Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The maximum burning rate of the test item in different mixtures was found to be lower than the maximum burning rate of the reference mixture in the Full Train Test. The test substance has no oxidizing properties, according to the test method.
Executive summary:

Introduction

This prediction was undertaken to predict the oxidizing properties of the test material. The procedure used was designed to be compatible with Method A17 Oxidising Properties (Solids) of Commission Regulation (EC) No 440/2008 of 30 May 2008.

Results & Conclusions

The maximum burning rate of the test item in different mixtures was found to be lower than the maximum burning rate of the reference mixture in the Full Train Test. The test substance has no oxidizing properties, according to the test method.
