NF P 92-503: M classification combustion test

NF P 92-503: M classification combustion test

NF P 92-503: Electrical burner test used for flexible materials thickness no more than 5mm

A specimen in placed in a specimen holder at 30° above a radiator which gives out heat(30kW/m²). A small butane flame is applied directly to the fabric surface.  The following aspects are recorded:  

- duration of the flame

- production of burning droplets

- length/width of the damaged specimen

If specific, unusual, specimen behaviour is observed additional supplementary tests may be required.

M Classification: M0-M4(M0、M1、M2、M3、M4)

Other Standard

NF P 92-501: Building materials- Reaction to fire tests, radiation test used for rigid material or flexible materials thickness more than 5mm.

NF P 92-503: Electrical burner test used for flexible materials thickness no more than 5mm

NF P 92-504: speed of spread of flame test used for the materials which are not intended to be glued on a rigid substrate.

NF P 92-505: Dripping test with electrical radiator, used for melting materials.
