (from ATC selection to test reporting) and methods for testing laboratories using executable test cases; outside the scope is the automatic generation of executable test cases from abstract test cases and AP‑independent SDAI conformance methods.

Key topics and requirements

• Definition of two abstract test methods: one for preprocessors (exchange structure generation) and one for postprocessors (exchange structure interpretation).
• Test analyses divided into syntax analysis, structure analysis (AIM/schema conformance) and semantic analysis (information preservation).
• Conformance assessment lifecycle: preparation, test campaign execution, result analysis, verdict assignment (pass/fail/inconclusive) and report production.
• Roles and components: Implementation Under Test (IUT), Test Engine, testing laboratory and SUT operator definitions.
• Use of PICS/PIXIT for documenting implementation claims and test prerequisites; requirements for conformance logs and test case reports.
• Explicit exclusions: does not specify how to generate executable test cases (ETCs) from abstract test cases, and does not include AP‑independent SDAI conformance testing methods.

Typical use and users

Primary users are testing and certification laboratories, software vendors of CAD/PLM/CAE tools (implementing STEP export/import or SDAI interfaces), system integrators, QA teams and tool developers creating test engines/harnesses. Typical uses include validating STEP file exporters/importers, verifying SDAI‑based data sharing, and producing accredited conformance reports to demonstrate AP compliance.

Related standards

ISO 10303-34 is part of the STEP family (ISO 10303). Closely related parts include ISO 10303-1 (overview and fundamental principles), ISO 10303-11 (EXPRESS language), ISO 10303-21 (exchange structure / STEP-file), ISO 10303-22 (SDAI), ISO 10303-31 (general conformance framework) and ISO 10303-32 (requirements on testing laboratories); other STEP resources (e.g., parts for product representation and APs) are also relevant when preparing or executing conformance tests.

FAQ

Q: What is this standard?

A: ISO 10303-34:2001 is the STEP (ISO 10303) part that defines abstract test methods and a framework for conformance testing of application‑protocol implementations (preprocessors and postprocessors, including SDAI‑based implementations).

Q: What does it cover?

A: It covers the conformance assessment process, abstract test method descriptions (selection of abstract test cases, execution principles, analyses and verdicts), reporting requirements and methods for testing laboratories using executable test cases; it applies to implementations using exchange structures (ISO 10303‑21) and SDAI (ISO 10303‑22). It does not define how to generate executable test cases from abstract test cases.

Q: Who typically uses it?

A: Testing/certification laboratories, CAD/PLM/CAE vendors (exporter/importer developers), system integrators, QA teams and developers of test tools and test engines.

Q: Is it current or superseded?

A: ISO 10303-34 was published as the first edition in 2001 and has been maintained in ISO’s program; catalog entries show it as the 2001 first edition and recent ISO maintenance listings include reconfirmation actions of many STEP parts. Users should check the ISO catalogue for the absolute latest status before purchase or certification activities.

Q: Is it part of a series?

A: Yes — it is one part of the ISO 10303 (STEP) series, which is a large family of standards for product data representation and exchange; related parts define EXPRESS, exchange formats, SDAI, conformance frameworks and many application protocols.

Q: What are the key keywords?

A: STEP, conformance testing, abstract test methods, exchange structure (ISO 10303-21), SDAI (ISO 10303-22), application protocol (AP), ATC/ATS, ETC, PICS, PIXIT.
