Interpretation of results:
GHS criteria not met
Conclusions:
According to UN Manual of Tests and Criteria: Test O.1, Everzol SR98 is a non-oxidizing solid. Therefore, Everzol SR98 did not met GHS criteria.
Executive summary:

This test using the procedures outlined in the ZRICI Study Plan for PCF2019-045-06 and UN Manual of Tests and Criteria: Test O.1. The mean burning times of Tested-mixture I and II were both greater than that of Standard-mixture I. Base on the above results, Everzol SR98 was confirmed a non-oxidizing solid.

Description of key information

Everzol SR98 is not considered as an oxidizing substance (UN Manual of Tests and Criteria: Test O.1).

Key value for chemical safety assessment

Oxidising properties:
non oxidising

Additional information

The mean burning times of Tested-mixture I (Everzol SR98 : Fibrous cellulose = 1 : 1) and Tested-mixture II (Everzol SR98: Fibrous cellulose = 4 : 1) were both greater than that of Standard-mixture I (Potassium bromate : Fibrous cellulose = 3 : 7). Base on the above results, Everzol SR98 was confirmed a non-oxidizing solid.
