After 60 seconds, mean heating rate was 151.2°C

Based on results obtained at 4.5 LPM, mean heating rate of DIBUTYL PHTHALATE was achieved to be 135°C/min to 285°C/min range.

12		No	No
8.0		No	No
5.0		No	No
3.0		No	No
2.5		No	No
2.0		No	No
1.5		No	No
1.0		No	No

Result: Test item showed that no violent effect on heating under confinment condition.

Interpretation of results:

GHS criteria not met

Conclusions:

The explosive properties of CR SR94 was determined and concluded as Non Explosive.

Executive summary:

This study was performed as per UN Test 1(b): Koenen Test guideine. The Explosiveness of the test item was determined using Koenen Tube. There is no violent effect on heating under confinement conditions. The explosive results showed that negative and limiting diameter was recorded and reported as less than 1.0 mm diameter. Therefore, the explosive properties of CR SR94 was determined and concluded as Non Explosive.
