Key result

Test procedure:

burning rate test: preliminary screening test

Burning time:

> 120 s

Moisture (wt %):

2.54

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 screening test a burning time of > 120 sec. (2 min.) was recorded for the flame propagation over 200 mm. Thus the preliminary screening test was negative and no further testing was required.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The test item is not to be regarded as readily combustible solid, i.e. flammable solid.

Executive summary:

The flammability of the test item was determined in a study performed in accordance with UN N.1 method. It was observed that the 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. Thus the preliminary screening test was negative and no further testing was required.

Therefore, the test item is not to be regarded as readily combustible solid, i.e. flammable solid.

Description of key information

The flammability of the test item was determined in a study performed in accordance with UN N.1 method. No propagation of combustion of the test item along 200 mm length of the pile within 2 minutes was observed in the preliminary screening test. According to the guidelines, performance of the burning rate test is not required. Based on the results obtained, the test item is considered ‘not flammable’.

In additional UN.4 was performed since the melting range was close to these 160°C and since decomposition (gas formation) was observed above the melting point. The test item is not to be regarded as a self-heating substance. 

Key value for chemical safety assessment

Flammability:

not classified

Additional information

Testing was conducted according to a scientifically valid and accepted method (UN Test N.1) without deviations. The study is considered as reliable (Klimisch 1) and is selected as a key study for the endpoint.

Justification for classification or non-classification

In the preliminary screening test of the UN.1 test, a burning time of > 120 sec. (2 min.) was recorded for the flame propagation over 200 mm. Based on this result, the test item is not to be regarded as readily combustible solid, i.e. flammable solid.

The test item does not meet the CLP criteria for classification.
