Mixture 1:1 , by mass, of 65.3 % (w/w) aqueous nitric acid and cellulose:

 Test 1  5872 ms
 Test 2  6539 ms
 Test 3  5709 ms
 Test 4  4705 ms
 Test 5  6106 ms

Mean pressure rise time: 5786 ms

Mixture 1:1 , by mass, of the test sample and cellulose:

 Test 1 17150 ms (pressure of 2070 kPa exceeded)
 Test 2 12445 ms (pressure of 2070 kPa exceeded)
 Test 3 13236 ms (pressure of 2070 kPa exceeded)
 Test 4 12779 ms (pressure of 2070 kPa exceeded)
 Test 5 13370 ms (pressure of 2070 kPa exceeded)

Mean pressure rise time: 13796 ms

Interpretation of results:
GHS criteria not met
Conclusions:
A spontaneous ignition of the mixture sample/cellulose during preparing could not be observed. In all tests the pressure of 2070 kPa was exceeded.
The sample has not to be considered as an oxidizer.
Executive summary:

A spontaneous ignition of the mixture sample/cellulose during preparing could not be observed. In all tests the pressure of 2070 kPa was exceeded.

The sample has not to be considered as an oxidizer.
