As the healthcare industry accelerates toward AI‑integrated care, one truth has become impossible to ignore: the safety, reliability and accountability of AI systems depend entirely on the quality of the data used to build them. And until now, the medical device sector has lacked a unified, lifecycle‑driven framework for managing that data.
PD IEC PAS 63621:2026 changes that.
Developed by IEC Technical Committee 62 with input from relevant stakeholders, this new Publicly Available Specification (PAS) offers a high‑level framework for data management in AI‑enabled medical devices. It supports safer, more trustworthy AI at a time when global health systems need it most.
In this article, we explore the significance of the PAS, its role in the rapidly evolving AI landscape and why organizations across the medical device ecosystem should be paying attention.
AI has rapidly shifted from experimental technology to everyday medical infrastructure.
Hospitals now rely on AI to ease radiology backlogs, streamline pathology workflows, improve bed management and tailor treatment decisions. From wearables to image‑guided surgical systems, machine learning is becoming integral to medical device innovation.
But as adoption accelerates, a new regulatory and ethical challenge has emerged: AI is only as dependable as the data behind it. Inadequate or poorly controlled datasets can introduce bias, cause performance drift, compromise safety, obscure clinical evidence and ultimately lead to regulatory non‑compliance.
Global regulators are increasingly demanding rigorous, auditable, lifecycle‑based controls for AI‑related data. Yet until recently, the medical device industry lacked a unified reference for managing such data. Manufacturers created their own processes, external data providers followed different standards and clinical partners operated with limited guidance, resulting in fragmented, inconsistent and often non‑aligned practices.
PD IEC PAS 63621:2026 delivers an internationally aligned framework that supports data management into medical device quality systems.
At its heart, the PAS provides a structured blueprint for managing data across every stage of the AI lifecycle, from initial planning to end‑of‑life decommissioning. It is intentionally high‑level structured, ensuring it applies across all device types, medical specialties and AI architectures.
The PAS recognizes that organizations may be involved in any combination of activities - design and development, production, implementation, servicing, external data supply - and defines requirements flexible enough to fit each scenario.
Its core goals include:
Ensuring data used in AI devices is safe, reliable and fit for purpose.
Providing structured processes for dataset creation, validation and ongoing quality improvement.
Creating common expectations for manufacturers, suppliers, clinical data providers and auditors.
Embedding data management supporting integration with a BS EN ISO 13485 quality management system.
Strengthening links between data quality and risk management, particularly for safety‑critical AI.
Supporting regulatory readiness and reducing ambiguity in data generation.
By offering a complete end‑to‑end lifecycle model, the PAS positions data management not as a technical afterthought, but as a central pillar of product safety.
PD IEC PAS 63621:2026 takes a holistic view of data management for AI‑enabled medical devices, outlining the key stages organizations typically consider when handling data throughout its lifecycle. Rather than prescribing detailed requirements, it provides a structured, high‑level framework that helps align data‑related activities with good practice in the medical‑device context.
The PAS highlights themes such as:
1. Establishing a structured approach to data planning
It encourages organizations to think proactively about the types of data they work with, how that data relates to the intended purpose of the AI system and how it will be documented and managed over time.
2. Considering how data is sourced and selected
The framework reinforces the importance of approaching data acquisition thoughtfully, taking into account factors like suitability, diversity, privacy and the broader context in which data originates.
3. Supporting robust data development and annotation practices
It touches on the need for clarity and consistency in how data is described, labelled, organized and updated. This includes maintaining transparency about data origins, characteristics, and any transformations applied.
4. Maintaining an ongoing view of data quality
The PAS promotes a lifecycle perspective in which data quality is monitored over time, reflecting factors such as accuracy, relevance, completeness and how those aspects may evolve.
5. Encouraging evaluation and awareness of potential bias
It recognizes the importance of examining datasets for issues that could impact fairness, safety, or performance and of fostering practices that support more reliable and equitable AI outcomes.
6. Managing how data is shared, accessed and stored
Topics such as secure handling, appropriate access, traceability and clear governance structures are highlighted as important to the overall integrity of data processes.
7. Taking a lifecycle view of monitoring and eventual retirement
The framework acknowledges that data changes over time and may need to be reviewed, updated, or responsibly decommissioned as technologies, clinical realities, or organizational needs evolve.
8. Supporting data‑related activities with wider quality management practices
It places data management in the context of established medical‑device quality systems, supporting consistency, traceability and organizational capability.
Taken together, these themes form a cohesive, high‑level reference that helps organizations bring structure, clarity and accountability to the way they manage data for AI‑enabled medical devices, without dictating specific methods or technical solutions.
Above all, PD IEC PAS 63621 contributes to safer, more predictable AI in clinical environments.
It ensures organizations establish rigorous controls around the data that drives model performance - controls that reduce bias, support fairness, strengthen safety and build trustworthy data.
As AI becomes increasingly integrated into patient care, this level of structure and transparency is essential. The PAS sets the foundation the sector needs today and positions organizations to meet the regulatory and ethical expectations of tomorrow.
