Reference

Reference 1

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

Reference 2

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

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

Description of key information

The substance is non-flammable. Furthermore, the substance is neither pyrophoric nor flammable upon contact with water.

Key value for chemical safety assessment

Flammability:

non flammable

Justification for classification or non-classification

The liquid test item is non flammable based on flash point (>93°C) and boiling point (high, could not be determined under vacuum).

Ignition on contact with air:

The test item is according to the Guidance on the Application of the CLP Criteria (1) known from practical handling to be not pyrophoric. It is produced, handled and stored under normal conditions in air without any observation in respect to pyrophoric properties. Therefore, there is no likelihood that the test item possesses pyrophoric properties.

 Release of flammable gases in contact with water:

The test item does according to the UN Manual of Tests and Criteria (2) show one or more of the following properties:

1. The chemical structure of the substance does not contain metals or metalloids;

2. Experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured in water or washed with water;

3. The substance is known to be soluble in water to form a stable mixture.

Therefore it is considered as not forming flammable gases in contact with water.

According to this fact further testing in respect to these properties is not required.
