A material is classified M1 if the tests with the electrical burner (NF P 92-503) results in:

• No inflammation remaining longer than 5 seconds after removing the flame

• No points of ignition with flame propagation higher than 25 cm above the lower edge of

the probe

• No drops of flaming material (test for thermo fusible materials NF P 92-505 

to be passed)

If the material pierces without inflammation or with inflammation which subsides within 5
seconds, the persistency test (NF P 92-504) results in no flame persistency at all and no
burning material drops.

A material is classified M2 if it does not fall into category M1 because  

• Inflammation persists longer than 5 seconds after removing of the flame

• Destruction of the material deeper than 35 cm from the lower edge of the probe is

observed 

• No drops of flaming material (test for thermo fusible materials NF P 92-505 

to be passed)

If the material pierces without inflammation or with inflammation, which subsides within 5
seconds, the persistency test (NF P 92-504) results in flame persisting for no longer than 5
seconds without propagation and no burning material drops.

For exhibition graphics there are sometimes requests for flammability ratings of products. The main standards used
are the French “M” ratings, German “B” ratings (B1 often considered similar but not higher than M1) and the US
NFPA standards. There is no common international standard at this time.

Ink and media are sensitive to environmental conditions. It is important that supplies are kept in a controlled area
for the best image quality and operation when used in the printer.
