Key result

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

Interpretation of results:

GHS criteria not met

Conclusions:

The test item is considered as a not readily combustible solid of Division 4.1.

Executive summary:

The flammability properties of test substance were assessed in a test according to Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria sixth revised edition; Test N.1: Test method for readily combustible solids (TOXI-COOP, 2016). In the preliminary test the test item could not be ignited. Based on the results of the preliminary test, no main test was performed. The test item is regarded as not readily combustible solid.

Description of key information

The test item is regarded as non flammable.

The substance has no pyrophoric properties and does not liberate flammable gases in contact with water.

The substance is not a self-heating substance or mixture.

Key value for chemical safety assessment

Flammability:

not classified

Additional information

The flammability properties of test substance were assessed in a test according to Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria sixth revised edition; Test N.1: Test method for readily combustible solids (TOXI-COOP, 2016). In the preliminary test the test item could not be ignited. Based on the results of the preliminary test, no main test was performed. The test item is regarded as not readily combustible solid.

Based on chemical structure pyrophoric properties and flammability in contact with water are not to be expected.

No self heating properties are predicted based on the low melting point of 116 °C (< 160 °C).

Justification for classification or non-classification

In accordance with Annex I, Section 2.1, Section 2.2, Section 2.3, Section 2.7, Section 2.9, Section 2.10 Section 2.11, Section 2.12 of Regulation (EC) No 1272/2008 and UN GHS Rev 7 (2017) the substance has not to be classified as readily combustible solid in class 4 Division 4.1, self-heating substance in Class 4 Division 4.2, substances which in contact with water emit flammable gases in Class 4 Division 4.3, pyrophoric solid in class 4 Division 4.2, flammable gases in class 2 or as aerosol in class 2.
