Specific details on test material used for the study:

SOURCE OF TEST MATERIAL
- Source: Provided by sponsor
- Batch/Lot Number: 150701
- Expiration date of the lot/batch: 14 July 2017

STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: Controlled Room Temperature (15-25˚C), protected from humidity, under inert gas

Flash point:

> 200 °C

Remarks on result:

other: atmospheric pressure not specified

Two replicates were carried out after the preliminary test and no flash point of the test material was observed until 200 °C.

Interpretation of results:

other: No flash point observed

Conclusions:

Under the conditions of the study, no flash point of the test material has been observed until 200 °C.

Executive summary:

The relative flash point of the test material was investigated in accordance with the standardised guideline EU Method A.9 under GLP conditions.

After filling approximately ¾ of the chamber with the sample the stirring magnet was inserted into the cup and it was placed into the tester. The electrodes were cleaned and the sample cup was pressed onto the oven plate. The sample temperature and initial temperature were checked. When the sample has reached the preset starting temperature, the automatic flash point determination was started. The first ignition for a flash test was initiated and the pressure increase was monitored. The oven temperature was raised with the programmed rate and arcs were initiated at every preset step. To have enough oxygen for each arc to develop a flame, a small amount of air was blown into the measuring chamber before each ignition. The measuring procedure was continued until the pressure increase after an arc exceeded the programmed threshold.

Under the conditions of the study, no flash point of the test material has been observed until 200 °C.

Description of key information
