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:
other:
Justification for type of information:
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 2.10.4.2 the classification procedure for pyrophoric solids need not to 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.
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
Endpoint:

Description of key information

The test item is not a combustible solid or a flammable solid according to UN Test N.1.

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

According to " Recommendations on the TRANSPORT OF DANGEROUS GOODS: Manual of Tests and Criteria, 6th edition, New York and Geneva, 2015: Class 4, Division 4.1: Readily Combustible Solids, Test N.1" and VDI 2263, sheet 1 the test item was assessed for flammability of solids. The test item could not be ignited applying a flame as ignition source for at least 2 minutes. The test item melted.

 

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 2.10.4 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 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.

 

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,substances with a low melting point (< 160 °C) should not be considered for classification in this class since the melting process is endothermic and the substance-air surface is drastically reduced. The study on self-heating properties has not to be conducted as the melting point of the test substance is far below 160 °C (38.5 °C) and the substance iscompletely moltenup to this temperature.

 

Substances which, in contact with water, emit flammable gases

In accordance with column 2 of REACH Annex VII 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 does not have 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
