Description of key information

non flammable, EU Method A.10 and A.12, Mclean 2012

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

A flammability test was performed in accordance with EU Method A.10 and under GLP conditions to ascertain the flammable properties of the test material. An initial preliminary test showed that the test material did not ignite during direct contact with the hot flame from a gas burner and instead melted in the presence of the flame. A full test test was therefore considered unnecessary and the test material is considered to be non flammable.

 

A flammability (contact with water) test was performed in accordance with EU Method A.12 and under GLP conditions to determine the flammable properties of the test material when in contact with water. This test concluded that the test material is not considered to be flammable when in contact with water.

 

In accordance with section 1.5 of REACH Regulation (EC) No. 1907/2006, Annex XI, the study does not need to be performed based on assessment of the chemical structure pyrophoric proerties are not to be expected and this is supported by experience in handling and use for hte substance. According to ECHA Guidance on Information Requirements and Chemical Safety Assessment (Chapter R. 7 a: Endpoint Specific Guidance, R. 7.1.10.4, May 2008), pyrophophoricity testing is scientifically unjustified.

Justification for classification or non-classification

The substance has been classified as a non-flammable solid using classification criteria under EU Directive 67/548/EEC.

The substance has been classified as a non-flammable solid using classification criteria under Regulation (EC) No 1272/2008.
