Fe3P was found not to be oxidising.
A determination of oxidising properties was performed as part of a package of Physicochemical testing (Huntingdon Life Sciences, 2011, Study FGE0016). The oxidising properties determination was performed according to EC Method A17, and the study was conducted in compliance with GLP.
Dried test substance was mixed with powdered cellulose in a ratio of 2:1, and formed into a cone on a non-porous, non-flammable surface, and ignited with a gas burner, and the rate of burning recorded. The test was repeated with test material: cellulose in ratios of 1:1 and 1:2, and with a reference mixture of barium nitrate to cellulose 3:2. All three test material mixtures were found to burn very slowly to completion; each mixture burned more slowly than the reference mixture.
As all test substance/cellulose mixtures burned significantly more slowly than the reference mixture, Fe3P is considered to be non-oxidising.
When mixed with a combustible material (cellulose), Fe3P was found to burn less rapidly than a reference mixture of an oxidising material and cellulose, and therefore was concluded not to display oxidising properties. On this basis, Fe3P does not meet the criteria for classification as an Oxidising Solid under the CLP Regulation (Regulation (EC) 1272/2008). Similarly, Fe3P is not classified as an oxidiser according to the Dangerous Substances Directive (Directive 67/548/EEC).
