Administrative data
Link to relevant study record(s)
- Endpoint:
- explosiveness, other
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- February - March 2004
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with national standard methods with acceptable restrictions
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.14 (Explosive properties)
- Principles of method if other than guideline:
- The test substance was tested for mechanical sensitivity (shock and friction). The principles of the test methods including their deviations to the guideline are described in detail in the IUCLID field "any other information on materials and methods"
- GLP compliance:
- not specified
- Key result
- Parameter:
- sensitiveness to impact: impact energy (J)
- Value:
- 40
- Remarks on result:
- not sensitive to impact using an impact energy of 40 J
- Key result
- Parameter:
- sensitiveness to friction: friction load (N)
- Value:
- 360
- Remarks on result:
- not sensitive to friction using a friction load of 360 N
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The two tests for mechanical sensitivity to friction and shock showed no explosive properties of 1,1-Dimethylurea.
- Executive summary:
The study was conducted according to a slightly different method than guideline A.14 and investigated the mechanical sensitivity to friction and shock of 1,1 -Dimethylurea. The thermal sensivity was not investigated. The results show no explosive properties of 1,1 -Dimethylurea as the test substance is not sensitive to shock and friction.
Reference
Mechanical sensitivity (friction): No scorch marks on the clay plate or the wooden lag and changes in the substance were observed in all six tests.
Mechanical sensitivity (shock): No scorch marks on the driving band or the underlayment and no change of the substance at any sample were observed.
Description of key information
The substance 1,1-Dimethylurea does not contain any chemical groups present in the molecule which are associated with explosive properties.
Furthermore a study was conducted according to a slightly different method than guideline A.14 and investigated the mechanical sensitivity to friction and shock of 1,1 -Dimethylurea. The thermal sensivity was not investigated. The results show no explosive properties of 1,1 -Dimethylurea as the test substance is not sensitive to shock and friction.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
Justification for classification or non-classification
The substance 1,1-Dimethylurea does not contain any chemical groups present in the molecule which are associated with explosive properties.
Furthermore a study was conducted according to a slightly different method than guideline A.14 and investigated the mechanical sensitivity to friction and shock of 1,1 -Dimethylurea. The thermal sensivity was not investigated. The results show no explosive properties of 1,1 -Dimethylurea as the test substance is not sensitive to shock and friction.
Therefore 1,1 -Dimethylurea does not have to be classified.
