Interpretation of results:

GHS criteria not met

Conclusions:

The test item does not have oxidising properties.

Executive summary:

The oxidative properties of the test item were determined in a study performed according to Method A.17 of Commission Directive 92/69/EEC.

Description of key information

The test item is not oxidising based on the results of this test.

Key value for chemical safety assessment

Oxidising properties:

non oxidising

Justification for classification or non-classification

The oxidising properties of the test item were deduced using EU Test Method A.17 of Commission Directive 92/69/EEC. This test is only designed to indicate whether or not a substance has oxidising properties. Since the test item did not meet the criteria for classification as an oxidising solid under this test method, it is considered that it is also not classified as an oxidising solid under CLP (ref. Guidance on the Application of the CLP Criteria, Verson 4.1 - June 2015).
