Deviations:
no
GLP compliance:
yes (incl. QA statement)
Key result
Relative self-ignition temperature:
>= 120 °C
Remarks on result:
preliminary test

The pure test item Tetrahydrofolic acid indicated a self-heating and a self-ignition at atmospheric pressure starting at a temperature of 120 °C.

Due to the low self-heating temperature in the Grewer Oven, self-heating cannot be excluded for higher volumina. Further tests have to be performed for the classification.

Conclusions:
The pure test item Tetrahydrofolic acid indicated a self-heating and a self-ignition at atmospheric pressure starting at a temperature of 120 °C.
Due to the low self-heating temperature in the Grewer Oven, self-heating cannot be excluded for higher volumina. Further tests have to be performed for the classification.

Description of key information

Auto flammability: self-heating starts at > 120°C at 1013 hPa (UN Recommendations on the TRANSPORT OF DANGEROUS GOODS: Manual of Tests and Criteria, Rev. 6 (2015), VDI 2263 Sheet 1 Grewer Oven (1990), preliminary test, GLP)

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
120 °C

Additional information

The pure test item Tetrahydrofolic acid indicated a self-heating and a self-ignition at atmospheric pressure starting at a temperature of 120 °C.

Due to the low self-heating temperature in the Grewer Oven, self-heating cannot be excluded for higher volumina. Further tests have to be performed for the classification.
