Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Administrative data
Link to relevant study record(s)
- Endpoint:
- explosiveness
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Study period:
- Study was conducted between 8 June and 10 June 2010
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Non-GLP, no guideline experimental investigation (an ad-hoc test accepted by the regulatory authorities).
- Qualifier:
- no guideline available
- Principles of method if other than guideline:
- Exothermic activity determination with Differential Scanning Calorimeter by heating at a constant rate (of up to 20 K.min-1) up to 500°C .
- GLP compliance:
- no
- Interpretation of results:
- other: No explosive properties
- Conclusions:
- Ash does not have exothermic activity up to 500°C. Thus, the test material can be concluded not to have explosive properties.
- Executive summary:
Thermal stability analysis of Ash was performed to support the interpretation of structural analysis, according to which there are no chemical groups associated with explosive properties. The thermal stability analysis was conducted using Differential Scanning Calorimetry (DSC). No exothermic activity was observed up to 500°C (i.e. there were no events with a magnitude of > 500 J.g-1).

Test Results
The full profile for the experiment is provided in Graph 1.
The sample was not observed to undergo any significant energetic events up to 500°C.
Description of key information
Based on molecular structure and thermal stability analysis, Ash does not have explosive properties.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
Thermal stability analysis of Ash was performed to support the interpretation of structural analysis, according to which there are no chemical groups associated with explosive properties. The thermal stability analysis was conducted using Differential Scanning Calorimetry (DSC). No exothermic activity was observed up to 500°C (i.e. there were no events with a magnitude of > 500 J.g-1). Based on this combination of factors, it is beyond reasonable doubt that the material will not exhibit explosive properties. The conduct of the EU Method A.14 tests is therefore not considered appropriate.
Justification for classification or non-classification
Ash is an inorganic substance which does not have explosive properties indicating functional groups (OECD testing methods publication). This result along with thermal stability observed in a Differential Scanning Calorimetry analysis prove that no classification is required.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
