The corrected mean value of both measured flash points to standard pressure is 84.42°C. The resulting average corrected flash point rounded down to the nearest multiple of 0.5°C is 84.0 °C.

Interpretation of results:
Category 4 (combustible liquids) based on GHS criteria
Remarks:
EU-CLP criteria not met
Conclusions:
The substance is NOT classified as flammable liquid according to CLP criteria (>60°C).
GHS Flam.Liq.4 (< 93°C).
Executive summary:

The flash point of the test substance was determined under GLP according to ISO 2719 (listed in EU guideline), using a closed cup equilibrium method. The measured value was corrected to normal atmospheric pressure.

The normal flash point of test substance has been determined to be 84°C.

Description of key information

The substance is NOT classified as flammable liquid according to Regulation (EC) N°1272/2008 (CLP) criteria.
The substance is classified as FLAMMABLE LIQUID category 4 according to UN GHS criteria.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
84 °C

Additional information

A fully reliable experimental study, conducted according to a recognized EC/ISO method (closed cup), is available. It is considered as a key study, and the result is retained as key data.

This study is relevant for the classification regarding flammable properties.
