BAM fall hammer test

No signs of ignition or explosion were observed with the negative reference substance.

In none of the 6 tests any sign of ignition or explosion was seen with the test substance. There were no flames, no sparks, no soot and no bang.

BAM friction test

There were no signs of an ignition or explosion, no flames, no sparks and no crepitating with the negative reference substance.

In none of the 6 tests any sign of ignition or explosion was seen with the test substance. There were no flames, no sparks and no crepitating.

Interpretation of results:
GHS criteria not met
Conclusions:
The test substance is not classified as explosive.
Executive summary:

The possible explosive properties of the test substance were determined according to EC-methods, using:

- The BAM fall hammer test which is a test for mechanical sensitivity to shock.

- The KOENEN steel tube test which is a test for thermal sensitivity.

- The BAM friction test which is a test for mechanical sensitivity with respect to friction.

No positive results to shock, friction and thermal stress were detected.

The test substance is not classified as explosive.
