Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Explosiveness
Administrative data
Link to relevant study record(s)
- Endpoint:
- explosive properties of explosives
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 16/07/2002
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Remarks:
- No guideline is cited, but test conditions are sufficiently described. The substance identification is not complete (composition missing). Therefore validation applies with restrictions.
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- DSC screening test, in accordance with UN TDG, MTC Appendix 6.
- GLP compliance:
- no
- Key result
- Parameter:
- other: DSC screening test (J/g)
- Value:
- 308
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Based on UN MTC Appendix 6 criteria, the exothermic decomposition energy is less than 500 J/g. Therefore the acceptance procedure for Class 1 explosives need not be applied.
No additional testing is required. The substance It shall not be classified as explosive according to Regulation (EC) N°1272/2008 (CLP). - Executive summary:
The thermal stability of the test substance was tested with Differential Scanning Calorimetry, in accordance with conditions recommended in UN MTC screening procedure. An exothermal reaction was observed from ca 380°C, and still at the maximum test temperature of 500°C. In this range, the energy released was 308 J/g.
Reference
A small exotherm was recorded at ca 170°C.
A small endotherm, starting at ca 280°C, precede a wide exotherm from ca 380°C up to the maximum test temperature. The response is not a peak, after a rise up to ca 430°C the trace is then quite constant up to 500°C.
The energy released was 308 J/g (signal area).
Description of key information
DSC screening test: Exothermal reaction starting from ca 380°C, but with limited decomposition energy of 308 J/g up to 500°C.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
A reliable experimental study, conducted in accordance with conditions recommended in UN MTC screening procedures, is available. Despite restrictions due to substance characterisation, it is considered as a key study. The result is retained as key data.
No further testing is required.
Justification for classification or non-classification
The substance is NOT classified as explosive according to CLP criteria, based on screening procedures (exothermic decomposition energy < 500 J/g).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
