Key result

Flash point:

27.9 °C

Atm. press.:

101.4 kPa

Preliminary test

The preliminary value of the flash point of the test item was found on 30.0 °C at 1.013 bar.

Main test

The flash point is defined as the lowest measured value out of all performed tests.

Sample No.	Start temperature [°C]	Gradient [°C/min]	Measured flash point [°C]	Atmospheric pressure [kPa]	Corrected flash point [°C]
1 2	15 15	1.3 1.3	27.9 27.9	101.4 101.4	27.9 27.9

Interpretation of results:

Category 3 (flammable liquids) based on GHS criteria

Conclusions:

The flash point of the formulation product was determined to be 27.9 °C at 101.4 kPa.

Executive summary:

The flash point of the formulation product was determined according to EEC-guideline 92/69/EWG A.9 and DIN EN 22719/ ISO 2719, using the closed cup method. The formulation product was heated up in a closed crucible and at defined temperatures it was tried to ignite the gaseous phase upon the surface of the liquid with the hot surface. The flash point was determined to be 27.9 °C at atmospheric pressure 101.4 kPa. Therefore the formulation product has to be classified according to Regulation (EC) No 1272/2008, as amended for the tenth time in Regulation (EC) No 2017/776, in Category 2 Flammable liquids.

Description of key information

The test item is a solid, therefore no study on Flash point is needed. As the test item is mainly produced as a formulation product with solvents in liquid form, a study with the formulation product was conducted. The flash point of the formulation product was determined to be 27.9 °C at 101.4 kPa.

Additional information

In accordance with section 1 of REACH Annex XI, the flash point study does not need to be conducted as the substance is a solid.

Additionally, the flash point of the formulation product was determined according to EEC-guideline 92/69/EWG A.9 and DIN EN 22719/ ISO 2719, using the closed cup method. The formulation product was heated up in a closed crucible and at defined temperatures it was tried to ignite the gaseous phase upon the surface of the liquid with the hot surface. The flash point was determined to be 27.9 °C at atmospheric pressure 101.4 kPa. Therefore the formulation product has to be classified according to Regulation (EC) No 1272/2008, as amended for the tenth time in Regulation (EC) No 2017/776, in Category 2 Flammable liquids.
