Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Type of information:
experimental study
Adequacy of study:
key study
Study period:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
test procedure in accordance with national standard methods with acceptable restrictions
equivalent or similar to guideline

Version / remarks:
Principles of method if other than guideline:
The test measures the temperature at which a substance, when heated in an air stream, undergoes an exothermic (or endothermic) reaction. The test is carried out in a Grewer Oven and is monitored using a Sipcon measurement and control system. The oven is heated at a rate of 1°C / minute from room temperature to 500°C. A sample of graphite is used to indicate the oven temperature.
