Reference 5

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 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

Additional information

Flammable solids

A preliminary test according to Regulation (EC) No 440/2008 method A.10 was performed to determine the flammability of the test substance. The test item was formed into a powder train. The flame from a gas burner was applied to one end of the powder train for 2 minutes. The burning of the pile was observed. The test was performed twice. In the preliminary test the test item could not be ignited. Based on the results of the preliminary test, no main test was performed. The test item is considered as a not readily combustible solid of Division 4.1. and is not a flammable 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.

 

Flammable 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 flammable liquid.

 

Pyrophoric 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 solids

In accordance with section 2.9.4 Annex I of Regulation (EC) No 1272/2008 and ECHA guidance on the application of CLP Criteria section 2.10.4.2 the classification procedure for pyrophoric solids need not be applied when experience in manufacturing or handling shows that the substance or mixture does not ignite spontaneously when coming into contact with air at normal temperatures. Based on the experience in handling and use the substance is not known to ignite spontaneously when coming into contact with air at normal temperatures. Thus, no study was conducted and the substance was not considered for classification as pyrophoric solid.

Self-heating substances/mixture

In accordance with column 2 of REACH Annex VII and ECHA guidance on IR/CSA chapter R7a, the self-heating study does not need to be performed if preliminary results exclude self-heating of the substance up to 400°C. The test item was determined to be not self-igniting up to 400 °C under the test conditions of EU A.16. Thus, the test UN N.4 for self-heating substances was omitted as self-heating can be excluded.

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 and section 2.12 of Regulation (EC) No 1272/2008, as amended for the twelfth time in Regulation (EU) 2019/521, and UN GHS Rev 7 (2017) 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, substance which in contact with water emits flammable gases in Class 4, Division 4.3, pyrophoric liquid, pyrophoric solid in class 4, Division 4.2, flammable gas in class 2 or as aerosol in class 2.
