Overview
ISO/TR 10303-307:2000 is an Abstract Test Suite (ATS) in the ISO 10303 family for product data representation and exchange focused on sheet metal die planning and design. The report defines a structured set of test purposes and abstract test cases derived from the information requirements and the AIM (Application Interpreted Model) EXPRESS schema referenced in ISO 10303-207. It is intended to support conformance testing of implementations that exchange die- and sheet‑metal-related product data.
Key topics and technical requirements
- Abstract Test Suite (ATS) structure: Defines test purposes, abstract test cases (ATC), input specifications, verdict criteria, and roles such as implementation under test (IUT), preprocessor, and postprocessor.
- Test purpose derivation: Test purposes are derived from AP information requirements and the AIM EXPRESS schema; they include application element (AE) test purposes that ensure semantic preservation of elements between input and output.
- Application elements (AEs): Extensive AE listings cover entities relevant to die planning and sheet metal design, e.g. Die, Die_definition, Die_shape_definition, Feature, Feature_property, Final_part_definition, Dimensional_representation, Shape_tolerance, Process_operation and many dimension/tolerance types (angle, distance, diameter, curve length).
- Conformance criteria: The ATS defines what it means for an IUT to “preserve the semantics” of AEs, including mapping paths specified in the AP and associated verdict criteria for pass/fail.
- Supporting terminology and models: Includes AIM, ARM, AP concepts and abbreviations such as ATC, ATS, AE, AIM, AP, IUT, and references to modeling styles (B‑rep, CSG) and SI units.
Applications and practical value
- Validate interoperability of CAD/CAM and tooling systems that exchange sheet metal die and tooling data.
- Test preprocessors and postprocessors that convert between internal representations and STEP-compliant exchange files.
- Provide QA teams and integrators with objective, repeatable tests to verify semantic consistency (not just geometry) across systems.
- Reduce integration risk for manufacturing workflows involving die planning, tooling design, process planning, and stamping press operations.
Who should use this standard
- CAD/CAM and PLM software vendors implementing STEP/AP mappings for sheet metal and die design.
- System integrators and quality assurance teams performing conformance and interoperability testing.
- Tooling designers, stamping and die engineers who need robust data exchange between design and manufacturing systems.
- Standards bodies and test laboratories defining or running automated conformance suites.
