Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 943-834-9 | CAS number: -
Flash point
Administrative data
Link to relevant study record(s)
- Endpoint:
- flash point, other
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 9 April 2021 – 14 April 2021
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- ASTM D93 (Standard test methods for flash point by pensky-martens closed cup tester)
- Deviations:
- yes
- Remarks:
- Since the substance was in powder form, it was decided that the recommended heating rate was too fast and the test was carried out at reduced heating rate to enable better heat distribution. No stirring was attempted as the substance was in powder form.
- Type of method:
- closed cup
- Flash point apparatus:
- Pensky-Martens apparatus
- Key result
- Remarks on result:
- other: The results indicate that the material has a non-well defined flash point (probably due to it being a mixture of compounds) at a temperature of 128±6oC.
- Conclusions:
- The flash point of the substance is 128 ± 6oC
- Executive summary:
Dried waste sludge from a biological civic effluent treatment utility was examined to ascertain its flash point.
Flash-point testing was carried out according to ISO 2719 (ASTM D93) “Determination of Flash Point by Pensky-Martens Closed Cup Method”.
The results indicate that the material has a non-well defined flash point (probably due to it being a mixture of compounds) at a temperature of 128±6oC.
Reference
The results indicate that the material has a non-well defined flash point (probably due to it being a mixture of compounds) at a temperature of 128±6oC.
Note: During three of the tests weak flashes were observed at a temperature between 80 oC and 100 oC which indicate that some flammable gases were emitted momentarily from the substance. However, no actual flame (i.e. not a “Flash-point”) was observed as the material also emitted smoke without flame at the same time, potentially suppressing the possible development of a flash-flame.
Description of key information
The substance was tested according ASTM D93 (Standard test methods for flash point by pensky-martens closed cup tester).
Key value for chemical safety assessment

Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
