Description of key information

The test material is not a flammable or readily combustible solid.

Key value for chemical safety assessment

non flammable

Additional information

The key study was conducted in line with GLP using a procedure designed to be compatible with Test N.1. of the United Nations Recommendations on the Transport of Dangerous Goods Manual of Tests and Criteria, 5th revised edition 2009 and Section 2.7 of Regulation (EC) No 1272/2008 of 16 December 2008 on Classification Labelling and Packaging of Substances and Mixtures.

It was assigned a reliability score of 1 in accordance with the criteria detailed by Klimisch (1997).

In a preliminary screening test, a mould was loosely filled with test material; a non-combustible, non-porous board was placed onto the mould which was then inverted. The mould was removed and an air-rich Bunsen burner flame applied to one end of the pile until ignition occurred; the time taken to propagate 200 mm was recorded.

The pile failed to ignite during the two minutes that the Bunsen flame was applied, obviating the need to perform the main test.

Under the conditions of this study, the test material is not a flammable or readily combustible solid.



In accordance with section 1 of REACH Annex XI, the studies to investigate the properties of pyrophoricity and flammability on contact with water (required in section 7.10 of Annex VII) are scientifically unjustified. Based upon the known chemical and physical properties of the substance, its chemical structure and experience in handling the substance, testing is predicted to produce negative results.

Justification for classification or non-classification

In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No. 1272/2008, the test material does not require classification for flammability.
