Is EN 13501-1:2007

EN 13501-1:2007 is a European standard that provides classification of the reaction to fire performance of construction products and building elements. It is an essential standard for assessing the fire safety of materials used in buildings. This article aims to provide a thorough explanation of the key aspects covered by this standard.

Scope and Purpose

The scope of EN 13501-1:2007 includes all products used in the construction of buildings, such as walls, floors, ceilings, roofs, doors, and windows. Its purpose is to determine the performance of these materials when exposed to fire. The standard defines different classes based on the materials' contribution to fire load, heat release, smoke production, and ability to resist ignitability, flame spread, and flaming droplets.

Testing Methods

The standard specifies the testing methods for evaluating the behavior of construction products under fire conditions. These tests are conducted in accredited laboratories using specific equipment and procedures. One of the key tests outlined in EN 13501-1:2007 is the Single Burning Item (SBI) test, which assesses the reaction to fire of a product when exposed to a controlled heat source.

In addition to the SBI test, other tests included in EN 13501-1:2007 evaluate parameters such as flame spread, heat release rate, smoke production, and production of flaming droplets. These tests provide valuable information for determining the fire hazard potential of construction materials and their suitability for use in different building applications.

Classification and Markings

Based on the test results, EN 13501-1:2007 classifies construction products into various Euroclasses, namely A1, A2, B, C, D, E, and F. The highest class, A1, indicates non-combustible materials with no contribution to fire. Class F represents products with the lowest fire resistance.

Products classified according to EN 13501-1:2007 are marked with relevant information, including the Euroclass achieved, any additional performance characteristics, and the notified body responsible for the initial assessment. These markings ensure transparency and enable architects, engineers, and regulatory authorities to make informed decisions regarding fire safety in buildings.


EN 13501-1:2007 is a vital standard in ensuring the fire safety of construction products and building elements. By providing clear classification and testing methods, it helps stakeholders assess the suitability of materials for use in different building applications. Compliance with this standard not only enhances fire safety but also promotes confidence in the built environment.
