Additional information

Justification for classification or non-classification

In the preliminary screening test no propagation of the flame over 100 mm was observed throughout the course of the test. Therefore the test substance 2,2'-Azobis (4 -methoxy-2,4 -dimethyl valeronitrile) is considered as not "highly flammable" (EU A.10) under test conditions, although the test substance burnt vigorously.
