Is EN 13501-1:2007 -


In order to ensure the safety of buildings, it is crucial to have a clear understanding of fire resistance and reaction of materials used in construction. One of the internationally recognized standards for assessing the fire performance of construction products is EN 13501-1:2007. This article aims to provide a simplified explanation of the key aspects covered by this standard.

Understanding EN 13501-1:2007

Scope of the Standard:

EN 13501-1:2007 outlines the classification system for the reaction to fire performance of construction products. It covers both vertical and horizontal applications, as well as products used in internal and external building elements. The standard provides a framework for evaluating the ability of a material to resist the spread of fire and the release of hazardous substances.

Fire Resistance Ratings:

EN 13501-1:2007 assigns different classes to construction products based on their performance during exposure to fire. These classes include A1, A2, B, C, D, E, and F, where A1 represents the highest level of fire resistance and F indicates no or limited fire resistance. The criteria for these classifications are determined by factors such as heat release, smoke production, flaming droplets, and duration of fire resistance.

Testing Procedures:

The standard specifies detailed testing procedures to determine the fire performance of construction products. These tests evaluate various properties of materials, including calorific value, flammability, and smoke production. The results obtained from these tests are then used to determine the appropriate class of the product according to the classification system mentioned earlier.


EN 13501-1:2007 is an important standard that provides a common basis for assessing the fire performance of construction products. By understanding this standard, professionals in the construction industry can make informed decisions regarding the materials and products they use. It helps ensure the safety and protection of buildings and their occupants in case of a fire.
