Flammability:
non flammable

Additional information

In a key study, the flammability of the test item Phosphonic acid (Phosphorous acid Flake) was determined based on the procedures indicated by the following internationally accepted method:

- EU Method A.10

The test item Phosphonic acid (Phosphorous acid Flake) could be ignited, but the test item did not propagate combustion along 200 mm of the powder train within 4 minutes. Therefore, the test item is considered not to be highly flammable.

Justification for classification or non-classification

As Phosphonic acid (Phosphorous acid flake) could be ignited, but did not propagate combustion along 200 mm of the powder train within 4 minutes, it is not classified as flammable according to the classficiation criteria outlined in 67/548/EEC (DSD) and 1272/2008 (CLP).
