UN Test 2 (b): Koenen test

Parameter:

limiting diameter (mm)

Value:

2

Result:

result is considered "-" (negative)

Remarks on result:

other: No explosions occurred and each test was suspended after a total heating period of 5 minutes

Results mechanical sensitivity (shock)

The six tests performed by dropping a 10 kg weight from a height of 0.4 m did not result in ignition or explosion on impact.

 

Results mechanical sensitivity (friction)

The six tests are carried out with a loading force of 360 newtons did results in signs of decomposition of the test substance, as indicated by black marks on the porcelain plate and pin after each test.

 

Method thermal sensitivity

No explosions occurred and each test was suspended after a total heating period of 5 minutes. During testing, after a time t1 (time elapsed from ignition of burners to the first noticeable reaction of the test substance) and lasting for a time t2 ( time elapsed from t1 to the end of the reaction), the sample vented through the orifice and burned with a flame.

Interpretation of results:

GHS criteria not met

Conclusions:

The test substance does not have explosive properties.

Executive summary:

The explosive properties of the test substance were determined by assessing mechanical sensitivity with the BAM Fall Hammer and BAM Friction Apparatus. Thermal sensitivity was assessed using the Koenen steel tube apparatus. The study was performed according to EU Method A.14 following GLP principles. The test substance was determined not to be thermal and mechanical (both shock and friction) sensitivity. Therefore, the test substance is not classified as an explosive.

Description of key information

Explosiveness: The test substance did not explode when exposed to heat, mechanical shock or friction, EC Test A.14, BAM Falling Hammer, BAM Friction apparatus, Koenen Steel Tube apparatus, Jackson 2008

Key value for chemical safety assessment

Explosiveness:

non explosive

Justification for classification or non-classification

Based on the available information, classification on explosiveness is not warranted in accordance with EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation No. (EC) 1272/2008.
