no

GLP compliance:

yes

Remarks:

temporary certificate

Parameter:

thermal sensitivity - Koenen test: diameter of the orifice plate

Remarks on result:

not thermal sensitive if heated under defined confinement

Parameter:

sensitiveness to impact: impact energy (J)

Thermal sensitivity

The tests conducted on plate with a 6 mm orifice gave the following results:

- a flame was generated after ca 144 seconds, accompanied by white smoke and strong odour

- vapours/air evolution from the orifice were observed after ca 190 seconds for a period of maximum 45 seconds

- after 30 seconds no further phenomenon was observed

Tests performed using hole of 2 mm showed a similar behaviour observed in the case of orifice of 6 mm. The reactions start after ca 97 seconds, while the phase of vapours/air evolution was within 163 - 212 seconds.

None of the six assays performed resulted to be positive.

Mechanical sensitivity (shock)

No explosion (bursting into flame and/ or a report is equivalent to explosion) occured during none of the six assays performed.

The sample resulted to be not sensitive to shock.

Mechanical sensitivity (friction)

No explosion (crepitation and/or a report or bursting into flame are equivalent to explosion) occured during none of the six assays performed.

The sample resulted to be not sensitive to friction.

Interpretation of results:

non explosive

Conclusions:

The sample doesn't have any explosive properties.

Executive summary:

The test was conducted according to the EU method A.14. The substance results to be not sensitive to impact, to friction and to flame exposure. Based on the data obtained the test item does not show any explosive propreties.

Justification for classification or non-classification

According to the CLP Regulation (EC 1272/2008), 2.1 section, an explosive substance or mixture is a solid or liquid substance or mixture of substances which is in itself capable by chemical reaction of producing gas at such a temperature and pressure and at such a speed as to cause damage to the surroundings. Pyrotechnic substances are included even when they do not evolve gases.

Substances, mixtures and articles of this class are classified as explosive on the basis of the results obtained from the test performed according to the methods described in Part I of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria.

The test item does not show any explosive properties therefore, according to the CLP Regulation (EC n. 1272/2008) the test item is classified as NON explosive.
