Glossary of Technical & Engineering Standard Terms

Explore essential definitions, acronyms, and terminology used across international technical standards, codes, specifications, and Standards Developing Organizations (SDOs).

  • Addendum: An additional or supplemental publication attached to an existing technical document or standard, typically placed at the end, to add specifications or updates (plural: addenda).
  • Amendment: A formal change, addition, or deletion made to an active standard or code to refine content, clarify guidelines, or correct technical details.
  • Corrigendum: An official list of technical or typographical error corrections issued for a published document, book, or technical standard (plural: corrigenda).
  • DIS (Draft International Standard): A preliminary draft of an international standard (such as ISO or IEC) released to member bodies and the public for review and voting prior to official publication.
  • DRM (Digital Rights Management): Access-control technologies used by publishers and copyright holders to limit authorized access, copying, and distribution of digital standards files.
  • EN (European Normalization / European Standard): Technical standards ratified and approved for standardized application across member states within the European Union (EU).
  • Erratum: An official notice issued on a separate page or slip inserted into a publication to correct a published error; equivalent to a corrigendum (plural: errata).
  • FDIS (Final Draft International Standard): The final stage draft of an international standard distributed for a final formal vote among national member bodies before commercial publication.
  • FileOpen Plugin: A third-party security plugin required by major standards publishers to authenticate, open, and read DRM-protected Secure PDFs (SPDFs).
  • Hard Copy: A physical, paper-printed edition of an engineering code, standard, or technical manual.
  • ICS (International Classification for Standards): An international hierarchical classification framework designed to categorize technical standards across global industry sectors and economic activities.
  • ISBN (International Standard Book Number): A standardized, unique 13-digit commercial identifier assigned to books, technical manuals, and printed industry guides for global inventory tracking.
  • International Adoption: The process where international standard organizations (e.g., ISO, IEC) create a standard that is subsequently adopted regionally (e.g., European Norm EN ISO) or nationally (e.g., British Standard BS EN ISO, German Standard DIN EN ISO). Adopted versions maintain uniform technical specifications across languages.
  • Multi-User Access: Enterprise licensing models providing simultaneous online access to controlled technical document libraries across multiple team members or corporate departments.
  • Normative Reference: A mandatory external standard, code, or specification referenced within a primary document that must be fully complied with to achieve full standard compliance.
  • PDF (Portable Document Format): A standard electronic file format available for immediate digital download and viewing across desktop and mobile platforms without specialized security plugins.
  • POD (Print on Demand): A customized printing service provided by E-Standards Portal where hard-copy documents unavailable in standard digital format are custom-printed and dispatched immediately.
  • Printed Edition: A physical paper copy of an official engineering standard, code, specification, or technical report.
  • (R with Date) - Reaffirmed Standard: Indicates that an existing standard was formally reviewed by its technical committee and reaffirmed as technically valid without requiring content revisions.
  • RP (Recommended Practice): An authoritative document containing industry recommendations, practical advice, and proven procedure guidelines for specific engineering processes.
  • Redline Document (Redlines): A visual comparison document explicitly highlighting additions, deletions, and structural revisions between an updated standard and its previous edition.
  • Referenced Documents: A comprehensive list contained within a standard detailing both normative (mandatory compliance) and informative (supplementary guidance) external references.
  • SDO (Standards Developing Organization): An accredited entity or professional organization (such as ISO, IEC, ASME, IEEE, or ASTM) dedicated to developing, approving, updating, and maintaining industry standards.
  • SPDF (Secure Portable Document Format): An encrypted PDF file protected by Digital Rights Management (DRM) to prevent unauthorized distribution or printing, requiring the FileOpen plugin to view.
  • Single-User License: A standard digital license authorizing a single user to store, access, and view a downloaded standard on one designated device.
  • Standard: An officially consensus-driven set of technical requirements, guidelines, or specifications designed to ensure quality, safety, performance, and global interoperability.
  • Subscription Service: A custom web-based enterprise solution delivering multi-user online access to centralized document libraries and live standards updates.
  • Supplement: A formal extension or continuing section added to a standard to update specifications, address new technologies, or correct published errors.
  • TIR / TR (Technical Information Report / Technical Report): An informative document providing technical data, research findings, or operational guidance distinct from formal normative standard specifications.
  • Withdrawn Standard: A legacy standard no longer maintained or updated by its originating SDO committee. Although superseded or inactive, withdrawn standards frequently remain in active operational use for legacy equipment.
  • ZIP File Archive: A compressed file format used to consolidate and reduce the digital footprint of multiple document downloads for efficient transfer and storage.
