| BOE Publication | October 13, 2026 |
| Effective date | October 14, 2026 |
| Standards approved | Over 60 new or revised UNE standards |

| Year | 2026 |
If your company manufactures, installs, maintains or certifies products or installations in sectors such as air conditioning, energy, construction or telecommunications, you have work to do. The Resolution of October 1, 2026 from the Directorate General of Industrial Strategy publishes over 60 UNE standards approved by AENOR in September 2026, in compliance with Royal Decree 2200/1995.
Details matter: among the updates, high operational impact standards stand out such as UNE 100012 (air conditioning system hygienization) and UNE 100030 (Legionella prevention), in addition to standards on pressure equipment inspection and new standards on industrial decarbonization. Ignoring these updates can leave your company out of compliance if those standards are referenced by technical regulations.
What does this regulation establish?
The resolution publishes the official list of UNE standards approved by AENOR during September 2026. These standards are technical specifications that define design, manufacturing, installation, maintenance or safety requirements in different industrial sectors.
The sectors and highlighted standards covered by the resolution are as follows:
| Sector / Technical area | Standards / Highlighted updates |
|---|---|
| Air conditioning and hygienization | UNE 100012 (air conditioning system hygienization) — updated version |
| Legionella prevention | UNE 100030 (Legionella prevention and control) — updated version |
| Pressure equipment | Pressure equipment inspection standards — updated |
| Electrical installations | New standards and revisions on electrical installations |
| Railway applications | Technical standards for the railway sector |
| Fiber optics / Telecommunications | Standards on fiber optics and telecommunications components |
| Construction materials | Standards on materials and construction systems |
| Explosion protection | ATEX standards and protection in explosive atmospheres |
| Industrial decarbonization | New standards on decarbonization processes in industry |
Adoption of these standards is voluntary in origin. However, they become mandatory when referenced by technical regulations (industrial safety regulations, transposed European directives, etc.). At that point, products or installations that do not comply cannot be legally marketed or put into service.
Economic and operational impact
The real impact of these standards is not uniform: it depends on whether your company already applies the previous version and how much the requirements have changed. The main cost vectors are:
- Review and update of internal procedures: Companies applying UNE 100012 or UNE 100030 must verify whether their hygienization and Legionella control protocols remain compliant with the updated versions.
- Product or installation recertification: If a revised standard modifies testing or design requirements, already certified products may need a new conformity assessment.
- Update of technical documentation: Maintenance contracts, installation manuals and inspection records must reference the current versions of the standards.
- Technical staff training: Changes in pressure equipment or explosion protection standards (ATEX) may require updating the training of operators and technicians responsible.
- Opportunity in decarbonization: New standards on industrial decarbonization open the door to certifying processes and products aligned with sustainability objectives, which can be a commercial differentiator.
Who does it affect?
- Air conditioning and facility maintenance companies: Required to review their protocols in accordance with updated UNE 100012 and UNE 100030.
- Pressure equipment manufacturers and inspectors: Must verify compliance with new versions of inspection standards.
- Electrical sector installers and manufacturers: Affected by revisions in electrical installation standards.
- Railway sector companies: Manufacturers and operators of rolling stock and railway systems.
- Telecommunications operators and fiber optic manufacturers: Must review compliance of their products and networks with new standards.
- Construction companies and construction material manufacturers: Affected by updates in construction material standards.
- Industries with potentially explosive atmospheres (ATEX): Required to review their explosion protection measures.
- Industries in decarbonization process: Can benefit from new standards to certify their progress.
Practical example
A facility maintenance company that manages air conditioning systems for several office and hotel buildings currently applies the previous version of UNE 100012 for hygienization protocols and UNE 100030 for Legionella control.
With the entry into force of the updated versions on October 14, 2026, this company must:
- Review point by point what has changed in both standards compared to the version it currently applies.
- Update its operating procedures and maintenance records to reflect the new requirements.
- Communicate the changes to its clients if maintenance contracts make express reference to previous versions of the standards.
- Verify whether the competent health authority (which may reference these standards in facility authorizations) already requires the new version.
If this company does not update its procedures and suffers a Legionella outbreak in a facility it maintains, the reference to an obsolete standard in its documentation can aggravate its legal and civil liability to clients and authorities.
What should companies do now?
- Identify which standards from the list affect your activity: Review the complete list published in the BOE of October 13, 2026 and cross-reference with the sectors in which your company operates.
- Compare the previous version with the new one: For standards you already applied (especially UNE 100012, UNE 100030 and pressure equipment inspection), analyze what requirements have changed.
- Update procedures and technical documentation: Modify manuals, maintenance protocols and records so they reference the current versions.
- Review contracts with clients and suppliers: If contracts cite specific versions of UNE standards, update the references to avoid contractual conflicts.
- Evaluate need for recertification: Consult with your certification body whether regulatory changes require re-evaluating the conformity of your products or installations.
- Train technical staff: Especially in areas of pressure equipment, ATEX and air conditioning, where changes can affect safety procedures.
- Monitor regulatory references: Watch whether any of these standards is referenced soon by technical regulations, which would make compliance mandatory.
Frequently asked questions
Are the UNE standards approved in September 2026 mandatory?
Originally, UNE standards are voluntary adoption. However, they become mandatory when referenced by technical regulations (such as industrial safety regulations or transposed European directives). Companies must monitor whether any of the over 60 standards approved in September 2026 is referenced soon by regulatory standards that affect their sector.
What changes in UNE 100030 for Legionella prevention in 2026?
The resolution confirms that UNE 100030 has been revised and approved in September 2026, with entry into force on October 14. Companies applying this standard for Legionella control in their facilities must review the specific changes compared to the previous version and update their protocols. The technical documentation available at AENOR allows access to the full text of the new version.
When do the UNE standards from September 2026 come into force?
The resolution publishing the list of standards was published in the BOE on October 13, 2026 and came into force on October 14, 2026. From that date, the versions approved in September 2026 are the current versions of each standard.
What risks does a company face if it does not update its procedures to the new UNE standards?
If a UNE standard is referenced by a technical regulation and the company does not comply, it may face the inability to market its products, the withdrawal of facility authorizations and civil or criminal liability in case of accident or damage. In sectors such as Legionella or pressure equipment, applying an obsolete version of the standard can aggravate legal liability before the Administration and to third parties.
Where can I consult the full text of the UNE standards approved in September 2026?
The official list of standards is published in the BOE of October 13, 2026. The full text of each UNE standard can be purchased through AENOR, the body that develops and commercializes them.
