Description of key information

The substance is not flammable (no solid).

Key value for chemical safety assessment

non flammable

Additional information

Burning rate, solid:

According to REACH legislation, Annex VII, column II flammability does not need to be conducted since the substance is a liquid. Flammability for liquids is expressed as flash point.

Contact with water:

'Polyether V 531' did not ignite spontaneously with water and did not liberate gases in hazardous amounts when tested according to EC Test Procedure A 12. The applied testing method is identical to the testing method with UN -Manual ‘Recommendations on the Transport of Dangerous Goods – Manual of Tests and Criteria’ (fourth revised edition) Test N.5 (UN 33.4.14).

With application of EC-Guideline 1272/2008 (‘Globally Harmonized System of Classification and Labelling of Chemicals - GHS‘ Annex 1 chapter 2.12 the criteria for classification 'Polyether V 531’ as ‘substance which in contact with water emit flammable gases’ are not fulfilled (Currenta, 2009)..

Pyrophoric properties:

The molecular structure of the substance does not contain functional groups that might lead to pyrophoricity. Therefore it is considered justified to omit the study.

Justification for classification or non-classification
