MAN MADE VITREOUS FIBRES
LABORATORY
Classification of artificial vitreous fibres (AVF) by measuring the length-weighted mean geometric diameter of the fibres minus two standard errors (DLG-2ES) and the percentage of alkaline oxides and alkaline earth oxides (EC Regulation 761/2009 European ECB Method) with Scanning Electron Microscopy and Chemical Microanalysis (SEM-EDS).
Artificial vitreous fibres (AVF) are a group of inorganic fibres used as insulators in several industrial products (ovens, pipes, foundry moulds, insulation panels, roofing, etc.). Among the AVF, we can consider the following types of fibres: insulation wool, glass wool, fibres for special purposes, rock wool, slag wool, refractory ceramic fibres, alkaline earth silicate wool, HT wool.
Measuring by SEM-EDS technique of the length-weighted mean geometric diameter minus two standard errors (DLG-2ES) and the percentage of alkaline oxides and alkaline earth oxides..
