Steps
Understand EN 13561 wind classes run 0-3, with Class 1 ≈ Beaufort 4 (20-28 km/h), Class 2 ≈ Beaufort 5 (29-38 km/h), and Class 3 ≈ Beaufort 6 (39-48 km/h); this is a European mechanical-performance rating, not a US structural code
Treat the EN class as a manufacturer performance spec (max safe operating wind before manual/auto retraction), not as a substitute for US structural wind design
For any US permit requiring engineered wind loads, have a licensed engineer perform a separate ASCE 7 wind-load calculation for the specific US location/exposure; EN 13561 classification alone will not satisfy US plan review
Ask the manufacturer/importer for the EN 13561 test certificate and translate the class into a practical auto-retract wind-sensor setting at installation
Known gotchas
EN 13561 classes describe European Beaufort-scale wind ranges, not US mph structural design wind speeds; don't let a sales rep imply a Class rating alone satisfies a US building department's engineered wind-load requirement
Even Class 3 (the highest EN 13561 rating) corresponds to roughly 39-48 km/h (about 24-30 mph) sustained wind, well below US hurricane-zone design wind speeds
