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 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
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

Description of key information

Flammability: highly flammable liquid; experimentally determined flash point < 23 °C at 101.325 kPa.

Key value for chemical safety assessment

Flammability:
highly flammable

Additional information

In accordance with section 1.2 of REACH Regulation (EC) No. 1907/2006 Annex XI the study of flammability does not need to be completed based on weight of available evidence. The substance has an experimentally determined flashpoint < 23 °C and initial boiling point > 35 °C and therefore under CLP Regulation (EC) 1272/2008 is considered a “highly flammable liquid” (Flam Liq. 2).

 

For liquids the primary value for ease of ignition is the flash point conducted using Method A9 ‘Flash Point Method’ of Council Regulation (EC) No 440/2008. The result of the Flash Point test is used to allocate a liquid substance into the appropriate flammability class. Other measures of flammability include pyrophoricity and flammability on contact with water. These can be considered not a concern for the substance and testing waived if consideration of experience in handling and use show that no effects are envisaged. Such a screening procedure represents an intelligent testing strategy for flammability. If applied correctly then only liquid substances for which it is suspected will give a positive result in either the pyrophoric properties or flammability on contact with water tests need to be tested.

 

A review of handling and used implies no pyrophoric properties or flammability on contact with water. Based on experience in handling and use negative results are predicted for pyrophoric properties and flammability of contact with water. Based on the known flash point of the substance it is considered to be flammable.

Justification for classification or non-classification

In accordance with the criteria set in Regulation (EC) No 1272/2008 (CLP Regulation), allylamine is classified as: Flam. Liq. 2; H225: Highly flammable liquid and vapour. The substance has a flash point of < 23 °C and initial boiling point > 35 °C.
