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

Individual Results:

Preliminary test:

The test item was tested without pre-treatment. The test item could not be ignited with a flame.

The performance of the main test was not necessary.

Interpretation of results:

GHS criteria not met

Conclusions:

The test item was not considered for classification as flammable solid.

Executive summary:

A study was conducted according to Regulation (EC) No 440/2008 Part A A.10 to determine the flammability of the test substance. The test item was tested without pre-treatment. The test item could not be ignited with a flame in the preliminary test. Therefore the performance of the main test was not necessary. The test item was not considered for classification as flammable solid.

Data waiving:

study technically not feasible

Justification for data waiving:

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

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

Endpoint:

self-heating substances / mixtures

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted because the substance is completely molten at 160°C

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 solid, flammable gas, flammable liquid, pyrophoric solid, self-heating substance or flammable in contact with water.

Key value for chemical safety assessment

Flammability:

not classified

Additional information

Flammable solids

A study was conducted according to Regulation (EC) No 440/2008 Part A A.10 to determine the flammability of the test substance. The test item was tested without pre-treatment. The test item could not be ignited with a flame in the preliminary test. Therefore the performance of the main test was not necessary. The test item was not considered for classification as 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 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.

 

Pyrophoric solids

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). Thus, no study was conducted and the substance was not considered for classification as pyrophoric solids.

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.

 

Self-heating substances and mixtures

In accordance with column 2 of REACH Annex VI the classification procedure for this hazard class need not to be applied because the test item is a solid with a melting point below 160 °C.

 

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 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 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, Section 2.12 of Regulation (EC) No 1272/2008, as amended for tenth time in Regulation (EC) No. 2017/776, and UN GHS Rev 6 (2015) 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, 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.
