Preliminary test

The result of the preliminary test with the search program is summarized in the following Table 1. The result “ignition” is indicated by “+” and “no ignition” by “-”. In the preliminary test, no ignition occurred until a temperature of 80.0 °C since evaporating test item extinguished the test flame.

Main test

The results of the main test are summarized in the following Table 2. The result “ignition” is indicated by “+” and “no ignition” by “-”. In both main test measurements, the test flame is extinguished at every dip by evaporating test item. The measurements of the main test were terminated at 105.0 °C.

The atmospheric pressure was documented. The main test was performed twice

Verification measurements

The test results of the verification measurements are presented in the following Table 3. An ignition is indicated by “+” and no ignition by “-”. During the verification measurements it was established that the test item has no flash point up to a temperature of 200.0 °C.

Interpretation of results:
GHS criteria not met
Conclusions:
The test item is neither classified as flammable liquid under UN Transport Regulation, nor under CLP Regulation (EC) No 1272/2008.
Executive summary:

In a GLP study according to EU Method A.9, the test item's flash point was investigated using the closed-cup method. To a temperature of 200 °C, no flash point was determined. Thus it is classified the following:

UN Transport Regulation: Not classified as flammable liquid of UN Class 1,2 or 3.

GHS/CLP Regulation: Not classified as flammable liquid.

Description of key information

In a GLP study according to EU Method A.9, the test item's flash point was investigated using the closed-cup method. To a temperature of 200 °C, no flash point was determined. Thus it is classified the following:


UN Transport Regulation: Not classified as flammable liquid of UN Class 1, 2, or 3.


GHS/CLP Regulation: Not classified as flammable liquid.
