Results and discussion

Flammable solids

Test procedure:

burning rate test: preliminary screening test

Burning time:

0 s

Remarks on result:

substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period

Any other information on results incl. tables

The product showed no reaction when an ignition source (flame or hot wire) was applied at ambient temperature. A propagation of the combustion was not observed. The product melted. At an elevated temperature of 100 °C the same behaviour was observed.

The combustion behaviour of the product at ambient temperature is characterized by the burning index BZ 1 (no ignition).

The combustion behaviour of the product at elevated temperature (100 °C) is characterized by the burning index BZ 1 (no ignition).

Due to the fact that no propagation of the combustion was observed the burning rate had not to be determined.

Applicant's summary and conclusion

Interpretation of results:

GHS criteria not met

Conclusions:

The product showed no reaction when an ignition source (flame or hot wire) was applied at ambient temperature. A propagation of the combustion was not observed. The product melted. At an elevated temperature of 100 °C the same behaviour was observed.
The combustion behaviour of the product at ambient temperature is characterized by the burning index BZ 1 (no ignition).
The combustion behaviour of the product at elevated temperature (100 °C) is characterized by the burning index BZ 1 (no ignition).
Due to the fact that no propagation of the combustion was observed the burning rate had not to be determined.

UN transport regulation: The substance does not have to be classified as a "readily combustible solid", class 4.1, of the transport regulations.
EU-GHS/CLP: The substance does not have to be classified as a "flammable solid".
Regulation (EG) 440/2008 (test methods for REACH): The substance does not have to be classified as a "highly flammable solid".

Executive summary:

This study is performed compliance with Council Regulation (EC) No 440/2008 of 30 May 2008 laying down test methods pursuant to Regulation (EC) No 1907/2006 of the European Parliament and of the Council on the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) Annex, Part A, Methods for the determination of physico-chemical properties, A.10 "Flammability (solids)", EEC Publication No. L142 and the Principles of Good Laboratory Practice (GLP) and reported with a valid GLP certificate.

 

The flammability of the test substance was investigated in two parallel independent test runs, which were both negative.

The test item is not flammable in the conditions of this test.
