Link to relevant study record(s)
- Endpoint:
- flammable solids
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted because the substance is a liquid
- 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
- 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
- the study does not need to be conducted because the substance is known to be soluble in water to form a stable mixture
- 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 a liquid
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
According to ECHA Guidance on the Application of the CLP Criteria (v5.0, July 2017, §2.11.4.2.), the phenomenon of self-heating generally applies only to solids. The surface of liquids is not large enough for reaction with air and the test method (UN N4) is not applicable to liquids. Therefore liquids, unless adsorbed, are not classified as self-heating.
Moreover, the substance is a volatile liquid (and volatilisation is an endothermic phenomenon), and also the chemical structure does not contain metals, which are typically self-heating substances.
Therefore the hazard class does not apply. - Endpoint:

- Interpretation of results:
- Category 1 (flammable gases) based on GHS criteria
- Conclusions:
- The flammability range of the substance in air at 20°C and standard pressure of 101.3kPa is 8.6%Vol to > 70%Vol.
- Executive summary:
The determination of the explosion limits of the test item in air was conducted according to the test method DIN EN 1839:2017. The work was accredited under ISO 17025.
The test was conducted in a 5 L sphere at the temperature of approx. 20°C.
A permanent spark with an ignition energy of approx. 10 Joule was used as ignition source.
According to the results the lower explosion limit (LEL) of the test item is 8.6 %Vol and the upper explosion limit (UEL) is higher than 70 %Vol. The test was terminated at the concentration of 70 %Vol.
Based on the results of the test the item in its gaseous form is to be considered a flammable gas.
Referenceopen allclose all
The test was terminated at the concentration of 70 %Vol because The sample quantity was not sufficient to test concentrations higher than 70%Vol.
As the information gathered on the substance during the test was considered sufficient for the hazard assessment and risk management of the test item, the test was terminated at the concentration of 70%Vol.
Description of key information
As the boiling point of the test item is approx.20 °C, the flammability was determined on two forms: liquid and gas.
The flammability of the liquid subtance was evaluated using the flash point and the boiling point: the substance has a flash point < -20°C and a boiling range of 18.8°C - 23°C.
The flammability of the gaseous substance was determined by the EN 1839 method: the flammability range in air was determined to be 8.6%Vol - >70%Vol.
Based on the chemical structure and experience, no flammable properties are anticipated if contact with air or water, or no self-heating, therefore studies were deemed unnecessary.
Key value for chemical safety assessment
- Flammability:
- flammable
Additional information
Justification for classification or non-classification
Flash point is lower than 23°C and boiling point is lower than 35°C, therefore the test item is classified as Flammable Liquid Category 1 based on GHS/CLP criteria.
Under the determination of the flammable range in air of the substance in its gaseous form, ignition was observed at concentrations below 13%Vol and above 6%Vol. According to GHS/CLP criteria the test item is classified as Flammable Gas Category 1B.
