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

Safety Pre-Test

The test item liquefied, boiled and burned with a yellow flame.

 

Preliminary Screening Test

The test item liquefied, boiled and burned shortly with a yellow flame. The flame died immediately after removing the burner.

No observations were made which might cause doubts concerning the validity of the study outcome.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The test item is NOT classified as a flammable solid according to Regulation (EC) N°1272/2008 (CLP) and UN GHS criteria.

Executive summary:

The substance was tested for its flammable properties, according to EU-Method A.10 and UN MTC N1 guideline, and under GLP.

During the preliminary assay, the test item was heated with the flame of a teclu burner. The test item liquefied, boiled and burned with a yellow flame. However, the flame died immediately after removing the burner. Therefore no propagation of a flamme within the 2-min duration of application of the burner flame was observed and no main test was performed. Finally the substance is considered as NOT classified as a flammable solid according to Regulation (EC) N°1272/2008 (CLP) and UN GHS criteria.

Endpoint:

pyrophoric liquids

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

the study does not need to be conducted because the organic substance does not contain metals or metalloids and hence, the classification procedure does not need to be applied

Justification for type of information:

JUSTIFICATION FOR DATA WAIVING
In accordance with section 1 of REACh Annex XI, study for pyrophoric properties is deemed unnecessary based on the experience in handling, testing and use of the substance and based on the chemical structure of the known constituents of the substance that do not fall into critical categories described in ECHA guidance.
A review of the chemical structure of the known constituents suggests that there are no chemical groups present in these constituents that would imply pyrophoric properties. Moreover, the tests performed on the substance and reported in this dossier showed that the substance clearly does not react with air. Therefore, the study was considered as unnecessary.

Reference 3

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 organic substance does not contain metals or metalloids and hence, the classification procedure does not need to be applied

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

Justification for type of information:

JUSTIFICATION FOR DATA WAIVING
In accordance with section 1 of REACh Annex XI, study for flammability if contact with water is deemed unnecessary based on the experience in handling and use of the substance and based on the chemical structure of known constituents of the substance that do not fall into critical categories described in ECHA guidance.
A review of the chemical structure of the known constituents suggests that there are no chemical groups present that would imply flammability on contact with water. In addition, the information from aquatic test conducted on the substance (Daphnia/algae aquatic toxicity tests performed) showed that the substance clearly does not react with water.
Finally,no experience in handling and use of the registered substance has been reported, which could cast doubt on the NON-flammability if contact with water of the extract.
Therefore, the study was considered as unnecessary.

Reference 4

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 a liquid

Justification for type of information:

JUSTIFICATION FOR DATA WAIVING:
According to the Guidance on the Application of the CLP Criteria, v5.0 of July 2017, $ 2.11.4.2:
"the phenomenon of self-heating applies only to solids. The surface of liquids is not large enough for reaction with air and the test method is not applicable to liquids. Therefore liquids are not classified as self-heating…"
In addition,
"Substances or mixtures 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. However, this criterion is only applicable if the substance or mixture is completely molten up to this temperature.".
As presented under section 4.1 and 4.2, the substance is described as a dark green to brown-green resinous material with a melting point between 0.3 and 14.2°C. Therefore no test to determine self-heating properties is required.

Description of key information

Flash Point= 132.5°C (exp) => NOT a flammable liquid (CLP/GHS)

No propagation of a flamme within the 2-min duration of application of the burner flame (exp) => NOT a flammable solid (CLP/GHS).

NOT flammable if contact with air or water (waived).

NO self-heating properties anticipated (waived)

Key value for chemical safety assessment

Flammability:

not classified

Additional information

Considering the high viscosity of the substance (described as a resinous material), Flammability of the substance was evaluated according to UN N1 method, and is presented under point 4.13. Additionally, as a liquid, the substance was also tested for Flash Point according to ISO/EU equilibrium closed cup method, and is presented under point 4.11. Both are considered as key studies.

Justification for classification or non-classification

The measured flash point (132.5°C) is above 60°C, therefore the substance is NOT classified as Flammable liquid according to Regulation (EC) N°1272/2008 (CLP criteria) and UN Globally Harmonized System (GHS criteria).

The result obtained on this kind of substance should be largely influence by small amounts of volatile constituents.

During the UN Test N.1, no propagation of a flamme was observed within the 2-min duration of application of the burner flame. Therefore, the substance is NOT classified as a flammable solidaccording to Regulation (EC) N°1272/2008 (CLP criteria) and UN Globally Harmonized System (GHS criteria).

Based on the chemical structure of the known constituents of the substance and experience in handling, testing and use of the substance, no flammable properties are anticipated if contact with air or water, therefore studies were deemed unnecessary in accordance with section 1 of REACh Annex XI.

Finally considering that the substance is a liquid, no classification as self-heating substance is anticipated.
