Justification for data waiving:
other:
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:
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

Description of key information

According to REGULATION (EC) No. 1272/2008 (CLP) not classified with regard to flammable liquids.

According to UN GHS v. Rev. 6 (2015) classified as Flammable Liquids Category 4 (Combustible liquid).

Key value for chemical safety assessment

Flammability:
not classified

Additional information

See below for details on classification requirements!

Justification for classification or non-classification

The liquid test item is non flammable based on flash point and boiling point according to REGULATION (EC) No. 1272/2008 (CLP).

The liquid test item would be classified as flammable liquid category 4 (Combustible liquid) based on flash point and boiling point according to UN GHS Rev. 6 (2015).

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

 

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.

 

According to (1), the phenomenon of self-heating applies only to solids. The surface of liquids is not large enough for reaction with air and the available test method is not applicable to liquids. Therefore liquids are not classified as self-heating.
