Executive summary:

A study according to EU method A.12 was conducted. Therefore the test substance was mixed with distilled water at room temperature and the rate of evolution of gas was measured over a period of 7 hours. No gas evolution was observed. Therefore the substance does not evolve gases in contact with water.

Endpoint:

pyrophoric solids

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied

Flammability:

not classified

Additional information

Flammable solids

The test substance did not ignite or propagate combustion during the test according to EU method A.10. The test substance is not flammable in the sense of the directive A.10.

Flammable gases

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.

Flammable liquids

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 flammable liquid.

Pyrophoric liquids 

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

In accordance with section 2.9.4 Annex I of Regulation (EC) No 1272/2008 and ECHA guidance on the application of CLP Criteria section 2.10.4.2 the classification procedure for pyrophoric solids need not be applied when experience in manufacturing or handling shows that the substance or mixture does not ignite spontaneously when coming into contact with air at normal temperatures. Based on the experience in handling and use the substance is not known to ignite spontaneously when coming into contact with air at normal temperatures. Thus, no study was conducted and the substance was not considered for classification as pyrophoric solid.

Self-heating substances/mixture

The substance showed melting and decomposition up to a temperature of 300 °C in a study according to EU method A.1 and did not ignite when being in contact with an ignition source with a temperature of 1000 °C (A.10). Self-heating can be excluded. 

Substances which, in contact with water, emit flammable gases 

A study according to EU method A.12 was conducted. Therefore the test substance was mixed with distilled water at room temperature and the rate of evolution of gas was measured over a period of 7 hours. No gas evolution was observed. Therefore the substance does not evolve gases in contact with water. 

 

Flammable Aerosols

Section 2.4.2 of Guidance on the application on the CLP Criteria states 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 because it is a solid substance, 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

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 the seventeenth time in Regulation (EU) 2021/849, 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.
