Accuracy of the method is indicated in the standard:

• repeatability of the method (same operator) : 2 °C (6 °C if flash point > 104 °C),

• reproducibility of the method (different operators) : 3.5 °C (8.5 °C if flash point > 104 °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 A9 guideline), non-equilibrium closed cup method (Pensky Martens apparatus°. The test was carried out in duplicate, and the mean measured value was corrected to normal atmospheric pressure. .

The normal flash point of test substance has been determined to be 84 ±2°C.

Description of key information

The substance is NOT classified as flammable liquid according to CLP Regulation 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 EU method (closed cup) and under GLP, 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.
