Determination of the Flash Point

The results of the determinations are presented in the following tables.

Evaluation and Result

The flash point is given as the mean value of the duplicate determination. The measured flash point is therefore 43.5°C (corresponding to 316.7 K).

Discussion

Both determinations showed no difference. Therefore, the validity criterion is met and the determination was considered valid.

Interpretation of results:

Category 3 (flammable liquids) based on GHS criteria

Conclusions:

The flash point of test substance is below the classification thresholds of 60°C (CLP criteria) or 93°C (GHS criteria). Therefore the test substance is classified as a flammable liquid.

Executive summary:

The flash point of the test substance was determined under GLP according toEU Method A.9 (Flash-Point), using a non-equilibrium closed cup method (ISO2719 -Part B).

A pre-test and a main test with two experiments were performed using a flashpoint tester.

The flashpoint ofthe test item is stated as 43.5 °C (corresponding to 316.7 K).

This value is the mean value of two independent determinations.

The flash point of test substance is lower than the classification thresholds of 60°C of the Regulation (EC) No. 1272/2008 (CLP criteria) and UN Globally Harmonised System (GHS).

Therefore the test substance is classified as a flammable liquid Category 3 according to CLP criteria and according to UN Globally Harmonised System (GHS).

Description of key information

The flash point of the test item was stated as 43.5°C.

The substance is classified as a FLAMMABLE LIQUID Category 3 according to Regulation (EC) N°1272/2008 (CLP criteria) and UN Globally Harmonized System (GHS criteria).

Note that the result obtained on this kind of substance should be largely influence by small amounts of volatile constituents.

Key value for chemical safety assessment

Flash point at 101 325 Pa:

43.5 °C

Additional information

The flash point of the test substance was determined under GLP according to EU Method A.9 (Flash-Point), using a non-equilibrium closed cup method (ISO2719 -Part B). It is considered as a key study. The result is retained as key data for purpose of CSA.

This study is relevant for the classification regarding flammable properties.
