Screening test

For the determination of the initial temperature of flash point measurement a screening test was performed with the test item. The sample was heated from 30 °C using 5.5 °C/min heating rate. Based on this preliminary test the flash point of the test item was determined to be: 37.5 °C.

Main test

In the course of the study three subsequent tests with the test item were carried out. The measured flash points of the test item were: 37.5 °C, 38.5 °C and 38.5 °C, resulting in a mean value: 38 °C.

Interpretation of results:
Category 3 (flammable liquids) based on GHS criteria
Conclusions:
The flash point of the test item was determined to be 38 °C.
Executive summary:

A study was conducted according to Regulation (EC) No 440/2008 method A.9 to determine the flash point of the test item using a closed cup method with Pensky-Martens apparatus. A preliminary test was performed to determine the rough flash point. For the main test about 2 mL of the test item were filled in the cup. The estimated flash point from the preliminary test was used as target temperature for the main test - 37.5 °C. Three subsequent tests with the test item were carried out. The measured flash points of the test item were: 37.5 °C, 38.5 °C and 38.5 °C, resulting in a mean value: 38 °C at 1013.25 hPa.

Description of key information

The flash point of the test item was determined to be 38 °C.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
38 °C
