- Study period:
- 11/03/2010 - 12/03/2010
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Study according to international guideline (EU method A.16) under GLP. No deviations from guideline reported.
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.16 (Relative Self-Ignition Temperature for Solids)
- Deviations:
- no
- Principles of method if other than guideline:
- Not relevant
- GLP compliance:
- yes (incl. QA statement)
- Relative self-ignition temperature:
- 430 °C
- Remarks on result:
- other: the test substance showed a sharp exothermic reaction at this temperature. Therefore no self heating below an oven temperature of 400C appeared.
- Remarks:
- at atm. press. of 99.1 kPa
- Conclusions:
- Steam activated carbon is not auto-flammable according to the criteria in EEC Directive 92/69 A.16.
- Executive summary:
The auto-flammability of this activated carbon was determined according to EU Method A.16 under GLP. The auto-flammability temperature was found to be 430 degrees Celsius at 99.1 kPa. Therefore this activated is not considered to be auto-flammable according to the criteria in EEC Directive 92/69 A.16.
- Endpoint:
- auto-flammability
- Type of information:
- experimental study
- Adequacy of study:
- weight of evidence
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Non-GLP study according to international guideline (UN manual of tests and criteria, Part III, Section 33.3.1.6, Test N4, Test method for self heating substances).
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- according to guideline
- Guideline:
- other: UN manual of tests and criteria, Part III, Section 33.3.1.6, Test N4, Test method for self heating substances
- Deviations:
- no
- Principles of method if other than guideline:
- Not relevant
- GLP compliance:
- no
- Relative self-ignition temperature:
- > 200 °C
- Remarks on result:
- other: Negative result reported (< 200 degrees Celsius), no atmospheric pressure reported
- Conclusions:
- Activated Carbon - High Density Skeleton (AC - HDS) is not a self-heating substance of class division 4.2 substances according to IMDG.
- Executive summary:

Description of key information
Activated Carbon - High Density Skeleton show no self heating properties as defined in the Dangerous Substances Directive, CLP and the UN recommendations on transport, manual of test and criteria, part III.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 430 °C
Additional information
The property auto flammability is not linked to a specific composition of activated carbon as the variation in this property occurs accros any range of compositions of activated carbon. Hence, the classification cannot be linked to a specific composition.
Testing an individual type of activated carbon is the only reliable method to assertain the autoflammability properties of that specific type of carbon.
Activated Carbon - High Density Skeleton show no self heating properties as defined in the Dangerous Substances Directive, CLP and the UN recommendations on transport, manual of test and criteria, part III.
