Results

Mechanical shock sensitivity

None of the six single tests using an impact energy of 40 J showed any sparking or exploding. Therefore the series

using an impact energy of 7.5 J was not necessary. No impact sensitivity of the test item was observed.

Mechanical friction sensitivity

None of six single tests with a friction force of 360 N showed any visible or audible explosion or crackling, or

sparking. Therefore the series with a friction force of 120 N was not necessary. No friction sensitivity of the test item

was observed.

Thermal sensitivity

The steel tubes were filled with 22.5 g of the substance.

Using the 6 mm orifice after 48 s – 51 s the start of a reaction was observed in the single tests

(orange/greenish coloured flame of about 0.5 m height above the tube). The reaction lasted 29 s – 30 s. No further

observation was made until the burners were turned off after 5 minutes. After cooling down it was observed that all

the tubes were unchanged.

Using the 2 mm orifice after 48 s – 52 s the start of a reaction was observed in the single tests (noisy ejection of

burning test substance with an orange/greenish coloured flame of about 0.7 m height above the tube). The reaction

lasted 30 s – 33 s. No further observation was made until the burners were turned off after 5 minutes. After cooling

down it was observed that all tubes were unchanged.

According to the assessment criteria no thermal sensitivity was detected.

Interpretation of results:

GHS criteria not met

Conclusions:

As the sample was neither mechanical sensitive to shock or friction nor thermally sensitive, according to the criteria of EEC test method A.14 it is not representing an explosive hazard and has not to be considered to present a danger of explosion.

Executive summary:

As the Guanidine nitrate sample was neither mechanical sensitive to shock or friction nor thermally sensitive, according to the criteria of EEC test method A.14 it is not representing an explosive hazard and has not to be considered to present a danger of explosion.

Description of key information

Guanidine Nitrate is not explosive.

Key value for chemical safety assessment

Explosiveness:

non explosive

Additional information

As Guanidine Nitrate was neither mechanical sensitive to shock or friction nor thermally sensitive, according to the criteria of EEC test method A.14 it is not representing an explosive hazard and has not to be considered to present a danger of explosion.

Justification for classification or non-classification

Non explosive according to tests: neither mechanical sensitive to shock or friction nor thermally sensitive (EEC A.14).
