Interpretation of results:
Category 3 (flammable liquids) based on GHS criteria
Conclusions:
The flash point of the test substance is between the classification thresholds of 23 and 60°C (resp. CLP and GHS criteria). Therefore, the substance is classified as a Flammable Liquid cat.3 (H226).
Executive summary:

The flash point of the test substance was measured under GLP according to ISO 2719 (listed in EU guideline A.9), using Pensky-Martens closed cup non-equilibrium method.

Duplicate determinations were performed.

The flash point of test substance has been determined to be 47 ± 2 °C, corrected to normal atmP.

Description of key information

The substance is classified as a Flammable Liquid cat.3 (H226) according to CLP and GHS criteria.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
47 °C

Additional information

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

Note that this parameter may show some variations, due to the UVCB nature of the substance.

This study is relevant for the classification regarding flammable properties. (see IU Section 4.13 for justification of classification)
