IEC 62368-1

Edition, correction notice and catalogue records checked on 7 October 2026. Verify the required publication and regional additions before ordering.

What does IEC 62368-1 address?

The standard takes an energy-source and safeguard approach to product safety. IEC lists Edition 4.0, published on 26 May 2023, and labels the present record “corrected version 2025-08”. See the IEC publisher record. BSI's European publication overview identifies examples including computers, networking equipment, displays and audio/video products.

For procurement, turn the product name into an assessment brief: power sources, connected accessories, available interfaces, installation conditions and who can access the equipment. Then ask the laboratory to confirm applicability. “It contains electronics” is not a sufficient basis for choosing this standard.

Check scope and exclusions before purchasing

The publicly available IEC preview describes AV/ICT and business or office equipment with rated voltage not exceeding 600 V. It also identifies boundaries: performance characteristics are outside its scope, as are personal care robots, equipment with non-self-contained hazardous moving parts and equipment intended for wet indoor areas. These examples are not a complete list of exclusions.

If your product combines several functions, explain the whole intended use to the assessor. A display in a machine, a communications module in medical equipment and a stand-alone office monitor are different assessment questions. Clarify the product category before treating a familiar electronics standard as the complete answer.

IEC 2023 or EN IEC 2024?

Genorma has separate records for EN IEC 62368-1:2024 and A11:2024. Their different year from the IEC document is a reason to check the full reference, not an indication that the document you need can be selected by year alone.

For an EU project, verify the applicable legislation and current Official Journal citation independently. The Commission's harmonised-standards explanation describes their legal role. This guide does not assert that the 2024 European edition is currently cited or resolves every market-entry obligation.

What does the correction notice mean for your order?

Both the Genorma record and IEC's catalogue flag an August 2025 corrected version. Keep the edition year, edition number and correction information together in your purchasing record. “2023 Edition 4” alone is less useful when checking which file an engineer actually used.

For an existing project, ask the document owner to compare its stored copy with the publisher's correction notice and agree the implications with the assessor. Do not assume the notice proves that a past report is invalid, or that it can be ignored. Record the review outcome and update controlled references where appropriate.

Understand the roles of Parts 2 and 3

IEC TR 62368-2:2025 provides explanatory material relating to IEC 62368-1:2023. Consider it when the team needs background to interpret the main document; a technical report is a different purchase from the Part 1 safety standard.

For equipment transferring DC power through communication cables such as USB or Ethernet, the IEC preview points to additional requirements in IEC 62368-3. Tell the laboratory how each interface supplies or receives power, including the protocol and connected equipment. Confirm the relevant Part 3 reference rather than adding it to every electronics order automatically.

Example: buying documents for a powered docking station

A distributor plans to sell a laptop docking station with an external power supply, USB connections and an Ethernet port. Its supplier provides an older test report and describes the product as “62368 compliant”. The distributor's purchasing team first asks for the report's exact standard designation, tested model, power supply and hardware version.

The laboratory receives the complete product description and confirms whether the proposed assessment uses IEC 62368-1:2023 or an EN publication with regional additions. It also checks whether the power-transfer arrangement calls for Part 3. The buyer orders that agreed set, verifies the correction notice and keeps the document references beside the assessment quotation. The supplier's broad statement becomes a specific evidence request rather than the basis for an unexamined document order.

A practical purchase checklist

1. Describe the finished equipment. Include power supplies, accessories, ports and intended users.
2. Confirm the assessment reference. Obtain the complete IEC, EN or national designation, including amendments.
3. Resolve corrections and supporting parts. Check the supplied file and any separately required explanatory or power-transfer document.
4. Choose the licence. Check access for the people preparing the design review, test plan and technical documentation.
5. Keep model and edition traceable. Record which hardware configuration and assessment each purchase supports.

Frequently asked questions

Can I use the IEC document when the laboratory asks for EN IEC 62368-1?

Ask the laboratory to confirm the needed European text and amendments. Do not substitute the international publication simply because the main number matches.

Is the corrected version a fifth edition?

No. IEC's public record still identifies Edition 4.0 under the 2023 designation and separately flags the August 2025 correction.

Does this cover functional safety of a control system?

The Part 2 explanatory record distinguishes functional safety and points to IEC 61508-1. If equipment controls a safety function, scope that assessment separately with the responsible engineer.

Should I buy Part 2 instead of Part 1?

Choose Part 1 when you need the safety standard itself. Evaluate the explanatory technical report as supporting material for your team; ask the assessor what the assignment requires.
