Key value for chemical safety assessment

Flammability:

not classified

Additional information

In order to evaluate the flammability of the test substance, a study was conducted according to the method A.10 of EEC-Directive 92/69 EEC. The substance could not be ignited with a flame and coloured black in contact with the ignition source.

Justification for classification or non-classification

According to the CLP Regulation (EC 1272/2008) powdered, granular or pasty substances or mixtures (except powders of metals or metal alloys — see 2.7.2.2) shall be classified as readily combustible solids when the time of burning of one or more of the test runs, performed in accordance with the test method described in Part III, sub-section 33.2.1, of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, is less than 45 seconds or the rate of burning is more than 2.2 mm/s.

Since no combustion was observed during the flammability test period, the substance cannot be classified as flammable according to the CLP classification criteria.
