ISO/IEC 23761:2021 defines accessibility-related conformance and discoverability requirements for EPUB publications, making it relevant for teams that publish, evaluate, or procure digital books and other EPUB-based content. The document helps organizations align technical publishing workflows with accessibility expectations, supporting documented evaluation, technical review, and compliance preparation. For product owners, QA teams, and procurement specialists, ISO/IEC 23761:2021 can serve as a practical reference when assessing whether EPUB content is structured and discoverable in ways that support broader user access needs.

Overview of ISO/IEC 23761:2021

ISO/IEC 23761:2021 focuses on the conformance and discoverability requirements associated with EPUB accessibility. In practice, it is most useful where digital publishing teams need a clear compliance reference for checking how EPUB publications are organized and how accessibility-relevant information can be found and evaluated. The title indicates a scope centered on publication-level requirements rather than general hardware or electrical testing, so it is typically used in technical validation, editorial quality workflows, and accessibility-oriented review processes.

Compliance applications of ISO/IEC 23761:2021

Organizations may use ISO/IEC 23761:2021 during product evaluation, publishing platform assessment, and accessibility review of EPUB files intended for libraries, education, corporate knowledge bases, or regulated content delivery. It can support verification activities by helping teams check whether EPUB publications meet expected conformance and discoverability criteria before release or procurement approval. In document control and QA workflows, the reference is useful when technical teams need to compare vendor-delivered content against an accessibility compliance reference and document the outcome of the review.

Importance of compliance with ISO/IEC 23761:2021

Compliance with ISO/IEC 23761:2021 can improve consistency in EPUB accessibility testing and reduce risk in digital publishing programs. Clear requirements support engineering validation, conformity assessment preparation, and procurement decisions by giving stakeholders a defined basis for technical review. For organizations managing content quality, the document helps standardize checks across publications and supports more reliable reporting during regulatory preparation or internal audits. It is especially useful where accessibility performance and discoverability are part of operational quality assurance.
