Method:

other: UN Test 3 (a) (iv): 30 kg Fallhammer test

Parameter:

other: drop height (no propagation)

Value:

4

Result:

negative, no propagation of detonation

Remarks:

>= 4 m

Test series:

UN Test series 3

Method:

other: UN Test 3 (a) (iv): 30 kg Fallhammer test

Parameter:

other: drop height (no reaction)

Value:

2.25

Result:

other: no reaction

Interpretation of results:

GHS criteria not met

Executive summary:

The substance was tested for sensitiveness to drop-weight impact, according to UN 30 kg fallhammer test.

The drop-weight height without propagation was >= 4 m, therefore the result is considered negative.

Type of information:

experimental study

Adequacy of study:

key study

Study period:

1985

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

test procedure in accordance with national standard methods with acceptable restrictions

Qualifier:

according to guideline

Guideline:

other: NFT 70-503

Qualifier:

equivalent or similar to guideline

Guideline:

UN Manual of Tests and Criteria: Part I: Classification procedures, test methods and criteria relating to explosives of Class 1

GLP compliance:

no

Test series:

UN Test series 3

Method:

UN Test 3 (b) (i): BAM friction apparatus

Parameter:

limiting load (N)

Value:

353

Result:

other: inconclusive, > 353 N

Remarks:

Julius Peters friction apparatus

Interpretation of results:

study cannot be used for classification

Executive summary:

The substance was tested for sensitiveness to friction, according to NFT 70-503, similar to BAM apparatus.

The maximum load tested was 353 N, i.e. below the UN threshold of 360 N, therefore the negative result is not sufficient for purpose of classification procedure according to CLP.

In the two assays conducted (loading length 20 cm), the substance did not burn or melt, during the 10 min period of ignition.

Executive summary:

The substance was tested for deflagration in open air in trough, according to NFT 70-507.

No burning or melting was observed upon heating.

Description of key information

The substance is classified as an explosive, with mass explosion hazard.

However, it has low sensitivity to temperature and shock.

Key value for chemical safety assessment

Explosiveness:

explosive

Additional information

Experimental data is available with regard to impact sensitivity, friction, priming the detonation, and deflagration, and is considered sufficient for classification purpose.

Supporting literature provides additional information on thermal properties and performances of the explosive.

Justification for classification or non-classification

Classification was performed according to testing protocol and decision tree described in French Arrêté and Circulaire of 20/04/2007, relating to risk assessment and prevention of accidents in pyrotechnique plants.

Considering the substance was assigned to the worst-case division 1.1, no new testing was deemed necessary.
