Key result

Test procedure:

other: determination of combustion factor at room temperature with dried substance

Remarks on result:

other: Burning index 3

Test procedure:

other: determination of combustion factor at ambient temperature of 100 °C

Remarks on result:

other: Burning index 3

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The test item is not a flammable solid.

Executive summary:

The flammability of the test item was determined according to the German guideline VDI 2263, sheet 1, which is similar to European Commission Regulation (EC) No. 440/2008, Method A.10.

The test substance was subject to a stepwise testing procedure:

1) Tested as delivered at room temperature.

2) Test of dried substance at room temperature.

3) Tested at heightened product temperature (100 °C) in a drying cabinet with sufficient air supply.

In all three tests the test substance was applied to a ceramic plate as a ca. 2 cm wide and 4 cm long bulk. For the ignition a micro burner with temperatures above 1000 °C was used. The reaction behaviour of the test substance was judged visually after removal of the burner.

For all three tests a burning index of 3 was determined.

The test item is not a highly flammable solid in the sense of the German guideline VDI 2263, sheet 1, as well as in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.10.

The test item is not a flammable solid according to section 2.7.4.2 in the ECHA Guidance on the Application of the CLP Criteria (Guidance to Regulation (EC) No 1272/2008 on classification, labelling and packaging (CLP) of substances and mixtures, Version 4.1, June 2015).

Description of key information
