- Endpoint:
- relative self-ignition temperature (solids)
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is a solid having a melting point <= 160°C
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
In accordance with column 2 of REACh Annex VII, the study does not need to be conducted for solids, if the substance has a melting point ≤ 160 °C, or if preliminary results exclude self-heating of the substance up to 400 °C.
Based on the melting point of ca 80°C (refer to IUCLID section 4.2), and the absence of exothermal reaction up to 400°C observed with DSC (refer to 4.14), testing for self-ignition can be waived. Moreover, considering the ignition failure in the flammability test, in the presence of a flame (under 4.13), self-ignition seems unlikely for the substance. Therefore no additional information is required. - Reason / purpose for cross-reference:
- data waiving: supporting information
- Reason / purpose for cross-reference:
- data waiving: supporting information
- Reason / purpose for cross-reference:
- data waiving: supporting information
- Endpoint:
- auto-ignition temperature (liquids)
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Study period:
- 2003-04-10
- Reliability:
- 4 (not assignable)
- Rationale for reliability incl. deficiencies:
- documentation insufficient for assessment
- Remarks:
- The method can be related to the current guideline for liquids, however the test substance is a solid. Moreover, insufficient experimental details are provided, and purity of the test substance is not stated. Therefore validation cannot be granted.
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
- Deviations:
- yes
- Remarks:
- the test substance is a solid
- GLP compliance:
- no
- Auto-ignition temperature:
- 255 °C
- Atm. press.:
- 965 mBar
- Executive summary:
The auto-ignition temperature of the test substance was measured with an apparatus complying with EU A15 guideline.
However, this method is not designed for solids. Ignition was nevertheless observed, after melting, at ca 255°C.

Description of key information
No further testing is required.
Key value for chemical safety assessment
Additional information
Based on low melting point, testing for relative self-ignition of solids can be waived. Moreover, the substance shows low reactivity to heating and flame.
However, the phenomenon could be experimentally observed at 255°C on the melted substance, so it should be considered that the reaction cannot be totally excluded under specific conditions.
