Overview
SIST EN ISO 13943:2024 is the Slovenian adoption of EN ISO 13943:2023 / ISO 13943:2023, the international vocabulary for fire safety. This fourth edition updates and expands the standardized fire safety vocabulary used across ISO and IEC standards. The document defines general and specialized terms used in fire testing, fire safety engineering, building and civil engineering, and related disciplines - supporting consistent language across standards, regulations and technical reports.
Key topics and technical content
The standard:
- Provides alphabetical, standardized terms and definitions covering fundamental concepts, fire testing and fire safety engineering. Preferred terms are highlighted (bold) with admitted/deprecated variants listed.
- Includes revised and new entries - the 2023 edition adds or revises a large number of terms (86 changes noted vs. the previous edition).
- Covers examples of technical terms such as activation time, active fire protection, aerosol, afterglow, alarm time, auto‑ignition and many more (extracts show precise, standardized definitions).
- References related standards and resources used in development and implementation, e.g. ISO 10241‑1:2011 (layout), ISO 6182‑7:2020 (measurement methods referenced for actual delivered density), and the ISO/IEC terminology platforms (ISO OBP and IEC Electropedia).
- Notes on scope and use: definitions reflect language used in ISO/IEC documents and may differ from regulatory definitions; the document contains no normative references.
Practical applications and intended users
ISO 13943 is essential for anyone who needs a common, authoritative fire safety vocabulary to avoid ambiguity and ensure interoperability:
- Fire safety engineers and consultants applying performance-based design.
- Standards writers and technical committees (ISO/TC 92, CEN/TC 127) for developing harmonized standards.
- Testing laboratories and certification bodies that report results consistent with international terms.
- Building designers, architects and civil engineers integrating fire safety requirements into projects.
- Manufacturers of fire protection systems and components (sprinklers, suppression agents, detectors).
- Regulators, code authorities, insurers and fire services who rely on consistent terminology in specifications, codes and incident reporting.
- Educators and researchers working in fire science, combustion and human safety.
