Justification for data waiving:

the study does not need to be conducted because the substance is a solid

Justification for type of information:

According to the laboratory, the Test N.1: Test method for readily combustible solids, could not be performed with the test substance based on the nature of the test item which is a paste. Alternatively, the flash point study was conducted with the test item (see IUCLID section 4.11).

Reference 3

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

Reference 4

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

Reference 6

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

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, pyrophoric liquid or self-heating substance.

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

This endpoint is obsolete as covered by IUCLID section 4.11 Flash point

Flammable solids

According to the laboratory, the Test N.1: Test method for readily combustible solids, could not be performed with the test substance based on the nature of the test item which is a paste. Alternatively, the flash point study was conducted with the test item (se IUCLID section 4.11).

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.

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.

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 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 and mixtures

According to section 2 of REACH Annex XI, the test on self-heating substances does not need to be conducted because there are no chemical groups present in the molecule associated with self heating properties. Therefore, no test on self-heating is required.

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.

 

Conclusion

In conclusion the substance has not to be considered as flammable gas, flammable liquid, flammable solids, 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 2.9, Section 2.10 Section 2.11, Section 2.12 of Regulation (EC) No 1272/2008, as amended for the twelfth time in Regulation (EU) No 2019/521, and UN GHS Rev 7 (2017) the test item has not to be classified as, flammable liquid, flammable solid, self-heating substance in Class 4 Division 4.2, 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.
