Results

Test No.              Apparent density/ kg/m3              Fragmentation length / cm       Witness plate perforated ?

-----------------------------------------------------------------------------------------------------------------------------------------------------------

1                            1239.0                                          40.0                                          Yes

According to the procedure for provisional acceptance of explosive substances in class 1 the question "does the substance propagate a detonation" is answered "yes".

According to the flow chart scheme for self-reactive substances and organic peroxides the same question is answered "yes".

The test was repeated with a polymethyl methacrylate spacer.

Test No.              Apparent density/ kg/m3              Fragmentation length /cm             Witness plate perforated ?

----------------------------------------------------------------------------------------------------------------------------------------------------------------

2                            1125.0                                          0.0                                                 No

On the basis of the result the question "is the substance sensitive to detonative shock" is answered "no".

Interpretation of results:
GHS criteria not met
Conclusions:
The test substance is not considered to exhibit a danger of explosion.
