Overview
SIST ISO 5658-2:2018/A1:2026 is the Slovenian adoption of the international amendment to ISO 5658-2:2006, focusing on fire testing for building and transport products. Specifically, this amendment refines procedures for measuring the lateral spread of flame on materials arranged in a vertical configuration. Reaction to fire testing is a critical part of fire safety standards, especially for construction materials and products used in transportation environments, ensuring regulatory compliance and enhanced public safety.
This amendment introduces clarified calculation methods and supplemental guidance to improve accuracy and global harmonization, particularly aligning with IMO (International Maritime Organization) fire testing protocols.
Key Topics
- Lateral Spread of Flame: The document details testing procedures for evaluating how flames spread laterally across building and transport products positioned vertically.
- Test Method Adjustments: Amendments include a clarification for the longest time used in heat measurement calculations, aligning calculations with IMO standards for increased consistency.
- Inter-laboratory Validation: Data was gathered through an inter-laboratory trial conducted by ISO/TC 92/SC 1/WG 3, involving a variety of materials such as plywood, gypsum board, and polycarbonate sheets.
- Measurement Repeatability and Reproducibility: The amendment provides additional tables summarizing the consistency and reliability of test results across participating laboratories, referencing ISO 5725-2 for measuring accuracy and repeatability.
Applications
The amended standard is directly applicable to:
- Construction Materials: Building products such as insulation boards, gypsum boards, particleboards, and metallic products intended for use in vertical applications.
- Transport Sector: Materials and composite products used in vehicles, public transport, ships, and trains, where stringent fire reaction properties are essential for passenger safety.
- Laboratory Testing: Accredited laboratories performing reaction to fire tests for the certification and regulatory approval of building and transport materials.
- Regulatory Compliance: Manufacturers and suppliers seeking compliance with European and international fire safety requirements benefit from harmonized procedures and reliable, repeatable testing outcomes.
- Material Development: R&D teams use these standardized testing methods during the development and improvement of fire-resistant materials and products.
Related Standards
For a comprehensive understanding of fire reaction testing and to ensure full compliance, consider the following related standards:
- ISO 5658-2:2006: The main international standard for fire reaction tests - spread of flame, outlining the baseline method updated by this amendment.
- ISO 5725-2:1994: Standard covering accuracy (trueness and precision) of measurement methods and results, crucial for understanding and applying repeatability and reproducibility results.
- IMO Resolution A.653(16): An important international maritime reference harmonized in this amendment to ensure global consistency in fire safety testing.
- ICS 13.220.50: The International Classification for Standards code relevant to fire-resistance of building materials and elements.
Adhering to SIST ISO 5658-2:2018/A1:2026 supports the safe specification, use, and certification of fire-safe materials in essential built environments, promoting both public safety and regulatory confidence.

Avant-propos
L’ISO (Organisation internationale de normalisation) est une fédération mondiale d’organismes nationaux de
normalisation (comités membres de l’ISO). L’élaboration des Normes internationales est en général confiée aux
comités techniques de l’ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du comité
technique créé à cet effet. Les organisations internationales, gouvernementales et non gouvernementales,
en liaison avec l’ISO participent également aux travaux. L’ISO collabore étroitement avec la Commission
électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI, Partie 2.
La tâche principale des comités techniques est d’élaborer les Normes internationales. Les projets de Normes
internationales adoptés par les comités techniques sont soumis aux comités membres pour vote. Leur publication
comme Normes internationales requiert l’approbation de 75 % au moins des comités membres votants.
L’attention est appelée sur le fait que certains des éléments du présent document peuvent faire l’objet de droits
de propriété intellectuelle ou de droits analogues. L’ISO ne saurait être tenue pour responsable de ne pas avoir
