Endpoint:
pyrophoric solids
Data waiving:
study technically not feasible
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
Remarks on result:
substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period

Preliminary test

The test item could not be ignited with a flame. The test item melted. The performance of the main test was not necessary.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
The test item is not a highly flammable solid in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.10.
Executive summary:

The test item is not a highly flammable solid in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.10.

Description of key information

The substance is not considered as flammable gas, flammable solid, flammable in contact with water, pyrophoric, and self-heating substance.

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Flammable solids

A preliminary test according to 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.

 

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

No self-ignition temperature was observed up to the maximum test temperature of 401°C, according to the testing guideline for auto-flammability (solids - determination of relative self-ignition temperature) in the sense of the European Commission Regulation (EC) No.440/2008, Method A.16.

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.

 

In conclusion the test substance has 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

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, 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.
