This service offers standardized ignitibility testing of construction materials and products, assessing their ease of ignition when exposed to a small flame under controlled conditions. The Ignitibility Test provides essential data for the Euroclass fire classification system, especially for classes B to E under EN 13501-1, and is widely used for wall coverings, insulation boards, foams, fabrics, and surface finishes.
The method evaluates whether a material ignites, how rapidly flame spread occurs, and whether burning droplets or particles are produced. It simulates a typical fire-start scenario—such as contact with a match, lighter, or candle—and helps determine the potential of a material to contribute to fire development at its earliest stages.
The test is conducted according to EN ISO 11925-2, which specifies:
-
A small burner applies a flame (20 mm in length) for 15 or 30 seconds
-
The specimen is mounted vertically, with the flame applied to either the surface or edge
-
The after-flame time, flame spread height, and presence of burning droplets are recorded
The specimen dimensions are 90 mm × 250 mm, with a maximum thickness of 60 mm. The test is generally repeated several times to ensure statistical confidence and reproducibility.
This ignitibility test is often used as a pre-screening tool before larger-scale tests (e.g., SBI or Cone Calorimeter), and is a mandatory input for Euroclass classification under EN 13501-1.
NTUA’s fire testing laboratory operates under ELOT EN ISO/IEC 17025:2017 accreditation, ensuring full compliance and traceability. Results are presented in a detailed test report suitable for technical documentation, certification files, or regulatory submission.
