Solid mineral fuels. Major and minor elements in coal ash and coke ash. Wavelength dispersive x-ray fluorescence spectrometric method Ingestion-build-47553 This part of EN 60079What is ISO 13605 about? ISO 13605 is a safety standard on major and minor elements in coal ash and coke ash. While coal ash contains contaminants that can potentially contaminate water and air, coke ash burns cleaner. ISO 13605 sets out a wavelength dispersive X ray fluorescence (XRF) procedure for the determination of silicon, aluminium, iron, calcium, magnesium, sodium, potassium, titanium, manganese, phosphorus, and sulphur in coal and coke ash.
