Description of key information

The flash point of di-tert amyl peroxide, corrected at the pressure of 101.3 kPa, is 29°C ± 0.5°C.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
29 °C

Additional information

A guideline test with a well detailed study report is available.

The flash point of di-tert amyl peroxide is 29°C at atmospheric pressure (101.3 kPa).

Based on this result, and taking into account the value of SADT of this organic peroxide (Self-Accelerating Decomposition Temperature, >75°C), di-tert-amyl peroxide is classified Flammable Liquid Cat3 under EU regulation 1272/2008 CLP.
