Adequacy of study:

key study

Study period:

December 15, 2017

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

test procedure in accordance with generally accepted scientific standards and described in sufficient detail

Qualifier:

according to guideline

Guideline:

UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)

Deviations:

no

GLP compliance:

no

Test procedure:

burning rate test: preliminary screening test

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

In the preliminary test the test item did not burn over a distance of 200 mm. The test item did not ignite at room temperature, the test item melted.

Interpretation of results:

other: not classified, according to the CLP Regulation (EC) No 1272/2008

Conclusions:

Not classified, according to the CLP Regulation (EC) No 1272/2008

Executive summary:

The flammability potential of the test item was investigated

It was tested whether a test item should be classified as a highly flammable solid, readily combustible solid and flammable solid with respect to UN Transport Regulation (Class 4, Division 4.1) and GHS / CLP Regulation EC 1272/2008, respectively.

The test item was filled loosely into the mould. Then, the mould was closed and the test item was compacted. After that, the mould was opened on the top and a ceramic plate was laid on the top of the mould. The mould and the plate were then turned around by 180 °. The mould was removed so that train of the test item lay on the ceramic plate with the shape of the inner mould. The pile of the test item was placed across the exhausting direction of the fume hood.

The main test has to be performed in case the test item burns over a distance of 200 mm within 2 minutes (20 minutes for metal dusts).

In the preliminary test the test item did not burn over a distance of 200 mm. The test item did not ignite at room temperature, the test item melted. Thus, the performance of the main test was not necessary.

Conclusion

Not classified, according to the CLP Regulation (EC) No 1272/2008

Justification for classification or non-classification

According to the CLP Regulation (EC) No 1272/2008, flammable solids are classified according to their burning rate (or burning time) obtained in six test runs. Furthermore, a flammable solid means a solid which is readily combustible, or may cause or contribute to fire through friction. Readily combustible solids are powdered, granular, or pasty substances or mixtures which are dangerous if they can be easily ignited by brief contact with an ignition source, such as a burning match, and if the flame spreads rapidly.

In the preliminary test the test item did not burn over a distance of 200 mm. The test item did not ignite at room temperature; the test item melted.

In conclusion, the substance does not meet the criteria to be classified as flammable, according to the CLP Regulation (EC) No 1272/02008.
