Endpoint:
flammable gases
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is a 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
Endpoint:
pyrophoric liquids
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is a solid
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:
self-heating substances / mixtures
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 completely molten at 160°C

Description of key information

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

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Flammable solids (reference 4.13-1)

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 (reference 4.13-2)

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 (reference 4.11-1)

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 (reference 4.13-3)

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.

Pyrophoric liquids (reference 4.13-4)

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.

Substances which, in contact with water, emit flammable gases (reference 4.13-5)

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.

Self-heating substances/mixture (reference 4.13-6)

In accordance with column 2 of Regulation (EC) No 1907/2006Annex VII and section R.7.1.10.7 of ECHA guidance IR/CSA, the UN Test method N.4 for self-heating substances and mixtures do not need to be conducted as the substance is a solid with a melting point below 160 °C.

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

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

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 twelfth time in Regulation (EU) 2019/521, 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.
