Description of key information

The substance has not to be classified as flammable solid, flammable gas, flammable liquid, pyrophoric solid, pyrophoric liquid, flammable in contact with water, flammable aerosol or self-heating substance.

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Flammable solids (reference 4.13-1)

In accordance with section 1 of REACH Annex XI, the study does not need to be conducted for a substance with a low melting point. It was concluded that the flash point is the appropriate test to classify the substance for the respective hazard class. Thus, the substance was not considered for classification as flammable solid.

Flammable liquids (reference 4.11-1)

A study was conducted according to Regulation (EC) No 440/2008 method A.9 to determine flash point of the test item using a closed cup method (reference 4.11 -1). The start temperature for the main test (200 °C) was chosen based on the preliminary test. Therefore 4 mL of the test item are filled in the cup and heated to the estimated temperature. Then the substance was maintained for at least 1 minute at this temperature. The flame was dipped in the cup and it was checked if ignition occurred. The measured flash point at atmospheric pressure was corrected to a standard pressure of 1013 hPa. The flash point was determined to be at 198.0 °C (corrected to the ambient pressure). Thus, the flash point of the test item was determined to be 198.0°C (corrected and rounded down to the nearest multiple of 0.5 °C) at 1013.25 hPa.

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 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 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)

In accordance with column 2 of Regulation (EC) No 1907/2006Annex VII and section R.7.1.10.7 of ECHA guidance IR/CSA, the UN Test method N.4 for self-heating substances and mixtures do not need to be conducted as the substance is a solid with a melting point below 160 °C.

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

Section 2.4.2 of Guidance on the application on the CLP Criteria state as follows:

“Aerosols, this means aerosol dispensers, are any non-refillable receptacles made of metal, glass or plastics and containing a gas compressed, liquefied or dissolved under pressure, with or without a liquid, paste or powder, and fitted with a release device allowing the contents to be ejected as solid or liquid particles in suspension in a gas, as a foam, paste or powder or in a liquid state or in a gaseous state." Thus, as the substance does not meet the definition for aerosol, the test for aerosols was waived. Consequently the substance has not to be considered for classification for this hazard class.

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, Section 2.12 of Regulation (EC) No. 1272/2008, as amended for the 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, substances which in contact with water emit flammable gases in Class 4 Division 4.3, pyrophoric liquid, pyrophoric solid in class 4 Division 4.2, flammable gases in class 2 or as aerosol in class 2.
