Description of key information
Non-flammable, EU Method A.10, Butler & O'Connor (2009)
Based on the chemical structure of the substance, pyrophoric properties and flammability in contact with water are not expected.
Key value for chemical safety assessment
- Flammability:
- non flammable
Additional information
Flammability, solids
The flammability (solids) of the test substance was investigated in a study which was conducted in accordance with the standardised guideline EU Method A.10.
A preliminary screening test was conducted during which a mould (250 x 20 x 10 mm) was loosely filled with test substance. 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 for a maximum of two minutes. If combustion occurred, the time taken to propagate 200 mm was recorded.
During the preliminary screening test, the pile failed to ignite during the two minutes that the Bunsen flame was applied. The negative results of the screening test negated the need to perform the main test.
Therefore, under the conditions of the study the test substance was concluded to be non-flammable.Since the study report was conclusive and done to a valid guideline the study has been assigned a reliability score of 1 in line with the criteria of Klimisch (1997).
Flammability, pyrophoric properties
In accordance with section 1.5 of REACH Annex XI, the study does not need to be performed as based on chemical structure pyrophoric properties are not to be expected.
Flammability, contact with water
In accordance with section 1.5 of REACH Annex XI, the study does not need to be performed as based on chemical structure water reactivity is not to be expected.
Justification for classification or non-classification
In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No. 1272/2008, the substance does not require classification with respect to flammability.
In accordance with the criteria for classification as defined in Annex VI, Directive 67/548/EEC (DSD), the substance does not require classification with respect to flammability.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
