Flammability: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 thiophosphoryl trichloride is a liquid. The flammability of a liquid is described by the flash point.Pyrophoric properties: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.Flammability on contact with water:In accordance with section 1 of REACH Annex XI, the study on flammability in contact with water does not need to be conducted as thiophosphoryl trichloride contains no metals or metalloids and therefore will not release flammable gases in contact with water.
