Pre-Test for Safety

The following observations were made:

Table 1: Observations Pre-test

Observations	Temperatures
Individual bubbles rising up	61.3 °C
More bubbles	191.9 °C
Test sample getting dark-brown, hardly visible	221.4 °C
Boiling chain, gas burner switched oft	284.1 °C
Boiling chain broke	266.9 °C

After cooling down the test substance was a dark brown liquid.

Determination of the Flash Point

The results of the determinations are presented in the following Table 2.

Table 2: Findings

Program	Expected flash point (setting) / °C	Flash point (found) / °C	Mean / °C	Notes
SEARCH	267	73		not used for calculation (pre-test)
EN ISO 2719-A	73	79.5	80	difference < 2 K
EN ISO 2719-A	73	80.5

Evaluation and Result

The flash point is given as the mean value of the duplicate determination. The measured flash point is therefore 80.0 +- 0.5 °C (corresponding to 353.2 +- 0.5 K).

Interpretation of results:

other: No classification according to CLP criteria

Conclusions:

The flash point of the test item was determined according to EU A.9. and found to be 80 °C at 1013 hPa.

Executive summary:

The flash point of the test item was determined according to EU A.9. and found to be 80 °C at 1013 hPa.

Description of key information
