# LVD harmonised standard update workflow

Workflow for checking Low Voltage Directive harmonised standard updates, affected products, withdrawal dates, presumption of conformity, retesting, technical files, and declarations.

*Workflow* *EU*

## EU Low Voltage Directive harmonised standard update workflow

Use this workflow when an OJEU publication or Commission implementing decision changes the LVD harmonised standards relied on by an electrical product.

It focuses on the practical work: check the official list, identify affected models, read withdrawal or restriction language, reassess presumption of conformity, and update the technical file and EU declaration.

LVD harmonised standards are voluntary, but once a product relies on one for presumption of conformity, a Commission update can change the evidence needed to keep that presumption. The workflow below turns each OJEU or implementing-decision update into a product-by-product review of standards, safety objectives, test evidence, technical documentation, and the EU declaration of conformity.

## Start with the official LVD standards sources

Track the Commission LVD harmonised-standards page, the consolidated implementing decision, and any amending decisions. Since the legal effect depends on publication of the reference in the Official Journal, do not treat a supplier bulletin or standards-body announcement as enough by itself.

- Record the Commission implementing decision number, OJ publication reference, affected standard number, amendment or corrigendum, and whether the entry is a publication, deletion, withdrawal, restriction, or notice.
- Use the Commission harmonised-standards overview to confirm that the page is about OJEU-published references, not merely voluntary standards catalogues.
- For LVD, check Implementing Decision (EU) 2023/2723 and later amending decisions because they consolidate many LVD standard references in one act.
- When the source gives an application or withdrawal date, copy that date exactly and tie it to the affected row and product family.

## Map each standards update to affected products

The impact review should start with a product-standard map, not with a general regulatory memo. Compare the standard number, part, amendment, corrigendum, title, restriction text, and product description against the models, variants, accessories, chargers, cables, assemblies, and installation conditions in the technical file.

- Flag exact matches where the technical file lists the updated standard in full or in part.
- Flag near matches where the product category, installation environment, accessory, or supplied component matches the OJEU row even if the product owner used a different internal naming convention.
- For each affected model, list the current test report, applied standard version, applied clauses, declared technical specifications, production-control evidence, and EU declaration reference.
- Separate withdrawn references from restricted references: a withdrawal removes the reference after the specified date, while a restriction can leave the standard listed but narrow the clauses or notes that confer presumption of conformity.

Sources for this answer:

- [Directive 2014/35/EU](https://eur-lex.europa.eu/eli/dir/2014/35/oj?ref=sorena.io) - Requires manufacturers to account for changes in product design, product characteristics, harmonised standards, international or national standards, or other technical specifications used to declare conformity.
- [Commission Implementing Decision (EU) 2025/1457](https://data.europa.eu/eli/dec_impl/2025/1457/oj?ref=sorena.io) - Example of an LVD amendment that withdraws one EN 60335 reference and keeps other EN 60335 references with restrictions or notices.
- [Commission Implementing Decision (EU) 2024/2764](https://data.europa.eu/eli/dec_impl/2024/2764/oj?ref=sorena.io) - Example of an LVD amendment adding revised references and deferring deletion of earlier references to give manufacturers time to adapt.

## Assess presumption-of-conformity impact before release

Article 12 gives presumption of conformity only for harmonised standards, or parts of standards, whose references are published in the OJEU and only for the safety objectives covered by those standards or parts. The review therefore has to answer whether the old evidence still covers the relevant Annex I safety objectives after the update.

- If the old reference remains valid until a stated withdrawal date, schedule the replacement review before that date and document whether current shipments rely on the old or new reference.
- If a restriction says a clause or note does not confer presumption of conformity, remove that clause or note from the presumption claim and decide what other test, analysis, design change, or technical specification will support the safety objective.
- If the Commission decision says the earlier reference no longer provides presumption of conformity for the product issue, treat the gap as a safety and conformity-assessment issue, not only as a documentation update.
- Use grounded dates only. Examples in the grounding include 13 June 2025 for withdrawal of EN 60335-2-24:2010 in Decision (EU) 2023/2723, 30 April 2026 for point (1) of the Annex in Decision (EU) 2024/2764, 18 January 2027 for point (1) of the Annex in Decision (EU) 2025/1457, and 23 January 2027 for point (1) of the Annex in Decision (EU) 2025/1488.

## Turn LVD standards updates into product evidence

Use the workflow to check OJEU updates, affected products, presumption-of-conformity gaps, retesting needs, technical file changes, and EU declaration updates before the next release or shipment review.

- [Open Research Copilot](/solutions/research-copilot.md): Check LVD standards changes and product evidence with cited outputs.
- [Talk through implementation](/contact.md): Review affected products, standards evidence, retesting scope, and declaration updates.

## Close the update with retesting, risk review, and file changes

A standards update is closed only when the product evidence has caught up with the presumption claim. For each affected product, decide whether the change requires retesting, partial clause testing, engineering analysis, supplier evidence, production-control checks, user-instruction changes, or a new declaration package.

- Update the technical documentation so it shows the applicable requirements, risk analysis and assessment, applied harmonised standards in full or in part, and the technical solution used where a harmonised standard is not applied or no longer supports the claimed safety objective.
- Keep old and new test reports traceable to product models, manufacturing revisions, firmware or control changes where relevant, critical components, and installation conditions.
- Review complaints, non-conforming equipment, recalls, sample testing, and distributor or importer feedback when the standards update concerns a hazard already seen in the field.
- Update the EU declaration of conformity when the standard list, Union acts, product identification, or conformity basis changes; the LVD requires the declaration to be continuously updated and kept with the technical documentation.
- Keep the review package for the same retention period as the technical documentation and EU declaration: 10 years after the electrical equipment has been placed on the market.
