Findings

Pre-Test for Safety

All observations are presented in the following table.

 

All observations were made on the surface due the dark colour of the test item.

Observations of safety Pre-test

Observations		Temperatures in °C
Formation of Bubbles visible		170
Strong boiling, heating plat switched off		200
No Bubbles visible anymore		175

 

After cooling down the appearance of the test item was visually unchanged.

Determination of the Flash Point

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

Findings

Program		Expected flash point (setting) in °C		Flash point (found) in °C		Mean in °C		Notes
Search		200		25.3				not used for calculation (pre-test)
EN ISO 2719-B		25.0*		27.5**		27.5		difference < 2 K
EN ISO 2719-B		25.0*		27.5

 

The measurements were conducted on 09. Apr. 2020.

 

*The test vessel with the test item was precooled to 7.1 °C for the first determination and to 6.1 °C for the second determination.

**Flame was visible

Evaluation and Result

The flash point is given as the mean value of the duplicate determination. The measured flash point is therefore 27.5 °C (corresponding to 300.7 K).

Therefore, the flash point is given as 27.5 °C (corresponding to 300.7 K).

Discussion

The difference between the two values which were measured was below 2 K (no difference). For this reason, the determination was considered valid.

No observations were made which might cause doubts on the validity of the study outcome. Therefore, the result of the study is considered valid.

Interpretation of results:

Category 3 (flammable liquids) based on GHS criteria

Conclusions:

The flash point is given as 27.5 °C (corresponding to 300.7 K).

Executive summary:

The flash point of the test substance was determined under GLP according to ISO 2719:2003 (listed in EU Method A9), a non-equilibrium closed cup method.

A pre-test and a main study with two experiments were performed. The flashpoint value is the mean value of two independent valid determinations.

Description of key information

The measured flash point is therefore 27.5 °C (corresponding to 298.7 K).

The substance is classified according to Regulation (EC) N°1272/2008 (CLP) criteria and is classified as Flammable Liquid (Category 3).

Key value for chemical safety assessment

Flash point at 101 325 Pa:

27.5 °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 -B). It is considered as a key study.

This study is relevant for the classification regarding flammable properties.
