Key result

Flash point:

ca. 72 °C

Atm. press.:

ca. 101 325 Pa

Pre-Test for Safety

When heating a sample of the test item in an open test tube (10*100 mm) in an aluminium block with a gas burner, formation of bubbles was observed at approx. 230 °C. The bubble chain broke at 213 °C. No signs of change were visible after cooling down.

The test is considered as safe.

Determination of the Flash Point

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

Table 4.11/2    Findings

Program	Expected flash point (setting) in °C	Flash point (found) in °C	Mean in °C	Notes
Search	210	70.6		not used for calculation(pre-test)
EN ISO 2719-B	71.0	72.5	72.0	difference < 2 °C
EN ISO 2719-B	71.0	71.5

Evaluation and Result

The flash point is given as the mean value of the duplicate determination. The measured flash point is therefore 72.0 ± 1.0°C (corresponding to 345.2 ± 1.0 K) at 101325 Pa.

Discussion

The difference between the two values was below 2 °C. For this reason, the determination was considered valid.

 

Interpretation of results:

Category 4 (combustible liquids) based on GHS criteria

Conclusions:

The flashpoint of the test item is stated as 72.0 °C (corresponding to 345.2 K) at 101325 Pa.

Executive summary:

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 as described in ISO2719 -Part B.

The flash point of the test item is stated as 72.0 °C (corresponding to 345.2 K) at 101325 Pa (mean value of two independant determinations).

Description of key information

The substance is not classified according to Regulation (EC) N°1272/2008 (CLP criteria) and it is classified as combustible liquid Category 4 according to 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:

72 °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.
