Flash point:

The flash point was determined to be 125 °C using the Pensky-Martens closed cup method.

Auto flammability:

The self-ignition temperature was determined to be 400 °C.

(Source: GESTIS substance database; Institut für Arbeitsschutz der Deutschen Gesetzlichen Unfallversicherung)

Flammability:

Study is scientifically unjustified. The flammability of liquids is determined on basis of their flashpoint, their ability to emit flammable gases upon contact with water and their pyrophoricity. The molecular structure of LZ52 does not contain groups that indicate potential reactivity with water or pyrophoric properties and handling of the substance indicates that this is the case.

Explosiveness:

Based on chemical structure and information on handling and use the substance was considered non-explosive. Experimental determination was waived.

(Source: internal expert assessment)

Oxidizing properties:

From the assessment of the chemical structure it was established that the test substance would not have oxidizing properties.
