burning rate test: preliminary screening test

Remarks on result:

not determinable

Remarks:

After the flame application to one end of the pile the substance immediately melted and a black molten mass was visible but no ignition of the substance could be observed.

Any other information on results incl. tables

1 Drying loss

Due to the low melting point of the substance the drying loss was determined at 60°C using the Mettler Moisture Analyzer HB 43-S. The result was a value of 0.13 %.

2 Preliminary test

The substance was formed into an unbroken strip about 250mm long by 20 mm wide by 10 mm high on a non-combustible and non-porous plate with low thermal conductivity.

After the flame application to one end of the pile the substance immediately melted and a black molten mass was visible but no ignition of the substance could be observed.

According to the test guideline execution of the main test was not necessary.

Applicant's summary and conclusion

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The flammability was determined according to a scientifically valid method, i.e. EU method A.10 under GLP, in a well-documented study, hence, the following result for the test material can be considered as reliable:
After the flame application in the pre-liminary test to one end of the pile the substance immediately melted and a black molten mass was visible but no ignition of the substance could be observed. According to the test guideline execution of the main test was not necessary and the test item can be considered as not highly flammable.
No observations were made which might cause doubts concerning the validity of the study outcome.

Executive summary:

The flammability of the test item was determined following EU-Method A.10 under GLP.

In the preliminary screening test the test item in the delivery form is made into pile of 250 mm length on a non-combustible and non-porous plate with low thermal conductivity and then an attempt is made to ignite the sample. When in this preliminary test the item cannot be ignited or if the propagation time for the 200 mm distance is longer than 4 minutes (in case of metal powders longer than 40 minutes) the performance of the main test is not required. In such cases the test item is assessed to be not highly flammable. This was the case here, after the flame application to one end of the pile the substance immediately melted and a black molten mass was visible but no ignition of the substance could be observed. According to the test guideline execution of the main test was not necessary and the test item can be considered as not highly flammable.
