Interpretation of results:
GHS criteria not met
Conclusions:
According to EU A.14 test method, CJ302 was not considered to present a danger of explosion.
Executive summary:

The explosive properties of CJ302 was determined according to EC REGULATION No 440/2008 Annex A.14 explosive properties. CJ302 does not present a danger of explosionin the thermal sensitivity (effect of a flame) test and mechanical sensitivity (shock and friction) test. Therefore, CJ302 was not considered to present a danger of explosion.

Description of key information

CJ302 was not considered to present a danger of explosion (EC A.14).

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

CJ302 does not present a danger of explosionin the thermal sensitivity (effect of a flame) test and mechanical sensitivity (shock and friction) test. Therefore, CJ302 was not considered to present a danger of explosion.
