Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

data from handbook or collection of data

Qualifier:

according to guideline

Guideline:

other: no guideline available (Publication data)

Parameter:

other: The parameter observed is friction or shock which provides a sudden supply of energy on the compound.

Remarks on result:

other: The violent decomposition of the peroxide may occur due to friction or shock, provides a sudden supply of energy leading to a localized temperature rise of the compound.

Interpretation of results:

study cannot be used for classification

Conclusions:

The violent decomposition of a peroxide may occur due to friction or shock, provides a sudden supply of energy leading to a localized temperature rise of the compound.

Specific details on test material used for the study:

SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: Na2O2 tamise- lot 17286-10
- Sampling test date: 16/10/2017


STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: RT
- Stability under test conditions: Yes

Test series:

UN Test series 1

Method:

UN Test 3 (a) (ii): BAM Fallhammer

Parameter:

limiting impact energy (J)

Result:

result is considered "-" (negative)

Remarks:

The test was negative, i.e. during none of the six 40 J tests an explosion was observed for the test sample.

Remarks on result:

no ignition, explosion, self-heating or visible decomposition

Test series:

UN Test series 2

Method:

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

Parameter:

limiting load (N)

Result:

result is considered "-" (negative)

Remarks:

The test was negative, i.e. during none of the six tests with the 360 N loading an explosion was observed for the test sample.

Remarks on result:

no ignition, explosion, self-heating or visible decomposition

Test series:

UN Test series 3

Method:

UN Test 1 (b): Koenen test

Parameter:

limiting diameter (mm)

Result:

result is considered "-" (negative)

Remarks:

The test was negative, i.e. during none of the three trials with the 6 mm orifice as well as with the 2 mm orifice an explosion was observed for the test sample.

Remarks on result:

no ignition, explosion, self-heating or visible decomposition

Interpretation of results:

GHS criteria not met

Conclusions:

The explosive properties of the test sample have been determined according to 440/2008 regulation (A.14 Test) and iso 17025 quality assurance.
Since during none of the tests (thermal, shock and friction sensitivity test) a positive result was obtained, the test sample is not considered to present a danger of explosion in the sense of the regultation 440/2008.

Description of key information

None of the tests (thermal, shock and friction sensitivity test) provide a positive result , the test sample is not considered to present a danger of explosion in the sense of the regultation 440/2008.

Key value for chemical safety assessment

Explosiveness:

non explosive

Justification for classification or non-classification

3 tests have been conducted (thermal, shock and friction sensitivity test) to determine the explosive properties of test substance ((Test A.14 ; regulation 440/2008). As no positive result was obtained, the test sample is not considered to present a danger of explosion in the sense of the regultation 440/2008 (conclusive but not sufficient for classification).
