Interpretation of results:
GHS criteria not met
Conclusions:
According to EU Method A.17, Everzol Red CDN Crude is a non-oxidizing compound. Therefore, Everzol Red CDN Crude did not met GHS criteria.
Executive summary:

This test using the procedures outlined in the SNCL Study Plan for IA09-03 and EU Method A.17. In Preliminary test, the reference substance/ cellulose mixture burned for 112 seconds and Everzol Red CDN Crude did not burn. It is then necessary to complete the full train test. In Train test, the maximum burning rate of Barium Nitrate/cellulose mixture was found to be 0.34 mm/sec as a mixture with 60% barium nitrate by weight. Burning was not observed in any Everzol Red CDN Crude/cellulose mixture. Therefore, it is concluded that Everzol Red CDN Crude is a non-oxidizing compound.

Description of key information

Everzol Red CDN Crude is a non-oxidizing compound (EU Method A.17).
