UNE Standards April 2026: How to Participate in the Public Consultation and Which Sectors Are Affected

Key data

The technical standards that are today in draft form are those that tomorrow will determine whether your company can participate in a public tender, obtain a certification or access certain European markets. The Resolution of April 30, 2026 from the General Directorate of Industrial Strategy opens the window for companies, associations and technical professionals to influence the UNE standard projects that AENOR has in process for April 2026.

This public information procedure is not mere formality: it is the only real opportunity to modify the content of a standard before it becomes final. Once approved, the UNE standard becomes the reference standard for the sector, and compliance may be required by customers, administrations or sector regulators.

What does this regulation establish?

The resolution submits to public information the UNE standard projects that AENOR has in process in April 2026. The procedure works as follows:

• The General Directorate of Industrial Strategy publishes the projects in process in the BOE.
• During the public consultation period, any company, sector association or individual can submit technical observations on the content of the drafts.
• AENOR collects and analyzes the contributions received before approving the final version of each standard.
• The approved standards become reference UNE standards for the corresponding sector.

UNE standards are voluntary standards that regulate technical requirements for products, services and processes. However, their voluntary nature does not mean they are irrelevant to companies: they can be required contractually by customers or business partners, required as a condition in public tenders, or imposed de facto by specific sector regulation.

Furthermore, UNE standards approved in Spain are frequently aligned with European standards (EN standards) and international standards (ISO/IEC standards), so their impact can extend to access to European and international markets.

Economic and operational impact

The impact of UNE standards on companies materializes in three main areas:

• Certifications: Many product, service or management system certifications take UNE standards as reference. A change in the standard may require adapting processes, documentation or products to maintain current certification.
• Public procurement: Public procurement specifications frequently require compliance with specific UNE standards. Companies that do not comply with new standards may be excluded from public tenders.
• Access to European markets: UNE standards harmonized with European standards condition the free movement of products in the EU internal market. A regulatory change can affect CE marking or other market access requirements.

Participating in the public consultation has no direct cost for companies, but it does have a clear opportunity cost: not participating means losing the opportunity to influence standards that will later have to be complied with, with the adaptation costs that entails.

Who does it affect?

This resolution is relevant to any company or professional whose activity is regulated or may be affected by technical standards. In particular:

• Manufacturers and industrialists: Companies that produce goods subject to technical requirements for product, safety or quality.
• Technical service companies: Organizations that provide services regulated by process or management standards.
• Sector associations: Entities that represent productive sectors and can submit collective observations on behalf of their members.
• Technical professionals: Engineers, quality technicians, R&D managers and other professionals who work with technical standards in their daily activity.
• Companies participating in public tenders: Organizations that need to comply with UNE standards as a requirement to access public contracts.
• Exporters and importers: Companies whose access to European markets depends on compliance with harmonized technical standards.

Practical example

Imagine a company manufacturing personal protective equipment (PPE) that currently complies with the current UNE standard for its product category. AENOR has in process in April 2026 a standard project that updates the technical requirements for that type of PPE.

If the company does not participate in the public consultation, the new standard will be approved without incorporating its practical experience or production needs. When the standard comes into force, the company will have to adapt its manufacturing process, materials or validation tests to comply with the new requirements, with corresponding adaptation costs.

If, instead, the company submits observations during the public information period, it can propose that certain requirements be more reasonable from a technical and economic point of view, or that appropriate transition periods be established. This participation does not guarantee that its proposals will be accepted, but it is the only formal way to try before the standard becomes final.

The same applies to a sector association representing several dozen manufacturers: a single well-argued collective contribution can have a significant impact on the final text of the standard.

What should companies do now?

1. Consult the complete list of projects in process: Access the resolution published in the BOE to identify which UNE standard projects are under public consultation in April 2026 and which affect your sector or activity.
2. Evaluate the potential impact of each project: Analyze whether the identified projects can affect your products, processes, current certifications or access to public tenders. Involve your technical or quality team in this evaluation.
3. Prepare and submit observations if appropriate: If any standard project could negatively affect your activity, or if you have technical contributions that would improve the draft, submit your observations to AENOR within the deadline established in the public consultation.
4. Coordinate with your sector association: If you belong to a sector association, share your analysis with it. A collective and well-supported contribution carries more weight than an individual one.
5. Plan for adaptation to future standards: Although the standards are still in process, anticipate possible changes in your processes, products or documentation to avoid urgent adaptation costs when the standards become final.
