ISO 15004-1:2020

Overview - ISO 15004-1:2020 (ophthalmic instruments)

ISO 15004-1:2020 defines fundamental requirements and type test methods for non-invasive ophthalmic instruments, including both active and non‑active devices and devices for enhancing low vision. It applies to tonometers but excludes ophthalmic instruments that contact the globe, operation microscopes, endoscopes and devices intended for laser investigation or laser treatment. Where IEC 60601‑1 is applicable, this part takes precedence for ophthalmic-specific requirements when differences exist.

Key topics and technical requirements

• Scope and definitions: Clarifies terms such as ophthalmic instrument, non‑invasive, active instrument, and manufacturer.
• Design and risk reduction: Devices must be designed to reduce risks consistent with state of the art; manufacturers are expected to follow risk management principles (see ISO 14971).
• Performance: Devices shall meet the performance claimed by the manufacturer under intended conditions of use.
• Materials and biocompatibility: Components contacting skin must not be toxic or cause significant allergic reactions; ISO 10993 is referenced for biocompatibility.
• Ignitability and flammability: Ignitability tests use glow‑wire methods per IEC 60695‑2‑11 (650 °C ± 10 °C) and IEC 60695‑2‑10 equipment.
• Thermal and mechanical hazards: Surface temperatures and mechanical safety limits reference IEC 60601‑1 allowable values and ergonomic design principles.
• Electrical safety for active devices: IEC 60601‑1 requirements apply; verification is via the electrical test sequence described in IEC 60601‑1 (Annex B) except where explicitly excluded.
• Optical radiation: Light hazard limits and protection requirements are addressed in ISO 15004‑2; this document defers to Part 2 for optical radiation safety.
• Information and marking: Manufacturer instructions must cover safe use, disinfection, environmental conditions, and required markings (manufacturer name, model, warnings, etc.).
• Test methods: All tests described are type tests (ignitability, surface temperature, electrical safety).

Applications and who uses this standard

• Medical device manufacturers designing and validating non‑invasive ophthalmic instruments (e.g., diagnostic optics, tonometers, low‑vision aids).
• Product development and regulatory teams preparing documentation for conformity assessment and market approval.
• Test laboratories performing type testing for safety (glow‑wire, thermal, electrical).
• Purchasing/procurement and clinical engineers verifying device specifications and labeling.
• Standards and quality managers aligning device design with international safety and information requirements.
