Reference

Endpoint:

oxidising solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2015

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.17 (Oxidising Properties (Solids))

Version / remarks:

published in O.J. L 142, 2008

Interpretation of results:

GHS criteria not met

Conclusions:

On basis of the result obtained from trial test, it is obvious that the maximum burning rate of the tested mixture is lower than maximum burning rate of the reference mixture of cellulose and barium nitrate. Thus test substance, Reactive Violet 1, shouldn´t be considered as a substance with oxidizing properties.

Executive summary:

The oxidizing properties of test substance, Reactive Violet 1, were determined. The procedure was performed according to the Method A.17 Oxidizing properties (Solids), Council Regulation (EC) No.440/2008, published in O.J. L 142, 2008. On basis of the result obtained from trial test, it is obvious that the maximum burning rate of the tested mixture is lower than maximum burning rate of the reference mixture of cellulose and barium nitrate. Thus test substance, Reactive Violet 1, shouldn´t be considered as a substance with oxidizing properties.

Key value for chemical safety assessment

Oxidising properties:

non oxidising

Justification for classification or non-classification

On basis of the result obtained from trial test, it is obvious that the maximum burning rate of the tested mixture is lower than maximum burning rate of the reference mixture of cellulose and barium nitrate. Thus test substance, Reactive Violet 1, shouldn´t be considered as a substance with oxidizing properties.
