Leather. Organic fluorine - Determination of non-volatile compounds by extraction method using liquid chromatography/tandem mass spectrometry detector (LC-MS/MS) Ingestion-build-93833 and mass of fine-grain structuralWhat is this standard about? This document specifies a test method for detection and quantification of extractable neutral, ionic, long, medium and short chain perfluorinated and poly fluorinated substances in leather and coated leather. This document, taking into account the three dimensional distribution of the fibres within leather, makes the evaluation of the perfluorinated and poly fluorinated substances with respect to the mass.
