burning rate test: preliminary screening test

Burning time:

39 s

Key result

Test procedure:

burning rate test over 100 mm length

Burning time:

19 s

Results
Preliminary Test
The pile burned over a distance of 200 mm within 39 seconds. Therefore the main test was necessary.

 

Main Test
The test item was ignited with a flame and burned down over a distance of 100 mm in 19 seconds. The test was not repeated as the burning time was below 45 seconds.

 

Conclusion: The burning time was faster than 45 s, thus the test item is highly flammable according to the European Commission Regulation (EC) No. 440/2008, Method A.10.

Interpretation of results:

Category 2 (flammable solids) based on GHS criteria

Conclusions:

The burning time was faster than 45 s, thus the test item is highly flammable according to the European Commission Regulation (EC) No. 440/2008, Method A.10.

Executive summary:

Due to the fact that the burning time was faster than 45 s, the test item is highly flammable according to the European Commission Regulation (EC) No. 440/2008, Method A.10.

Description of key information

Flammable solids

A test according to Regulation (EC) No 440/2008 method A.10 was performed to determine the flammability of the test substance. The preliminary test and the main test was performed. Due to the fact that the burning time was faster than 45 s in the main test, the test item is highly flammable according to the European Commission Regulation (EC) No. 440/2008, Method 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 is self-reactive and flammable.

 

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 2.12.4.1(b) 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 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.

Key value for chemical safety assessment

Flammability:

flammable

Justification for classification or non-classification

Due to the fact that the burning time was faster than 45 s, the test item is highly flammable according to the European Commission Regulation (EC) No. 440/2008, Method A.10. Thus, the substance is a flammable solid, category 2.
