Key value for chemical safety assessment

Flammability:

not classified

Additional information

1. Flammability: In accordance with REACH Annex XI this study is scientifically unjustified. The flammability of liquids is determined on basis of their flashpoint. However the flammability was also analyzed for the solid form of Direct Yellow 86. The solid substance did not propagate burning of a 200 mm length of the strip in less than four minutes, therefore it is expected to be non flammable.

2. Pyrophoric properties: Testing of the substance for pyrophoric properties appears scientifically unjustified as the substance is market as aqueous suspension. As pyrophoric properties are only relevant for solids this study is omitted. The substance has no pyrophoric properties.

3. Contact with water: As the substance is market as aqueous solution and experience shows that there is no emission of flammable gases in contact with water the study is omitted. The substance has no potential to emit flammable gases in contact with water.

4. Self-heating: The study does not need to be conducted as Direct Yellow 86 is produced and market as liquid. The substance has no self-heating properties.

Justification for classification or non-classification

Direct Yellow 86 is a non-flammable liquid, is not flammable in contact with water, does not exhibit pyrophoric or self-heating properties. Based on the available information Direct Yellow 86 is not classified for physical hazards according to Regulation (EC) No 1272/2008 (CLP).
