Key value for chemical safety assessment

Flammability:
not classified

Additional information

Flammable solids

A study was performed in accordance with the test method described in the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Part III, Test N.1. In a pretest localized burning or glowing with practically no spreading was observed. Therefore, the preliminary screening test was negative and the test substance is not considered as a flammable solid. The result does not lead to a classification.

Flammable liquids

In accordance with column 2 Annex VII section 7.9 of Regulation (EC) No 1907/2006 (REACH), the test on flash point does not need to be coducted as the test substance is solid.

Flammable gases

The test item is a solid at ambient conditions. This hazard class is only applicable for gases. Thus, the substance was not considered for classification as flammable gas.

Pyrophoric properties of liquids

The test item is a solid at ambient conditions. This hazard class is only applicable for liquids. Thus, the substance was not considered for classification as pyrophoric liquid.

Pyrophoric properties of solids

In accordance with section 2.10.4.1, Annex I of Regulation (EC) No 1272/2008, the classification procedure for pyrophoric solids need not to be applied when experience in manufacture or handling shows that the substance or mixture does not ignite spontaneously on coming into contact with air at normal temperatures (i.e. the substance is known to be stable at room temperature for prolonged periods of time (days)). Thus, no study was conducted and the substance was not considered for classification as pyrophoric solid.

Self-heating substances and mixtures

A study was conducted in accordance with the test method described in the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Test N.4

to determine the self-heating properties of the test item. A negative result was obtained in the test and therefore, the substance is not classified as a self-heating substance of Division 4.2.

Substances which, in contact with water, emit flammable gases

In accordance with column 2 of REACH Annex VII and with Regulation (EC) No 1272/2008 Annex I, section 2.12.4.1(b) the classification procedure for this hazard class need not be applied. Based on the experience in handling and use the substance does not react with water and in addition the test substance is not pyrophoric. Thus, no study was conducted and the substance was not considered for classification.

Flammable Aerosols

In accordance with Annex I of Regulation (EC) No. 1272/2008, section 2.3 the classification procedure for this hazard class does not apply, since the test substance is not used as an aerosol. Thus, no study was conducted and the substance was not considered for classification.

Justification for classification or non-classification

In accordance with Annex I Section 2.2, Section 2.3, Section 2.6, Section 2.7, Section 2.9, Section 2.10 Section 2.11, Section 2.12 of Regulation (EC) No 1272/2008, as amended for the tenth time in Regulation (EC) No 2017/776, and UN GHS Rev 6 (2015) the test item has not to be classified as, flammable liquid, readily combustible solid in class 4 Division 4.1, self-heating substance in Class 4 Division 4.2, 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.
