If your company certifies machinery, electrical equipment, cables or food products under UNE standards, this change affects you right now. The General Directorate of Industrial Strategy has published, in accordance with Royal Decree 2200/1995, the list of 22 UNE standards annulled during June 2026 at the proposal of AENOR. The annulment is effective from July 7, 2026.
This is not a minor wording change: annulled standards cease to be valid references for certifications, quality audits and CE marking. Continuing to cite them in technical documentation or contracts can generate non-conformities with legal and commercial consequences.
What does this regulation establish?
The resolution publishes the official list of UNE standards that AENOR has proposed to cancel for being obsolete, superseded or withdrawn from the regulatory system. Once published in the BOE, these standards cease to have validity as a recognized technical reference.
Among the most relevant annulled standards for the Spanish industrial sector, the following stand out:
| UNE Reference | Scope |
|---|---|
| UNE-EN ISO 13849-1 | Safety of machinery — Safety-related parts of control systems |
| UNE-EN 50436 | Breathalyzers for use in motor vehicles |
| Standards on optical fiber cables | Technical specifications for optical fiber cables |
| Standards on power transformers | Technical requirements for power transformers |
| Standards on pesticide detection in fatty foods | Analysis and detection methods in food laboratory |
| Standards on electrical insulation coordination | Insulation coordination criteria in electrical installations |
The total number of annulled standards amounts to 22. Companies that have them referenced in their internal procedures, technical sheets, contracts or certification files must identify the current versions that replace them and update all affected documentation.
Economic and operational impact
The annulment of UNE standards does not generate a direct automatic penalty, but it can trigger significant economic and operational consequences on three fronts:
- Quality audits: If a management system (ISO 9001, ISO 45001, etc.) references annulled standards, the auditor may issue a non-conformity. Resolving it involves time and costs for documentary review.
- CE marking: Manufacturers declaring conformity with harmonized standards must ensure that the references in their Declaration of Conformity correspond to current versions. An annulled reference invalidates the declaration.
- Contracts and specifications: Many industrial contracts and public tenders require compliance with specific technical standards. Citing an annulled standard can be grounds for contractual breach or exclusion from tenders.
The cost of updating varies depending on the number of affected standards and the complexity of the certified processes, but in all cases it is less than the cost of a non-conformity detected in an audit or losing a contract due to outdated technical documentation.
Who does it affect?
- Industrial machinery manufacturers that certify safety systems under UNE-EN ISO 13849-1.
- Breathalyzer manufacturers for motor vehicles using UNE-EN 50436.
- Companies in the electrical sector working with power transformers or electrical insulation coordination.
- Telecommunications operators and installers using optical fiber cable specifications.
- Agri-food laboratories applying standardized methods for pesticide detection in fatty foods.
- Quality and certification departments of any industrial company maintaining references to these standards in its documentary system.
- Technical advisors and certification consultants managing conformity files for industrial clients.
Practical example
An industrial machinery manufacturer has its safety system certified under the standard UNE-EN ISO 13849-1 and the reference appears in its CE Declaration of Conformity and in the equipment technical manual.
As of July 7, 2026, that reference corresponds to an annulled standard. If the manufacturer submits its machinery to a certification renewal audit or if a customer requests verification of equipment conformity, the reference to an annulled standard may generate a major non-conformity.
The correct action is: identify the current version that replaces the annulled UNE-EN ISO 13849-1, update the CE Declaration of Conformity, review the technical manual and notify the notified body of the change if the certification is third-party. This process, if well managed, can be resolved in days; if detected in an audit without prior preparation, it can halt equipment commercialization.
What should companies do now?
- Identify which annulled standards your company uses: Review the documentary system (procedures, technical sheets, Declarations of Conformity, contracts) and locate references to the 22 standards annulled in June 2026.
- Locate the current replacement versions: Consult the AENOR/UNE catalog to identify which active standard replaces each of the annulled ones.
- Update technical documentation: Modify CE Declarations of Conformity, technical manuals, quality procedures and any contractual document citing the annulled standards.
- Notify notified bodies if applicable: If the certification involves a third-party notified body, communicate the change in regulatory reference to maintain the validity of the certificate.
- Review current contracts and specifications: Check if any ongoing contract requires compliance with any of the annulled standards and manage the update of references with the other party.
- Establish a regulatory monitoring process: The annulment of standards is a continuous process. Implement a periodic monitoring system to detect future annulments before they affect active certifications.
Frequently asked questions
What specific UNE standards have been annulled in June 2026?
The resolution published on July 7, 2026 includes 22 annulled UNE standards. Among the most relevant are UNE-EN ISO 13849-1 (machine safety), UNE-EN 50436 (breathalyzers for vehicles), standards on optical fiber cables, power transformers, pesticide detection in fatty foods and electrical insulation coordination. To consult the complete list, access the official resolution in the BOE.
What happens if my company continues to use an annulled UNE standard in its documentation?
Using an annulled standard as a technical reference can generate non-conformities in quality audits, invalidate a CE Declaration of Conformity and constitute breach in contracts or tenders requiring specific regulatory compliance. There is no direct automatic administrative penalty, but the commercial and contractual consequences can be significant.
When do the June 2026 annulments take effect?
The annulments are effective from July 7, 2026, the date of publication of the resolution in the BOE. There is no additional adaptation period: from that date, the 22 standards cease to be valid technical references.
Where can I find the current standards that replace the annulled ones?
The current versions that replace the annulled standards can be consulted in the official AENOR/UNE catalog. Each annulled standard usually has a revised version or an equivalent standard that replaces it. It is recommended to verify directly with AENOR what the exact replacement reference is for each case.
Does this annulment affect the CE marking of products already on the market?
Products already on the market with CE marking do not automatically become non-compliant, but if the manufacturer renews the certification, updates the Declaration of Conformity or submits the product to a new audit, it must reference the current standards. Maintaining a reference to an annulled standard in the active CE Declaration of Conformity can be questioned by market surveillance authorities.
