Machinery Regulation Harmonised Standards List 2026 — Which EN ISO/IEC Standards Give Presumption of Conformity

A useful first check is the legislation named in a decision, not the words “safety devices” in its title. Decision (EU) 2026/79 concerns pressure equipment. It illustrates why a technical file needs the exact legal reference, rather than a plausible-looking number copied from a standards headline.

Does Implementing Decision (EU) 2026/79 list machinery standards?

No. This is the misreading worth killing first. Commission Implementing Decision (EU) 2026/79 of 12 January 2026, published in the Official Journal on 13 January 2026 and in force from that day, has nothing to do with the Machinery Regulation. Its full title amends Implementing Decision (EU) 2025/165 as regards harmonised standards drafted in support of Directive 2014/68/EU — the Pressure Equipment Directive.

The standards it adds or updates are pressure-equipment standards: EN 10216-2:2024 for seamless steel tubes, EN 10253-4:2025 for butt-welding pipe fittings, the EN 12420 / EN 12735-2 / EN 1982:2024 copper and copper-alloy set, EN 13445-5:2021+A1:2024 for unfired pressure vessels, EN 1591-1:2024 for flanges and their joints, EN 16668:2025 for industrial valves, and EN ISO 4126-10:2024 for safety devices against excessive pressure. Not one of those touches a light curtain, a laser scanner or a safety relay. The word “safety devices” in its title means pressure-relief valves and bursting discs, not machine-guarding sensors. If you have seen 2026/79 quoted as a Machinery Regulation list — and it has been, in a few places — treat that as wrong and move on.

Are any standards cited under the Machinery Regulation yet?

Treat this as a dated tracking exercise. On the Commission machinery standards index checked for this article, the published list and amendments are identified under Directive 2006/42/EC. This supports using that index to locate the Directive decisions; it does not justify predicting that no Regulation citation can appear later in 2026.

A standardisation request, a draft delivered by CEN/CENELEC, publication of an EN standard and citation in the Official Journal are separate events. Only the applicable published legal reference establishes the cited presumption and its scope. Record the decision and date actually found; an anticipated year-end package is not a deadline or a current legal entitlement.

What gives presumption of conformity for safety sensors right now?

For machinery assessed under Directive 2006/42/EC, Decision (EU) 2023/1586 as amended is the relevant machinery standards decision. Follow the Commission index to the original decision and subsequent amendments. Check withdrawals and restrictions for each reference instead of assuming that the entire historical list remains unchanged until January 2027.

Separate three different jobs in the technical file. Device design and testing, the safety-related control function, and installation geometry use different standards. The following families are a navigation aid, not a declaration that every part or newest edition is cited:

• IEC/EN IEC 61496 family — general and technology-specific ESPE design/testing requirements. Check the exact EN part, edition and legal citation; a Type label alone is not the citation.
• ISO/EN ISO 13855 — safeguard positioning and dimensioning. The current international edition is 2024; verify the exact EN reference and its OJ status separately. A generic K×T+C subtotal does not cover every application.
• EN ISO 13849-1 / EN IEC 62061 — control-function design and verification. Match the exact edition, amendments, covered requirements and OJ conditions rather than treating all versions as interchangeable.

Decision (EU) 2026/79 does not alter these machinery references. Nevertheless, individual machinery references can have restrictions or withdrawal dates before the legislative transition. Use the version that is applicable to the product and date, and document any essential requirements not covered by the cited standard.

Will EN ISO 13849-1 and EN IEC 62061 move to the Regulation list?

A Regulation-supporting edition may follow the Directive edition, but legal presumption does not transfer merely because the standard number is familiar. Check the published reference under the relevant legal act and the essential requirements it covers. This article does not promise a future list, its contents or its publication date.

Read the Annex Z mapping in the exact EN edition you use. Its designation and scope depend on the document; do not assume every standard uses the same ZA/ZB arrangement. Mapping to Regulation requirements helps explain coverage, but it is not a substitute for a corresponding Official Journal citation.

Decision (EU) 2024/1329 added EN ISO 13849-1:2023 under the Machinery Directive and scheduled removal of the older reference for 15 May 2027. That reference-level date must not be interpreted as an extension of the Directive beyond the Regulation transition. Compare the underlying control-system methods in the PL versus SIL guide, and check the applicable legal citation separately.

What should a machine builder do in 2026 about the standards list?

Keep the conformity work boring and current. Concretely, for the rest of 2026:

• Determine the legal framework for the intended placing-on-market or putting-into-service date, then record the relevant machinery standards decision and amendments.
• For each standard record the full EN reference, restrictions and withdrawal date. Keep reference-level transitions separate from the general legislative application date.
• Check the Official Journal for references supporting the Machinery Regulation before claiming that presumption for products under the Regulation. Do not replace an actual citation with an expected publication date.
• Read the full legal-act title before reacting to any OJ entry. A number like 2026/79 can look relevant and be about a completely different directive.
• For a DQT4 light curtain or another selected device, retain the exact safety manual, declaration and certificate scope. Check integration and current design requirements independently of the standards list.

Retain the engineering evidence as well as the legal mapping. Review the Regulation changes, the safety-scanner device requirements and the positioning assessment. A legal transition is not proof that all design requirements, editions or certificate conditions remain unchanged.

Does the standards transfer mean my safety sensors need recertifying?

A standards-list change alone does not establish either a universal recertification duty or a universal exemption. Check the exact certificate, design and software version, expiry, legislative scope and applicable conformity assessment route. A component and the finished machinery may each have their own obligations.

Article 52(2) of the current Machinery Regulation preserves Directive EC type-examination certificates and approval decisions until expiry. That provision does not certify an unassessed product or permit every future unit under the old legislation. Ordinary DLD-series LiDAR is non-safety sensing equipment, not a personnel-protection scanner; do not include it in a safety certificate claim.
