Description of key information

1) The flammability of a substance is determined following the methods N.1 (UN-manual of testing) or A.10 (EU-method). 
However, in accordance with section 2 of REACH Annex XI, a study is technically not feasible as the substance is a liquid. The flammability of a liquid is described by the flash point.
2) Pyrophoric properties are determined following the methods N.3 (UN-Manual of testing) or A.13 (EU-method).
However, in accordance with section 1 of REACH Annex XI, a study does not need to be conducted as it is scientifically unjustified. Based on experience during handling and use, no pyrophoric properties were observed and the structure does not give a reference to pyrophoric properties.
3) In accordance with section 1 of REACH Annex XI, the study on flammability in contact with water does not need to be conducted as the substance contains no metals or metalloids and therefore will not release flammable gases in contact with water.
4) In accordance with Annex I, part 2, section 2.11 of the CLP regulation No 1272/2008 a study on self-heating behaviour of the substance does not need to be conducted, as the substance has a low melting point (< 160°C) and is completely molten at this temperature.
5) In accordance with Annex I, part 2, section 2.8.4.2 of the CLP regulation No 1272/2008 a study on self-reacting behaviour of the substance does not need to be conducted, as the structural formula of the substance contains none of the functional groups quoted in Recommendations on the Transport of Dangerous Goods - Manual of Tests and Criteria (fifth revised edition, 2009, appendix 6, table A 6.2) which may indicate self-reactive properties. Therefore, it can be concluded by expert judgement that o-toluidine is not self-reactive.

non flammable

Additional information

Justification for classification or non-classification

o-Toluidine is not flammable, it has no pyrophoric properties, no flammability in contact with water, is not a self-heating and a self-reacting substance, is not an organic peroxide; and hence no classification according to both Directive 67/548/EEC and GHS (Regulation EC 1272/2008) is required.
