Those are two norms developed for the certification of paragliders, AFNOR in France, adopted by SHV and most countries, DHV in Germany. Without going into detail at this point, their categories essentially classify which paragliders are suitable for which pilot levels. Those categories are Standard, Performance, Competition in AFNOR/SHV and Class I, II and III in DHV. Paragliders are not certified by the FAA. But the voluntary certification as described above is certainly a good indication for what is generally suitable for a beginner, intermediate or very advanced pilot.
