Interpretation of results:
GHS criteria not met
Conclusions:
According to UN Manual of Tests and Criteria: Test O.1, I850 is not considered as an oxidizing substance. Therefore, I850 was not met GHS criteria.
Executive summary:

The oxidizing properties of I850 was determined according to UN Manual of Tests and Criteria: Test O01.Mean burning time of sample-to-cellulose ratio 4:1 and 1:1 are all more than mean burning time 104s of reference substances of potass bromate and cellulose ratio according to the quality of 3:7. Base on the above results, I850 was not classified as oxidizer.

Description of key information

I850 was not classified as oxidizer (UN Manual of Tests and Criteria: Test O.1).

 

Key value for chemical safety assessment

Oxidising properties:
non oxidising

Additional information

Mean burning time of sample-to-cellulose ratio 4:1 and 1:1 are all more than mean burning time 104s of reference substances of potass bromate and cellulose ratio according to the quality of 3:7. Base on the above results, I850 was not classified as oxidizer.
