Justification for classification or non-classification

Although DuPont internal data shows that within a very narrow concentration range in air (4.0 - 4.9% by volume) PFBE is very marginally flammable according to ASTM E-681-98, it is classified as a flammable liquid on account of its flash point of -17°C and inital boiling point of 58° C according to EU Directive 67/548/EEC and EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
