Overview - ISO/IEC 8803:2025 in brief
ISO/IEC 8803:2025 establishes a standardized accuracy and precision evaluation process specifically for modelling from 3D scanned data. It provides a common framework of processes, activities and tasks to evaluate quality factors (accuracy, precision, reproducibility) in the pipeline from 3D scanning to digital model creation. Importantly, this standard focuses on the modelling stage and does not evaluate the final 3D printed product.
Key technical topics and requirements
- Evaluation model and reference processes: defines an evaluation model tailored to 3D scanning and modelling workflows, including stakeholder roles (provider, producer, customer, partner, policymaker).
- Structured evaluation process (Clause 5): stepwise requirements to
- establish evaluation requirements (purpose, product quality requirements, tasks/phases included, evaluation stringency),
- specify the evaluation (select quality measures/evaluation modules, define decision criteria),
- design the evaluation (plan activities and measurements),
- execute the evaluation (perform measurements and apply decision rules),
- conclude and report (review results, create evaluation reports, manage evaluation data).
- Support materials and templates: informative annexes include task/phase descriptions, an evaluation report template, and a comparison with SQuaRE (ISO/IEC 25040 family).
- Quality dimensions: covers accuracy, precision and reproducibility in the context of errors introduced through scanning, segmentation, modelling and post-processing.
Practical applications
- Establishing repeatable quality assurance for scan-to-model pipelines in industries using digital twins, reverse engineering, heritage capture, and medical imaging.
- Benchmarking and validating 3D scanners and modelling workflows: helping organizations compare technologies (optical, LiDAR, CT) and document limitations (e.g., reflective or transparent surfaces).
- Defining acceptance criteria and decision thresholds for procurement, supplier evaluation and compliance activities involving digital 3D models.
- Supporting R&D and process-improvement projects that target error minimization and reproducibility across imaging, segmentation and modelling steps.
Who should use this standard
- 3D scanning and modelling service providers
- Manufacturers and producers of 3D models and related software
- Quality, metrology and R&D teams validating scan-to-model workflows
- Procurement officers and policymakers setting conformance expectations
- Researchers and integrators working on 3D printing workflows where the fidelity of source models is critical
Related standards
- ISO/IEC 25040 and ISO/IEC 25041 (SQuaRE series) - referenced as normative materials for quality evaluation frameworks and alignment with systems/software quality evaluation practices.
