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

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Version / remarks:

2008

Deviations:

no

GLP compliance:

no

Key result

Test procedure:

burning rate test: preliminary screening test

Remarks on result:

substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period

Only a preliminary test was conducted. The test item could not be ignited with a flame, the test item melted. A main test was therefore not necessary.

Interpretation of results:

GHS criteria not met

Conclusions:

The test item is not a highly flammable solid in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.10.

Executive summary:

A study was conducted according to Regulation (EC) No 440/2008, method A.10 to investigate the flammability of the solid test item. The test item melted, but could not be ignited in the preliminary test. Therefore, a main test was not necessary.

Description of key information

The substance has not to be classified as flammable gas, flammable liquid, flammable solid, flammable in contact with water, flammable aerosol, pyrophoric solid, pyrophoric liquid or self-heating substance.

Key value for chemical safety assessment

Flammability:

not classified

Additional information

Flammable gases (reference 4.13-1)

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 liquid (reference 4.11-1)

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.

 

Flammable solids (reference 4.13-2)

A study was conducted according to Regulation (EC) No 440/2008, method A.10 to investigate the flammability of the solid test item. The test item melted, but could not be ignited in the preliminary test. Therefore, a main test was not necessary (reference 4.13-1).

 

Pyrophoric liquids (reference 4.13-3)

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 solids (reference 4.13-4)

In accordance with section 2.10.4 Annex I of Regulation (EC) No 1272/2008 and ECHA guidance on the application of CLP Criteria section 2.10.4.1 the classification procedure for pyrophoric solids need not to be applied when experience in manufacture or handling shows that the solid does not ignite spontaneously on coming into contact with air at normal temperatures (i.e. the solid 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 solid.

 

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

In accordance with column 2 of Regulation (EC) No 1907/2006 Annex VII and ECHA guidance IR/CSA chapter R7.A the UN Test method N.4 for self-heating substances and mixtures do not need to be conducted if preliminary results exclude self-heating of the substance up to 400°C. Thus, no study was conducted and the substance was not considered for classification.

 

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

In accordance with column 2 of REACH Annex VI and with Regulation (EC) No 1272/2008 Annex I section 2.12.4 and ECHA guidance on the application of CLP Criteria section 2.12.4.2 the classification procedure for this hazard class need not to 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 have not to be considered as flammable gas, flammable liquid, flammable solid, flammable in contact with water, flammable aerosol, pyrophoric solid, pyrophoric liquid or self-heating substance.

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, Section 2.12 of Regulation (EC) No 1272/2008, as amended for the fourteenth time in Regulation (EU) 2020/217, and UN GHS Rev 8 (2019) the test item has not to be classified as, readily combustible solid in class 4 Division 4.1, flammable liquid, 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.

In addition, based on handling experience, the test substance is regarded as not being flammable in contact with water (reference 4.13-6) and as not pyrophoric (reference 4.13-4).
