Reference 1

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

Endpoint:

flammable gases

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted because the substance is a liquid

Justification for data waiving:

the study does not need to be conducted because the substance is a liquid

Reference 4

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

Key value for chemical safety assessment

Flammability:

flammable

Additional information

Flammable gases (4.13-1)

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

 

Flammable solids (reference 4.13-2)

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

 

Flammable liquids (reference 4.11-1)

A study similat Regulation (EC) No 440/2008 Method A.9 was perfomed to determine the flash point of the test item using the Setaflash apparatus and the closed cup method. 2 mL of the test item were injected in the closed cup and the flame was brought to the vapours in the closed cup. The flash point of the test item is below room temperature (20 °C) as the ignition starts immediately when the flame was brought into contact with the vapour in the closed cup.

Pyrophoric properties of solids (reference 4.13-3)

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

 

Pyrophoric properties of liquids (reference 4.13-4)

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 2.9.4.2 the classification procedure for pyrophoric liquids need not to be applied when experience in manufacture or handling shows that the liquid does not ignite spontaneously on coming into contact with air at normal temperatures (i.e. the liquid is known to be stable at room temperature for prolonged periods of time (days)). 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 liquid.

Self-heating substances and mixtures (reference 4.13-5)

In accordance with ECHA guidance on the Application of the CLP Criteria section 2.11.4.2 and ECHA guidance on IR/CSA chapter R.7a section R7.1.10.7 the test does not to be conducted as in general liquids are not classified as self-heating since the phenomena applies only to solids and the test method is not applicable to liquids according to guidance on the Application of the CLP Criteria section 2.11.4.2.

 

Substances which, in contact with water, emit flammable gases (4.13-6) 

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

Section 2.4.2 of Guidance on the application on the CLP Criteria state as follows: “Aerosols, this means aerosol dispensers, are any non-refillable receptacles made of metal, glass or plastics and containing a gas compressed, liquefied or dissolved under pressure, with or without a liquid, paste or powder, and fitted with a release device allowing the contents to be ejected as solid or liquid particles in suspension in a gas, as a foam, paste or powder or in a liquid state or in a gaseous state." Thus, as the substance does not meet the definition for aerosol, the test for aerosols was waived. Consequently the substance has not to be considered for classification for this hazard class.

In conclusion, the substance does not have to be considered as flammable gas, flammable solid, flammable in contact with water, flammable aerosol, pyrophoric solid, pyrophoric liquid or self-heating substance. The test item is classified as flammable liquid in Cat. 2.

Justification for classification or non-classification

Classification, Labelling, and Packaging Regulation (EC) No 1272/2008

In accordance with Annex I section 2.2, section 2.3, 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 tenth time in Regulation (EU) No 2017/776, and UN GHS Rev 7 (2017) the test item has not to be classified as 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. The substance has to be classified as flammable liquid Cat. 2 (H225: Highly flammable liquid and vapour) according to Regulation (EC) No 1272/2008, Annex I section 2.6.
