Conclusions:
CuGUN substance does not present an explosion risk when submitted to the effect of a flame (thermal sensitivity), or to shock or friction (sensitivity to mechanical stimuli).
Executive summary:

The EU A14 test method provides a scheme of testing to determine whether a solid or a pasty substance presents an explosion risk when submitted to the effect of a flame (thermal sensitivity), or to shock or friction (sensitivity to mechanical stimuli), and whether a liquid substance presents a danger of explosion when submitted to the effect of a flame or shock.

methods:

The method comprises three parts:

a)   a test of thermal sensitivity (with apparatus of Koenen test),

b)   a test of mechanical sensitivity with respect to shock (40J),

c)   a test of mechanical sensitivity with respect to friction (360 N).

The method yields data to assess the likelihood of initiating an explosion by means of certain common stimuli. The method is not intended to ascertain whether a substance is capable of exploding under any conditions.

results:

The test results for the CuGUN are negative for the tests of thermal sensitivity, of mechanical sensitivity with respect to shock and to friction.The substance CuGUN does not present an explosion risk when submitted to the effect of a flame (thermal sensitivity), or to shock or friction (sensitivity to mechanical stimuli).

conclusion:

By test results, we conclude that substance CuGUN does not present danger of explosion when submitted to the effect of a flame (thermal sensitivity), or to shock or friction (sensitivity to mechanical stimuli).

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

By test results, we conclude that substance CuGUN does not present danger of explosion when submitted to the effect of a flame (thermal sensitivity), or to shock or friction (sensitivity to mechanical stimuli).

Justification for classification or non-classification

According to 1272/2008 (CLP) regulation, as CuGUN does not present danger of explosion (thermal sensitivity or sensitivity to mechanical stimuli), CuGUN is a non explosive substance.
