Interpretation of results:

GHS criteria not met

Conclusions:

According to UN Manual of Tests and Criteria: Test O01, CR SB87 is not considered as an oxidizing substance. Therefore, CR SB87 was not met GHS criteria.

Executive summary:

This test using the procedures outlined in the ZCTC Study Plan for PCF2017-004-5 and UN Manual of Tests and Criteria: Test O01. Both of Tested-mixture I and Tested-mixture II did not be ignited and burned. Base on the above results, CR SB87 was confirmed a non-oxidizing solid.

Description of key information

CR SB87 is not considered as an oxidizing substance (UN Manual of Tests and Criteria: Test O01).

Key value for chemical safety assessment

Oxidising properties:

non oxidising

Additional information

Both of Tested-mixture I (CR SB87 : Fibrous cellulose = 1 : 1) and Tested-mixture II (CR SB87 : Fibrous cellulose = 4 : 1) did not be ignited and burned. Base on the above results, CR SB87 was confirmed a non-oxidizing solid.
