Full title and description

VDI 5707 Blatt 1:2023-02 — Wiederholungsprüfungen an aktiven Medizinprodukten im medizinischen Einsatz — Prüfgrundlagen. (English title: Retesting of active medical devices in medical use — Testing principles). This VDI technical rule gives foundational recommendations and principles for planning and carrying out recurrent (periodic) testing and maintenance of active medical devices used in clinical settings, with an emphasis on evidence-based, risk-informed strategies that ensure patient and user safety while optimising resources.

Abstract

This guideline defines testing principles for the recurrent (retesting) inspection and maintenance of active medical devices in medical use. It presents evidence‑based approaches to determine inspection intervals and test scopes, explains roles and responsibilities for operators and service providers, and describes documentation, risk assessment and decision criteria to balance safety, effectiveness and cost-efficiency. The guideline is intended to harmonise local maintenance practice with applicable safety requirements and to support the integration of real usage data into maintenance strategies.

Scope

VDI 5707 Blatt 1 provides the basic principles for planning and performing recurrent tests (Wiederholungsprüfungen) of active medical devices that are in clinical use. The scope covers general testing objectives, risk-based selection of test items and intervals, evidence‑based maintenance strategies, minimum documentation and reporting requirements, and roles/responsibilities of device operators, clinical engineering/biomedical service teams and external maintenance providers. The guideline is not a product-specific test protocol but a framework to derive device‑ or group‑specific procedures.

Key topics and requirements

• Principles of evidence‑based maintenance and retesting for active medical devices.
• Risk-based determination of test content and retest intervals (including use-history and failure data).
• Fundamental test objectives: patient and user safety, functional verification and detection of wear/aging.
• Minimum documentation and traceability requirements for retesting and maintenance actions.
• Roles and responsibilities: operators, clinical engineering/biomedical staff, service organisations and manufacturers.
• Guidance on selection of test methods and acceptance criteria, and when to follow manufacturer instructions or adapt them using local evidence.
• Recommendations for integrating usage data and clinical context into maintenance planning.
• Alignment with existing safety standards and regulatory expectations for medical electrical equipment.

Typical use and users

This guideline is used by hospital clinical engineering and biomedical equipment management teams, medical device service organisations, medical device manufacturers (for maintenance guidance), quality and risk managers in healthcare facilities, and regulatory or accreditation bodies seeking consistent, evidence‑based approaches to recurrent testing. It is intended for professionals responsible for maintaining the safety and availability of active medical devices in clinical environments.

Related standards

Relevant standards and guidance that are often considered together with VDI 5707 Blatt 1 include IEC 62353 (Recurrent test and test after repair of medical electrical equipment), the IEC/EN 60601 series (medical electrical equipment safety requirements), ISO 13485 (medical device quality management), and national test standards for electrical safety. VDI is developing additional parts in the VDI 5707 series (device-group-specific procedures and practical implementations) to complement Blatt 1.

FAQ

Q: What is this standard?

A: VDI 5707 Blatt 1:2023-02 is a VDI technical rule that sets out the testing principles and foundational recommendations for recurrent testing and maintenance of active medical devices used in clinical settings.

Q: What does it cover?

A: It covers principles for evidence‑based recurrent testing, risk‑based selection of tests and intervals, documentation and roles/responsibilities for operators and service providers. It provides a framework for deriving device‑specific retest procedures rather than prescribing single prescriptive test protocols for every device type.

Q: Who typically uses it?

A: Clinical engineering/biomedical teams in hospitals, maintenance and service organisations for medical devices, device manufacturers advising on maintenance, and quality/risk managers in healthcare facilities.

Q: Is it current or superseded?

A: The document is current as published on 1 February 2023 (edition 2023-02). It supersedes earlier draft versions; users should confirm they are using the 2023-02 edition when applying the guideline.

Q: Is it part of a series?

A: Yes — VDI 5707 Blatt 1 is the first part of a VDI guideline series on recurrent testing of active medical devices. Further parts (device-group-specific procedures and practical guidance) have been planned or are under development to expand the framework into device-specific recommendations.

Q: What are the key keywords?

A: Retesting, recurrent testing, active medical devices, evidence-based maintenance, clinical engineering, periodic inspection, VDI 5707, safety, risk-based maintenance.
