Reference 1

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

Reference 2

Endpoint:

flammable solids

Data waiving:

Justification for data waiving:

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

Reference 3

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

Justification for type of information:

The test method for the determination of the pyrophoric properties of a substance as described for liquid materials in EU Method A.13, was replaced by a theoretical based evaluation.

The chemical structure of Sika Hardener LG indicates that there are no groups associated with pyrophoric properties. The test substance does not contain any chemical group that might lead to spontaneous ignition shortly after coming into contact with air at room temperature (Ref.: R.7a: Guidance on information requirements and chemical safety assessment, EU-Document (May 2008)). Based on experience in handling and use there is also no indicator for pyrophoric properties and therefore no study needs to be carried out.

Endpoint:

pyrophoric solids

Data waiving:

study technically not feasible

Justification for data waiving:

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

Reference 5

Endpoint:

self-heating substances / mixtures

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 completely molten at 160°C

Reference 6

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

Description of key information

The substance is not considered as flammable, flammable in contact with water, pyrophoric, and self-heating substance.

Key value for chemical safety assessment

Flammability:

not classified

Additional information

Flammable gases

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 liquid

As Sika Hardener LG is a liquid at 20 °C and normal pressure, a flash point of 195.5 ± 0.7 °C at 1013.25 hPa was determined for Sika Hardener LG, using a non-equilibrium method (Pensky-Martens apparartus) .

 

Flammable solids

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.

 

Pyrophoric liquids

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.

 

Pyrophoric solids

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.

 

Self-heating substances and mixtures

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 ECHA guidance on the Application of the CLP Criteria section 2.11.4.2.

 

Substances which, in contact with water, emit flammable gases

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 doesn't 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

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, as amended for the fifteenth time in Regulation (EU) No 2020/1182, and UN GHS Rev 8 (2019) the substance has not to be classified as 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.
