Monthly Roundup: Key Information Technology Standards from September 2025

Looking back at September 2025, the Information Technology sector experienced a dynamic month for international standardization, with five major standards released that set the pace for terminology, interoperability, digital accessibility, cabling infrastructure, and data structuring. This overview offers industry professionals and compliance specialists a comprehensive look at each publication, highlighting their implications and common themes. For those striving to stay ahead amid regulatory evolution and technological advancement, this article delivers a detailed, practical summary and contextual analysis of the month’s standards.

Monthly Overview: September 2025

September 2025 stood out as a month of strategic progression in Information Technology standardization. The sector saw the release of five influential standards, addressing both emerging fields—like brain–computer interfaces (BCI)—and critical infrastructure foundations such as generic data cabling and building information modelling (BIM). Notably, major updates in B2B electronic invoicing and the adoption of the latest WCAG 2.2 guidelines echoed the industry’s embrace of interoperability, accessibility, and digital transformation. This cluster signaled intensified efforts to provide clear vocabulary for cutting-edge domains, ensure inclusive access, and foster seamless data exchanges across business and asset life cycles.

Of particular note, September’s publications reflected three central trends:

• Unification of terminology for disruptive technologies (e.g., BCI)
• Expansion of digital enablement through accessibility and interoperability standards
• Deeper convergence of physical and digital asset management, seen in both cabling models and BIM data structuring

Comparatively, this level of diversity indicates a maturing landscape, where standards bodies are pivoting to support both traditional IT infrastructure and evolving digital services.

Standards Published This Month

ISO/IEC 8663:2025 - Information Technology - Brain-computer interfaces - Vocabulary

Information technology – Brain–computer interfaces – Vocabulary

Addressing a rapidly growing interdisciplinary field, ISO/IEC 8663:2025 established a unified vocabulary for brain–computer interfaces. Its scope is remarkably broad, covering fundamental concepts, system components (sensors, transducers, effectors), modalities (invasive, non-invasive, hybrid), experimental designs, feedback mechanisms, protocols, signal processing methods, and a wide range of BCI application areas.

For manufacturers, developers, and researchers in the BCI domain, this standard now serves as the essential reference, enabling consistent communication, reducing misunderstandings, and supporting cross-disciplinary collaboration. It integrates with both Information Technology and neuroscience lexicons, ensuring that regulatory, procurement, and academic documentation can speak a common language.

Notable aspects include precise differentiation between BCI types (e.g., active vs. passive, invasive vs. non-invasive), system architecture elements like channels/electrodes, and special concepts such as bidirectional interfaces and collaborative BCIs.

Key highlights:

• Establishes a standardized, authoritative glossary for BCI terminology
• Covers the entire chain: from theoretical concepts to real-world application
• Enables aligned communication across industries, academia, and regulation

CEN/TR 16931-10:2025 - Electronic invoicing – Part 10: Additional requirements to extend to B2B

Electronic invoicing – Part 10: Additional requirements to extend to B2B

CEN/TR 16931-10:2025 addressed a long-standing gap in e-invoicing standardization by explicitly extending the EN 16931 electronic invoicing framework—originally focused on B2G (business-to-government)—to support B2B usage across Europe. Built upon the technical guidelines of CEN/TR 16931-5, this standard tackles unique B2B business process needs, interoperability challenges in multi-sector environments, and semantic model extension requirements.

It introduces:

• A structured methodology for extending core invoice elements
• Principles for sector/country-specific adaptations,
• Guidelines on creating, maintaining, and governing extension components

For businesses, especially those operating pan-Europe, CEN/TR 16931-10:2025 brings clarity to the previously fragmented landscape by supporting uniform B2B invoicing processes. It’s crucial for:

• Finance, trade, and IT solution providers,
• Companies integrating automated accounts payable/receivable systems,
• Standards professionals involved in e-invoicing compliance

The report also offers practical governance frameworks and maintenance cycles for extension management, reducing risks related to interoperability breakdowns and future-proofing e-invoicing investments.

Key highlights:

• Maps the extension of EN 16931 to B2B scenarios, ensuring consistency
• Provides governance models and methodologies for handling extensions
• Enables improved e-invoice adoption and interoperability for all business sizes

This update directly impacts:

• Public and private organizations with digital customer-facing platforms
• Web developers, designers, UX professionals, and content managers
• Accessibility auditors, legal teams, and compliance officers

ISO/IEC 40500:2025 is now essential for global digital compliance—ensuring organizations implement accessible websites and applications meeting legislative mandates, such as the European Accessibility Act, Section 508 in the US, and national disability regulations worldwide.

Key highlights:

• Updated and formalized new and revised WCAG 2.2 criteria
• Mandates international best practices for universal web accessibility
• Facilitates legal, reputational, and usability compliance globally

Common Themes and Industry Trends

A review of September 2025’s publications unveils pervasive focus areas:

• Interoperability and Data Consistency: Multiple standards, especially in BIM (ISO 23387:2025) and e-invoicing (CEN/TR 16931-10:2025), emphasize harmonized data models and extensibility, reinforcing a shift towards frictionless digital collaboration and procurement.

• Accessibility and Inclusion: The formalization of WCAG 2.2 (ISO/IEC 40500:2025) solidifies accessibility as a requirement—not an option—across IT services, mirroring user-centric and regulatory expectations.

• Terminology Unification for New Technologies: ISO/IEC 8663:2025 provides a critical touchpoint for the nascent BCI ecosystem, paving the way for international alignment as research, products, and regulation converge.

• Lifecycle Enablement and Asset Digitalization: Both cabling (ISO/IEC TS 11801-9903:2025) and BIM standards reflect the growing demand for standards that bridge design, build, and operate phases—vital in smart buildings, IoT deployments, and digital twins.

Sector-wise, ICT infrastructure, e-business, web and software developers, civil engineering, and neuroscience/healthcare technology all featured in this month’s standardization activities.

Compliance and Implementation Considerations

For organizations impacted by these standards, consider the following practical guidance:

• Start with a gap analysis:
  • Identify which new or revised requirements affect your products or processes, such as updated accessibility criteria or new data structures for BIM and e-invoicing.
• Prioritize implementation:
  • Accessibility (WCAG 2.2) often comes with regulatory deadlines—address compliance early.
  • For B2B e-invoicing, map your business processes to the new extension rules to ensure pan-European compliance.
  • Cabling infrastructure teams should recalibrate models and design tools to align with fresh SNR and transmission models.
• Engage with ecosystem partners:
  • Share and adapt the unified BCI vocabulary, especially in R&D and procurement communications.
  • For BIM, ensure vendors and external teams are using compatible data templates based on the latest standard.
• Resource Upgrades:
  • Update training, internal documentation, and procurement specs to refer to these latest standards.
  • Leverage XML schemas and implementation guides for system integration.
• Timeline and resource planning:
  • Plan for phased adoption, particularly when updates may cascade through supply chains and external partners.
  • Monitor regulatory environments for any harmonization requests or mandates referencing these new standards.
