Flammability (solids)

Preliminary test:

The test item was tested without pre-treatment. The test item could not be shaped with a mould due to its stickiness. Therefore, a triangular pile of the test item in the shape usually obtained with the mould was formed with a spatula.

After the ignition with a flame the test item burned shortly and then the flame extinguished.

The performance of the main test was not necessary.

Interpretation of results:

non flammable

Remarks:

Migrated information

Conclusions:

The test item did not ignite during the preliminary test and thus was considered to be a non-flammable solid.

Executive summary:

A preliminary test with the source substance according to UN N.1 and Regulation (EC) No 440/2008 method A.10 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 was performed twice. In the preliminary test the test item could not be ignited. Based on the results of the preliminary test, no main test was performed. The test item is considered as a not readily combustible solid of Division 4.1. and is not a flammable solid.

Endpoint:

substances / mixtures which in contact with water emit flammable gases

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water

Description of key information

The substance doesn't have not to be considered as flammable gas, flammable liquid, flammable solid, flammable in contact with water, flammable aerosol, pyrophoric solid, pyrophoric liquid or self-heating substance.

Key value for chemical safety assessment

Flammability:

not classified

Additional information

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 solids

A preliminary test with the source substance according to UN N.1 and Regulation (EC) No 440/2008 method A.10 was performed to determine the flammability of a read-across substance. The source substance 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 was performed twice. In the preliminary test the source substance could not be ignited. Based on the results of the preliminary test, no main test was performed. The source substance is considered as a not readily combustible solid of Division 4.1. and is not a flammable solid.

 

It was concluded that the flammable properties for the source and the target substance are comparable. The source substance represents the worst case as the respective aliphatic c-chain is shorter and thus the oxygen carbon ration is higher in the source substance than in the target substance. As the source substance does not ignite in the preliminary test it was concluded that the target substance can be regarded as non-combustible solid.

 

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 2.9.4.2 the classification procedure for pyrophoric solids need not to be applied when experience in manufacture or handling shows that the solid does not ignite spontaneously on coming into contact with air at normal temperatures (i.e. the liquid is known to be stable at room temperature for prolonged periods of time (days)). 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.

 

Substances which, in contact with water, emit flammable gases

In accordance with column 2 of REACH Annex VI and with Regulation (EC) No 1272/2008 Annex I section 2.12.4 and ECHA guidance on the application of CLP Criteria section 2.12.4.2 the classification procedure for this hazard class need not to 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.

 

Self-heating substances and mixtures

In accordance with ECHA guidance on the Application of the CLP Criteria section 2.11.4.2 and ECHA guidance on IR/CSA chapter R.7a section R7.1.10.7 the test does not to be conducted when the melting point of the test item is less than 160 °C.

 

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.

 

In conclusion, the substance doesn't have not to be considered as flammable gas, flammable liquid, flammable solid, flammable in contact with water, flammable aerosol, pyrophoric solid, pyrophoric liquid or self-heating substance.

Justification for classification or non-classification

Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
