Description of key information

Because of the result of the preliminary test the test substance is not considered a flammable solid of division 4.1.

The substance has no pyrophoric properties and does not liberate flammable gases in contact with water.

The substance is just used as an aqueous solution and is therefore not classified as a self-heating substance or mixture.


Key value for chemical safety assessment

Flammability:
not classified

Additional information

Because of the result of the preliminary test, according “UN-Recommendations on the Transport of Dangerous Goods (6th revised edition), Manual of Tests and Criteria”, Part III, Test N.1, Class 4.1, Chapter 33.2.1.4, the test substance is not considered a flammable solid of division 4.1.

The substance or mixture does not need to be classified as pyrophoric as based on chemical structure pyrophoric properties are not to be expected.

The substance or mixture does not need to be classified as a substance which in contact with water emit flammable gases as based on chemical structure flammability in contact with water is not to be expected.

The substance is just used as an aqueous solution and is therefore not classified as a self-heating substance or mixture.

The dried substance has an onset temperature of 219 °C at the Grewer oven test and therefore further test are required but as the substance is just used as an aqueous solution there will be no further tests.

Justification for classification or non-classification

In accordance with Annex I, Section 2.1, Section 2.2, Section 2.3, Section 2.7, Section 2.9, Section 2.10 Section 2.11, Section 2.12 of Regulation (EC) No 1272/2008 and UN GHS Rev 6 (2015) the substance has not to be classified as readily combustible solid in class 4 Division 4.1, 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.
