Key result

Test procedure:

burning rate test: preliminary screening test

Remarks:

flame over 100 mm

Remarks on result:

not determinable

RESULT

The test substance could not be ignited with a flame. The test substance melted, coloured yellow/brown and emitted sparks and grey smoke in contact with the ignition source.

Interpretation of results:

GHS criteria not met

Conclusions:

The test substance could not be ignited with a flame. In conclusion, the test substance is not "highly flammable".

Executive summary:

A test was performed in accordance with EC Method A.10 and in compliance with GLP. A preliminary test carried out using a gas burner showed that test substance could not be ignited (it melted), therefore the main test was unnecessary. The test substance melted, coloured yellow/brown and emitted sparks and grey smoke when in contact with the ignition source. Hence, it was concluded that the test substance is not "highly flammable".

Description of key information

Negative test results were obtained in flammability studies as the substance could not be ignited (it melted) in the preliminary test, hence the substance is not classified as highly flammable in terms of its burning characteristics, EU Method A.10, van Helvoirt 1994.

As the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and is known to be soluble in water to form a stable mixture no studies are needed with respect to "pyropholic solid” features and "Substance/ mixtures with in contact with water emits flammable gases", respectively.

Also no study is needed to determine self heating characteristics as the substance is completely molten at 160 °C and the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days).

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

Based on the available information, the test substance is not classified as flammable solid, self heating substance, pyrophoric solid or substance which in contact with water emits flammable gases in accordance with EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation No. (EC) 1272/2008.
