BS EN ISO 21663:2020

This standard BS EN ISO 21663:2020 Solid recovered fuels. Methods for the determination of carbon (C), hydrogen (H), nitrogen (N) and sulphur (S) by the instrumental method is classified in these ICS categories:

• 75.160.40 Biofuels
• 75.160.10 Solid fuels

This document specifies the determination of total content of carbon, hydrogen, nitrogen and sulfur in solid recovered fuels by instrumental method. Depending on the amount of test portion, micro or macro instrumental apparatus are used.

This method is applicable for concentrations on dry matter basis of C > 0,1 %, N > 0,1 %, H > 0,1 % and S > 0,05 %.
