Key result

Test procedure:

other: burning index according to VDI 2263

Burning time:

> 120 s

Remarks on result:

other: burning index BZ 5

Remarks:

burning with flame or spark generation

The product showed burning with fire spreading when an ignition source (flame or hot wire, 2 min) was applied at ambient temperature. The product did not melt.

The combustion behaviour of the product at ambient temperature is characterized by the burning index BZ 5 (burning with flame or spark generation) .

Due to the fact that propagation of the combustion was observed the burning rate needed to be determined.

In the preliminary test the flame extinguished reproducibly after a burning distance of max 6cm, which has to be assessed as exceedance of the limit of 120 s. Therefore, the main test did not need to be performed.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The substance has not to be classified as flammable solid according to Regulation (EC) No 1272/2008.

Key value for chemical safety assessment

Flammability:

not classified
