> 70208,IS,,ISO 622:2016,Solid mineral fuels — Determination of phosphorus content — Reduced molybdophosphate photometric method,Combustibles minéraux solides — Dosage du phosphore — Méthode photométrique au molybdophosphate réduit,2016-11-18,2,['75.160.10'],ISO/TC 27/SC 5,9599,[4742],[86989],['en'],6,"<p>ISO 622:2016 specifies a reduced molybdophosphate photometric method for the determination of the total phosphorus content of hard coal, lignites and coke. Two methods for taking the phosphorus into solution are specified, namely extraction from the coal or coke ash with acid or by repeated oxidation of the coal or coke, by acid, to remove carbonaceous matter.</p>"
