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

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

Key result

Test procedure:

burning rate test: preliminary screening test

Burning time:

254 s

The procedure started with the Preliminary screening test.

A mould with triangular cross section was used to form the test item into a product train on the base plate. The train was ignited at one end using the flame of a gas burner. On exposure to the flame the train started to burn almost instantaneously with an orange to blue flame. The yellowish product gave a black residue after been burned. Propagation of the flame over 200 mm of the train took 254 seconds, which is above the limit value of 4 minutes for a complete burning rate test.

Because of this result in the Preliminary screening test no further testing is required and the test item has to be considered as "not highly flammable".

Interpretation of results:

GHS criteria not met

Conclusions:

The test substance is not classified as flammable solid.

Executive summary:

The flammability of the substance was determined according to EC Method A. 10, Flammability (Solids). In the preliminary screening test the test item did not keep up propagation of combustion at a rate faster than the limit value for continuation of the experimental testing procedure (254 s). A full burning rate test was therefore not required and it has to be concluded that the test item is not highly flammable.

Description of key information

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

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 liquid

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.

 

Flammable solids

The flammability of the substance was determined according to EC Method A. 10, Flammability (Solids). In the preliminary screening test the test item did not keep up propagation of combustion at a rate faster than the limit value for continuation of the experimental testing procedure (254 s). A full burning rate test was therefore not required and it has to be concluded that the test item is not highly flammable.

 

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 flammable liquid.

 

Pyrophoric solids

In accordance with section 2.10.4 Annex I of Regulation (EC) No 1272/2008 and ECHA guidance on the application of CLP Criteria section 2.10.4.1 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 solid 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.

 

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 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

In accordance with Annex I Section 2.2, Section 2.3, 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 fifteenth time in Regulation (EU) 2020/1182, and UN GHS Rev 8 (2019) the test item has not to be classified as, readily combustible solid in class 4 Division 4.1, flammable liquid, 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.
