Sixteen technical standard projects that are today in public consultation will become, once approved, reference requirements for installations, equipment and processes in industrial and energy sectors. The Resolution of June 1, 2026 from the Directorate General of Industrial Strategy and Small and Medium-Sized Enterprises opens the public information period for these UNE standard projects that AENOR has in processing corresponding to May 2026.
The deadline for participating in the consultation ranges between 20 and 40 calendar days counted from the day following publication (that is, from June 11, 2026). Ignoring this process has a real cost: companies that do not participate lose the opportunity to influence the technical requirements they will have to comply with.
What does this regulation establish?
The resolution submits to public information the 16 UNE standard projects that AENOR has in processing. Below are all the technical areas covered:
| Thematic area | Description |
|---|---|
| Photoluminescent fire safety signaling | Technical requirements for evacuation and fire-fighting signaling with photoluminescent materials |
| Gas pipelines at different pressures | Standards for gas distribution and transport networks at different pressure levels |
| Legionella control | Procedures and technical requirements for prevention and control of Legionella bacteria in installations |
| Inspection of low-voltage electrical installations | Criteria and procedures for inspecting low-voltage electrical installations |
| Pressure equipment — Boilers | Technical requirements for industrial boilers subject to pressure |
| Pressure equipment — Refineries | Standards for pressure equipment in refinery environments |
| Pressure equipment — Cryogenic tanks | Specifications for cryogenic storage tanks |
| Pressure equipment — LNG terminals | Requirements for pressure equipment in liquefied natural gas terminals |
| Electric arc detection | Systems and devices for detecting electric arcs in installations |
| Rubber materials | Technical specifications for rubber materials in industrial applications |
| Digital archive | Requirements for management and preservation of files in digital format |
| Tourism | Technical standards applicable to the tourism sector |
The complete texts of all projects are available on AENOR's portal: https://srp.une.org/. Any company, professional or sector association can submit observations during the consultation period.
Once approved, these UNE standards acquire the character of mandatory regulatory reference or are incorporated as a technical requirement in sector regulations. They are not optional: non-compliance can result in problems in inspections, certifications and public procurement.
Economic and operational impact
The impact of these standards is not immediate, but it is predictable. Companies that participate now in the consultation can:
- Anticipate changes in their processes and equipment before they become mandatory
- Influence the final drafting of technical requirements to make them technically and economically viable
- Avoid costs of urgent adaptation once the final standard is approved
The sectors with the greatest potential economic impact are those of pressure equipment (boilers, refineries, cryogenic tanks, LNG terminals) and gas pipelines, where adaptation to new technical requirements can involve significant investments in equipment review, procedure updates and technical staff training.
In the field of Legionella control, companies with hot water installations, cooling towers or air conditioning systems should pay special attention: changes in control procedures can translate into new maintenance protocols and increased frequency of analysis.
For the low-voltage electrical installations sector, new inspection criteria may affect the timelines and costs of mandatory periodic reviews.
Who does it affect?
- Energy and gas sector companies: distributors, transporters and gas network operators; LNG terminal operators
- Chemical and petrochemical industry: refineries and plants with pressure equipment
- Installers and maintainers: of low-voltage electrical installations, fire safety systems and pressure equipment
- Building and facility managers: hotels, hospitals, shopping centers and any installation with water systems susceptible to Legionella
- Tourism sector companies: affected by specific UNE standards for tourism in processing
- Manufacturers and importers of rubber materials: for industrial applications
- Document management managers: companies with digital archive obligations
- Engineers, technicians and inspection bodies: that certify or inspect installations in the affected sectors
- Sector associations: that can submit collective observations on behalf of their members
Practical example
A hotel company with hot water installations and heated swimming pools is directly affected by at least two of the 16 projects in consultation: Legionella control and tourism.
If the new UNE standard for Legionella control tightens analysis protocols (for example, increasing sampling frequency or expanding control points), the hotel will need to review its preventive maintenance contract and possibly increase the water analysis budget. By participating now in the public consultation —through srp.une.org—, the hotel or its sector association can submit technical observations so that new requirements are proportionate and applicable to its type of installation.
The deadline to do so is between 20 and 40 calendar days from June 11, 2026. After that deadline, the standard moves toward approval without possibility of modification by those affected.
What should companies do now?
- Identify which projects affect them: Access srp.une.org and download the texts of relevant projects for your sector (gas, Legionella, pressure equipment, electrical installations, tourism, etc.).
- Calculate the available deadline: The consultation period is between 20 and 40 calendar days from June 11, 2026. Verify the exact deadline for each project on AENOR's portal.
- Analyze technical and economic impact: Review the proposed requirements with the technical team or maintenance manager to identify what operational changes their approval would imply.
- Submit observations if appropriate: If any requirement is technically unfeasible or disproportionate, submit formal observations through AENOR's portal before the deadline expires.
- Coordinate with the sector association: Collective observations carry more weight. Contact your sector association to coordinate a joint response.
- Plan future adaptation: Although the standard is not yet final, anticipate likely changes in processes, equipment and training to avoid urgent adaptation costs after approval.
Frequently asked questions
Where can I consult the texts of the 16 UNE standard projects in consultation?
The complete texts are available on AENOR's official portal: https://srp.une.org/. There you can download each project and submit observations within the established deadline.
How much time do I have to submit comments on the May 2026 UNE standard projects?
The consultation period ranges between 20 and 40 calendar days counted from the day following publication of the resolution, that is, from June 11, 2026. The exact deadline for each project is indicated on AENOR's portal.
Are UNE standards mandatory for companies?
UNE standards are generally voluntary, but acquire the character of mandatory regulatory reference when expressly cited in technical regulations or in public procurement specifications. Non-compliance can generate problems in inspections, certifications and contracts with the Administration.
What sectors are affected by the May 2026 UNE standard projects?
The 16 projects cover: photoluminescent fire safety signaling, gas pipelines, Legionella control, inspection of low-voltage electrical installations, pressure equipment (boilers, refineries, cryogenic tanks, LNG terminals), electric arc detection, rubber materials, digital archive and tourism.
What happens if my company does not participate in the public consultation of these UNE standards?
If you do not participate, the standard will move toward approval without incorporating your technical observations. Once approved, the requirements are final and you will have to adapt to them without possibility of modification. Participating now is the only way to influence the technical requirements you will have to comply with.
