Interpretation of results:
GHS criteria not met
Conclusions:
Test item and cellulose both mixture (4:1 and 1:1 ratio) showed as not ignited and burned. The oxidizing properties of CR SR94 was assessed and classified under Not Division 5.1 category.
Executive summary:

This study was performed as per UN Test O.1 guideline. The Oxidizing Properties of the test item was determined by using test item and cellulose powder mixture in the ration of 4:1 and 1:1 by weight basis. Test item and cellulose both mixture (4:1 and 1:1 ratio) showed as not ignited and burned. The oxidizing properties of CR SR94 was assessed and classified under Not Division 5.1 category.

Description of key information

Test item and cellulose both mixture (4:1 and 1:1 ratio) showed as not ignited and burned. The oxidizing properties of CR SR94 was assessed not classified.
