Mechanical Sensitivity Drop-Weight Test)

The method involves subjecting the substance to the shock from a specified mass dropped from a specified height.

 

Drop-Weight Test Results

Test run	Drop Height	Mass	Results
1	40 cm	10 kg	Negative; no optical change in product apparent
2	40 cm	10 kg	Negative; no optical change in product apparent
3	40 cm	10 kg	Negative; no optical change in product apparent
4	40 cm	10 kg	Negative; no optical change in product apparent
5	40 cm	10 kg	Negative; no optical change in product apparent
6	40 cm	10 kg	Negative; no optical change in product apparent
Result			Six times negative

The test item is not sensitive to shock.

 

Mechanical Sensitivity Friction Mill)

The test item is a liquid. Testing was not necessary. This test is only applicable to solid materials.

 

Thermal Stability Steel Cartridge Test)

The method involves heating the substance in a steel tube, closed by orifice plates with differing diameters of hole, to determine whether the substance is liable to explode under conditions of intense heat and defined confinement.

 

Koenen Test Results

Nozzle Diameter	Reaction Initiation after	Results
2 mm	25 s	No fragments, cartridge unchanged
2 mm	24 s	No fragments, cartridge unchanged
2 mm	23 s	No fragments, cartridge unchanged
6 mm	24 s	No fragments, cartridge unchanged
6 mm	24 s	No fragments, cartridge unchanged
6 mm	24 s	No fragments, cartridge unchanged

The test item is not explosive when heated under defined confinement.

Interpretation of results:

GHS criteria not met

Conclusions:

The test item is not considered to have explosive properties.

Executive summary:

A study was conducted according to EC-Guideline 92/69/EWG A.14. The thermal sensitivity and the mechanical sensitivity to shock was investigated. The mechanical sensitivity to friction was not investigated as the test item is a liquid. No explosive properties were observed under the test conditions. Therefore, the item is not considered to have explosive properties.

Description of key information

Additional information

A study was conducted according to EC-Guideline 92/69/EWG A.14. The thermal sensitivity and the mechanical sensitivity to shock was investigated. The mechanical sensitivity to friction was not investigated as the test item is a liquid. No explosive properties were observed under the test conditions. Therefore, the item is not considered to have explosive properties.

Justification for classification or non-classification

Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
Based on the available data and taking into account the provisions laid down in Regulation (EC) No 1272/2008 (CLP), as amended for the eighteenth time in Regulation (EU) 2022/692, the test item does not have to be classified with respect to explosiveness.
