Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

Between 06 March and 13 March 2012

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Remarks:

Study conducted in compliance with agreed protocols, with no or minor deviations from standard test guidelines and/or minor methodological deficiencies, which do not affect the quality of the relevant results. The study report was conclusive, done to a valid guideline and the study was conducted under GLP conditions.

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Deviations:

no

GLP compliance:

yes (incl. QA statement)

Specific details on test material used for the study:

White solid, batch# 9311205/008, purity 93%

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

Remarks:

The pile ignited with a small yellow flame which self-istinguished after 61 seconds without propagating combustion.

Results

Preliminary screening test

The pile ignited with a small yellow flame which self-extinguished after 61 seconds without propagating combustion.

The result of the preliminary screening test obviated the need to perform the main test.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The test item has been determined to be not highly flammable as it failed to propagate combustion along 200 mm within 4 minutes, in the preliminary screening test.

Executive summary:

INTRODUCTION AND PURPOSE

The purpose of this study is to evaluate the flammability (solids) and relative self-ignition temperature for solids of the test item.

The flammability (solids) was determined by measuring the burning rate of test item prepared as a pile of set dimensions. Testing was conducted using a procedure designed to be compatible with Method A10 Flammability (Solids) of Commission Regulation (EC) No 440/2008 of 30 May 2008.

RESULTS

Preliminary screening test

The pile ignited with a small yellow flame which self-extinguished after 61 seconds without propagating combustion.

 

The result of the preliminary screening test obviated the need to perform the main test.

CONCLUSION

The test item has been determined to be not highly flammable as it failed to propagate combustion along 200 mm within 4 minutes, in the preliminary screening test.

Description of key information

The test item has been determined to be not highly flammable as it failed to propagate combustion along 200 mm within 4 minutes, in the preliminary screening test. Furthermore, the substance is stable in air for prolonged period, not being considered as pyrophoric and also does not react with water, liberating flammable gases.

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

Based on outcome of a test the substance has been determined to be not highly flammable as it failed to propagate combustion along 200 mm within 4 minutes, in the preliminary screening test. Furthermore, the substance is stable in air for prolonged period, not being considered as pyrophoric and also does not react with water, liberating flammable gases. In conclusion, the substance is not classified for flammability according to CLP (Regulation EU 1272/2008).
