Description of key information

- not highly flammable upon ignition

- no pyrophoric properties

- does not liberate flammable gases on contact with water

Key value for chemical safety assessment

Additional information

The flammability was carried out by screening test "burning behaviour" according to Guideline VDI 2263,1990.

- Upon ignition the test substance was brief ignition followed by rapid extinction.

- Based on chemical structure and experience in handling and use of substance the pyrophoric properties and the flammability in contact with water are not to be expected.

Justification for classification or non-classification

- Upon ignition the test substance was brief ignition followed by rapid extinction.

- Based on chemical structure and experience in handling and use of substance the pyrophoric properties and the flammability in contact with water are not to be expected.

The theoretical assessments of pyrophoricity and flammability on contact with water are based on section R.7.1.10 of Guidance chapter R.7a of REACH Regulation (EC) No 1907/2006.

It can be concluded that the substance is not considered to be classified as a flammable material.

Further justification:

- The substance should not be classified as self-reactive substance as the heat of decomposition is greater than 300 J/g but the onset temperature is greater than 200 °C.

- The substance should not be classified as self-heating substance as the onset temperature is above 220 °C by the Grewer Oven test (VDI Guideline 2263, 1990).
