Multi-purpose flammability tester

FlexiBurn is our vertical flammability tester. You can use FlexiBurn for testing ease of ignition and the flame spread properties of apparel, curtains, drapes, nightwear, toys, protective clothing, technical fabrics, building and other materials. For each material, there are applicable British, European or ISO standards, which set out the precise conditions for these very critical tests.


Designed With You In Mind



The position of the gas burner changes according to the standard, so we designed a robotic arm for precise positioning of the burner.



Virtually every method requires a different test frame – regardless of size and pin configuration, our frames are easily interchangeable.



To guide you through the complex world of flammability standards and test methods, we supply a pre-programmed Control Module for our flammability tester.


Curtains and Drapes

Large ignition source
FlexiBurn meets the requirements of BS EN 13772 for curtains and drapes, which evaluates flame spread. Flammability standards are constantly evolving, so we have future-proofed the instrument. In conjunction with FlexiBurn, we offer an optional Test Chamber, which also meets the stringent conditions dictated by standards, minimising health and safety risks.


What materials can you test with FlexiBurn?


FlexiBurn testing flammability of nightwear


FlexiBurn is used to test flame retardancy and the anti-flame properties of nightwear.


Flammability testing for childrens toys


FlexiBurn is specified to assure the safety of small toys and children’s playthings.


Flammability testing of curtains and drapes


FlexiBurn is employed to evaluate the flame resistance of curtains and drapes.


FlexiBurn Test Chamber

Optional purpose-designed chamber
Flammability testing should not be conducted in the open, because of the flames, smoke and gas, generated by burning materials. The standards also specify a minimum volume of 4m3 and an air speed of less than 0.2m /sec. Although a room can be adapted to meet these requirements, it is safer and easier to use our purpose-designed Test Chamber.
