Fire Testing Systems for Electronics and Polymers

Trusted Fire Testing Solutions for Polymers and Electronics by NETZSCH

From consumer devices to industrial equipment, polymers are essential for modern electronics ‒ but their fire behavior must be precisely understood.

NETZSCH fire testing instruments deliver accurate insights, e.g., into ignition resistance, heat release, smoke development, burning behavior and oxygen concentration, supporting manufacturers in meeting international fire safety standards and ensuring reliable product performance and protection. Furthermore, when coupled with the Bruker Omega 5 FT-IR system, the TCC 918 Cone Calorimeter can Identify and quantify toxic gases released during combustion.

We can also provide further variants and individual fire testing instruments according to customer requirements.

EN 13501 is the European standard for fire-classifying construction products and building elements.

As part of the EU’s harmonized approach to fire safety, it is used across all EU member states (and many associated countries) to determine how materials and building components behave in a fire. Materials are categorized into different classes (A1 to F) based on their reaction to fire, smoke production, and flaming droplet production. This classification system helps determine the suitability of materials for various building applications. EN 13501 is divided into several parts, each covering a different type of fire performance classification:

EN 13501-1: Reaction to Fire
This part classifies how construction products (including floorings) contribute to the development of a fire.

Common classes: A1, A2, B, C, D, E, and F (A1 is non-combustible and F indicates that no performance has been determined). It also includes smoke production (s1, s2, s3) and flaming droplets/particles (d0, d1, d2).

EN 13501-2: Fire Resistance
This part classifies the fire resistance of building elements (e.g., walls, doors, floors, and beams) based on how long they maintain their integrity, insulation properties, and/or load-bearing capacity.

EN 13501-3: This part classifies the fire resistance of service installations (e.g., ducts and fire dampers).

EN 13501-4: This part classifies the fire resistance of smoke control systems.

Why It Matters:

Under the EU Construction Products Regulation (CPR), many construction products must bear a CE marking. This requires verified fire performance data according to EN 13501, which ensures that fire safety classifications are comparable and reliable across all European countries.

Meeting these fire classification requirements is critical in order for architects, builders, and material suppliers to ensure that their materials comply with building codes and can be legally placed on the market.

NETZSCH supports manufacturers and testing laboratories in achieving these certifications with its advanced fire testing instruments. Our devices, including cone calorimeters, SBI (single burning item) testers, and KBT (klein-brenner-test) systems, provide precise, standards-compliant measurements of reaction-to-fire and fire-resistance properties. These instruments enable our customers to generate accurate, repeatable data fully aligned with EN 13501 classification needs. This helps them bring safe, compliant products to market with confidence.

Understanding the fire behavior of polymer materials is essential for the safe design of electronic components and devices. Whether testing ignition resistance, oxygen demand, or heat release, NETZSCH fire testing instruments offer precise, standards-compliant solutions for a wide range of polymer applications.

The table below outlines which instrument is best suited for each type of fire test.
