- Interpretation of results:
- not classified based on GHS criteria
- Conclusions:
- The test item is not classified as flammable solid.
- Executive summary:
A preliminary test according to UN N.1 was performed to determine the flammability of the test substance. The test item was formed into a powder train. The flame from a gas burner was applied to one end of the powder train for 2 minutes. The burning of the pile was observed.The test item could be ignited at room temperature using a flame as ignition source being applied for at least 2 minutes. The test item burned over 200 mm within more than 120 s (120 s for 35 mm). The test item melted and the melt did also burn. The test item burned very slowly, therefore, the test item is not classified as readily combustible solid in class 4.1 or as flammable solid according to GHS / CLP Regulation EC 1272/2008 Annex 1: 2.7.

Self-ignition in the Grewer Oven
In the investigation of self-ignition in the Grewer Oven for the pure test item a slight endothermic process was detected starting at approx. 50 °C. After the test, the test item in the wire basket was a black mass. No self-ignition could be observed up to the maximum oven temperature of 400 °C.

Preliminary Test
The test item did not ignite at room temperature using a flame as ignition source being applied for at least 2 minutes.
Main Test
In the preliminary test the test item could not be ignited by a flame. Thus, the performance of the main test was not necessary.
Description of key information
The substance has not to be classified as flammable gas, flammable liquid, flammable solid, pyrophoric solid, pyrophoric liquid, flammable in contact with water, flammable aerosol or self-heating substance.

- not classified
Additional information
Flammable solids (reference 4.13-1)
A preliminary test according to UN N.1 was performed to determine the flammability of the test substance. The test item was formed into a powder train. The flame from a gas burner was applied to one end of the powder train for 2 minutes. The burning of the pile was observed. The test item could be ignited at room temperature using a flame as ignition source being applied for at least 2 minutes. The test item burned over 200 mm within more than 120 s (120 s for 35 mm). The test item melted and the melt did also burn. The test item burned very slowly, therefore, the test item is not classified as readily combustible solid in class 4.1 or as flammable solid according to GHS / CLP Regulation EC 1272/2008 Annex 1: 2.7.
Flammable liquids (reference 4.11-1)
In accordance with column 2 Annex VII section 7.9 of Regulation (EC) No 1907/2006 (REACH), the test on flash point does not need to be conducted as the test substance is solid.
Flammable gases (4.13-2)
The test item is a solid at ambient conditions. This hazard class is only applicable for gases. Thus, the substance was not considered for classification as flammable gas.
Pyrophoric properties of liquids (reference 4.13-3)
The test item is a solid at ambient conditions. This hazard class is only applicable for liquids. Thus, the substance was not considered for classification as pyrophoric liquid.
Pyrophoric properties of solids (reference 4.13-4)
In accordance with section 2.10.4.1, Annex I of Regulation (EC) No 1272/2008, the classification procedure for pyrophoric solids need not to be applied when experience in manufacture or handling shows that the substance or mixture does not ignite spontaneously on coming into contact with air at normal temperatures (i.e. the substance is known to be stable at room temperature for prolonged periods of time (days)). Thus, no study was conducted and the substance was not considered for classification as pyrophoric solid.
Self-heating substances and mixtures (reference 4.13-5)
A study was conducted according to VDI 2263, part 1 1990, test methods for the determination of the safety characteristics of dusts; UN Transport Regulations, Appendix 6, Screening Procedures (Substances which may be liable to spontaneous combustion (Division 4.2)) to determine the self-heating properties of the test item. For this purpose, the test item was filled in a small wire basket of a volume of 8 cm³ and this wire-basket was placed into the oven. In this oven, the self-ignition behavior of five samples can be determined simultaneously. An additional basket was filled with a reference material (graphite). The pure test item indicated no self-ignition at atmospheric pressure.It showed a slight endothermic effect starting at a temperature of approx.50 °C. The test item does not have to be classified as self-heating substance in class 4, division 4.2 according to the UN Transport Regulation.
Substances which, in contact with water, emit flammable gases (4.13-6)
In accordance with column 2 of REACH Annex VII and with Regulation (EC) No 1272/2008 Annex I, section 2.12.4.1(b) the classification procedure for this hazard class need not be applied. Based on the experience in handling and use the substance does not react with water and in addition the test substance is not pyrophoric. Thus, no study was conducted and the substance was not considered for classification.
Flammable Aerosols
In accordance with Annex I of Regulation (EC) No. 1272/2008, section 2.3 the classification procedure for this hazard class does not apply, since the test substance is not used as an aerosol. Thus, no study was conducted and the substance was not considered for classification.
Justification for classification or non-classification
Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
In accordance with Annex I section 2.2, section 2.3, section 2.6, section 2.7, section 2.9, section 2.10, section 2.11 and section 2.12 of Regulation (EC) No. 1272/2008, as amended for twelfth time in Regulation (EU) No 2019/521, and UN GHS Rev 7 (2017) the test item has not to be classified as flammable liquid, readily combustible solid in class 4, Division 4.1, self-heating substance in Class 4, Division 4.2, substance which in contact with water emits flammable gases in Class 4, Division 4.3, pyrophoric liquid, pyrophoric solid in class 4, Division 4.2, flammable gas in class 2 or as aerosol in class 2.
