Interpretation of results:
GHS criteria not met
Conclusions:
The flash point is given as the mean value of the duplicate determination. The measured flash point is therefore 244.5 ± 1.0 °C (corresponding to 517.7 ± 1.0 K).
Executive summary:

Title of Study: Determination of the flash point of Hatcol 1570 according to EU Method A.9, OPPTS 830.6315 and UN Manual Test Methods 32.4

 

Findings and Results:

First, a safety test was performed: approx. 3 mL of the test item was heated with a Bunsen burner up to 400 °C. The appearance had not changed after cooling down.

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

The flashpoint of Hatcol 1570 is stated as 244.5 ± 1.0 °C (corresponding to 517.7 ± 1.0 K).

This value is the mean value of two independent determinations.
