If your company manufactures machinery, installs electrical substations, operates in the railway sector or issues electronic invoices, you have work to do before your next certifications or procurement processes arrive on the table. The Resolution of July 1, 2026 from the General Directorate of Industrial Strategy, published in the BOE on July 7, contains the official list of UNE standards approved during June 2026 in compliance with Royal Decree 2200/1995. There are more than 50 standards effective as of July 8, 2026.
What does this regulation establish?
The General Directorate of Industrial Strategy publishes monthly the list of UNE standards that the Spanish Association for Standardization (UNE) has approved. These standards are not recommendations: when referenced in technical regulations, public contracts or product certifications, their compliance becomes mandatory or determinant for accessing markets and procurement processes.
The standards approved in June 2026 cover the following sectors and highlighted technical areas:
| Technical area | Highlighted standards | What it regulates |
|---|---|---|
| High voltage electrical installations | UNE 192014-1 and UNE 192014-2 | Inspection of electrical substations |
| Electronic invoicing | UNE-EN 16931-1 | Semantic model of electronic invoice |
| Railway applications — Accessibility | Standards for PRM (Persons with Reduced Mobility) | Railway accessibility for PRM |
| Industrialized construction | Various standards from the June block | Industrialized construction standards |
| Machinery safety | Various standards from the June block | Safety requirements for manufacturers |
| Household appliance safety | Various standards from the June block | Safety requirements for household appliances |
| Solid biofuels | Various standards from the June block | Technical standards for solid biofuels |
The most operationally relevant updates are those for electrical substation inspection (UNE 192014-1 and UNE 192014-2), the semantic model of electronic invoice (UNE-EN 16931-1) and the railway accessibility standards for persons with reduced mobility.
Economic and operational impact
The approval of new versions of UNE standards has direct consequences in three business areas:
- Product certifications: If your product or installation is certified under a previous version of any of these standards, the certification body may require a review or recertification under the new version. This involves audit costs and, in some cases, product redesign.
- Public procurement: Technical specifications for public contracts typically reference current UNE standards. A company that has not updated its technical documentation to the new versions may be excluded from tenders or suffer contractual penalties.
- Liability for defective products: Non-compliance with updated technical standards can be used as evidence of negligence in claims for damages, especially in sectors such as machinery, household appliances or electrical installations.
In the specific case of UNE-EN 16931-1 (semantic model of electronic invoice), companies that develop or integrate invoicing software must verify that their systems are compatible with the new version of the standard, especially regarding the mandatory B2B electronic invoicing being deployed in Spain.
Who does it affect?
- Industrial machinery manufacturers: Must review the new machinery safety standards approved in June 2026 and verify if they affect their CE declarations of conformity.
- Electrical substation installation and operating companies: UNE standards 192014-1 and 192014-2 update inspection criteria; affects companies in the energy sector and their inspection service providers.
- Railway sector operators and manufacturers: New accessibility standards for PRM affect rolling stock, infrastructure and railway services.
- Construction and industrialization companies: Industrialized construction standards update applicable standards for prefabricated or modular building projects.
- Household appliance manufacturers: Must review new safety standards to verify if their products require updated testing or certifications.
- Solid biofuel producers and distributors: New technical standards may affect product specifications and quality controls.
- Invoicing software and ERP developers: The update to UNE-EN 16931-1 directly impacts the implementation of the electronic invoice semantic standard.
- Certification and inspection bodies: Must update their audit and testing procedures to the new normative versions.
Practical example
An electrical substation installation company specializing in high voltage that performs periodic inspections for energy sector clients has its inspection procedures documented according to the previous version of UNE 192014 standard. With the approval of the new UNE 192014-1 and UNE 192014-2 on July 8, 2026, its inspection reports must be updated to reference and comply with the new technical criteria.
If this company participates in a public procurement process announced after August 2026 and presents technical documentation based on the previous version of the standard, the tender specifications may reject its offer for not complying with current technical regulations. The cost of updating internal procedures (document review, technical team training and, if applicable, new certification audit) is significantly lower than the cost of losing a public contract.
What should companies do now?
- Identify which standards from the June 2026 list affect your activity: Consult the complete list published in the BOE and cross-reference the covered sectors (high voltage, machinery, railway, construction, household appliances, biofuels, electronic invoicing) with your main activity.
- Review current certifications: Check if any of your product or system certifications reference previous versions of the now-updated standards. Contact your certification body to learn about transition timelines.
- Update technical documentation and declarations of conformity: If you manufacture machinery or household appliances, review whether the new safety standards require updating your CE declaration of conformity or the type tests performed.
- Verify compatibility of invoicing systems with UNE-EN 16931-1: If you develop or use electronic invoicing software, confirm with your provider that the new version of the semantic model is implemented or on the roadmap.
- Update specifications and technical requirements in contracts: If you are a buyer or contractor, review that the technical specifications of your current or upcoming contracts reference the normative versions in force as of July 8, 2026.
- Train your technical team: Ensure that those responsible for quality, engineering and compliance are aware of the changes introduced by the new normative versions that affect them.
Frequently asked questions
When do the new UNE standards from June 2026 take effect?
The UNE standards approved in June 2026 and published through the Resolution of July 1, 2026 became effective on July 8, 2026, one day after their publication in the BOE (July 7, 2026).
What happens if my company continues to use the previous version of an updated UNE standard?
Non-compliance with new normative versions can have three main consequences: problems in product or system certification processes, exclusion or penalties in public procurement that reference current standards, and greater exposure to civil liability for defective products if it is demonstrated that updated technical standards were not followed.
Which sectors are affected by the UNE standards approved in June 2026?
The affected sectors are: industrialized construction, high voltage electrical installations (especially substation inspection, with standards UNE 192014-1 and UNE 192014-2), machinery safety, railway applications for persons with reduced mobility (PRM), electronic invoicing (UNE-EN 16931-1), household appliance safety and solid biofuels.
Does the update to UNE-EN 16931-1 require changing my invoicing software?
UNE-EN 16931-1 defines the semantic model of the electronic invoice. Its update means that invoicing systems must be compatible with the new version of the standard. If your company uses an ERP or invoicing software from an external provider, you must verify with them if they have already implemented or plan to implement the update. It is especially relevant regarding the mandatory B2B electronic invoicing in Spain.
Where can I find the complete list of the more than 50 UNE standards approved in June 2026?
The complete list is published in the BOE with reference BOE-A-2026-14741, corresponding to the Resolution of July 1, 2026 from the General Directorate of Industrial Strategy and Small and Medium-Sized Enterprises. You can also purchase the complete text of each standard through UNE (Spanish Association for Standardization).
